The Athletics need innings their young lineup can grow behind

The decision: buy rotation stability, keep the hitters' jobs open

The Athletics allowed 937 runs in 2026. That is the first number an offseason plan must address. The young offense has genuine promise, led by Nick Kurtz and supported by Shea Langeliers, Tyler Soderstrom and Henry Bolte. But the club finished 64-98 because a lineup scoring 699 runs could not keep pace with its pitching and defensive losses. A winter centered on another expensive corner bat would leave the largest problem intact.

Our preferred plan buys Tyler Mahle for 28 starts and 150 innings, Michael Soroka for 24 starts and 125 innings, and Jonah Heim for a limited backup-catching role. The proposed terms are two years and $28-32 million for Mahle, one year and $8-10 million for Soroka, and one year and $2-3 million for Heim. Including a separate $6-8 million depth reserve, annual additions total $30-37 million. The resulting player-allocation envelope is $116.84-127.84 million. These are S&S negotiating ceilings, subject to current medical, market and compensation review.

The first alternative replaces Mahle with Nick Martinez at two years and $26-30 million. Martinez takes 160 innings, ten more than Mahle, while Jacob Lopez's allocation falls by ten. The internal plan purchases none of the three players and assigns all their work to named organizational alternatives. It is cheaper, but it asks much more of pitchers whose command, health or major-league performance is unsettled. No anonymous reserve is credited with innings.

The investment case is developmental as well as competitive. The Athletics need to learn which hitters belong in a durable lineup while limiting the number of games in which the staff loses control of the score early. Mahle and Soroka do not make the club a contender by themselves. They create a more credible environment for evaluating the existing talent, at prices that leave room for subsequent decisions.

The setback was larger than twelve fewer wins

The Athletics fell from 76 wins to 64. Their run margin deteriorated from minus-84 to minus-238, a 154-run change. Offense accounted for 34 fewer runs; prevention accounted for 120 additional runs allowed. The pitching problem became substantially larger while the offense also lost ground. The 2024-26 comparison does not support a straight-line improvement narrative.

The completed game log shows a 23-23 record in one-run games and 7-6 in extra innings. Those narrow-game results were not the principal cause of a 98-loss season. Improving late-inning execution matters, but a bullpen-only diagnosis would miss the scale of the broader deficit. The starters had a 5.61 ERA in 768 1/3 innings, and the relievers had a 5.43 ERA in 661 2/3. Both groups need improvement.

The season also illustrates why a fixed win forecast would be misleading. Restoring health, changing the defense and buying innings can improve the roster without guaranteeing the precise number of runs saved. The useful offseason question is which changes have identifiable jobs, reasonable prices and credible fallback plans. This report tests those decisions against the actual roster rather than treating the previous win total as destiny.

Home conditions matter, but do not explain everything

The Athletics scored 397 runs at home and 302 on the road. Their OPS was .781 at home and .655 away. Pitching split even more sharply: 562 runs allowed and a 6.34 ERA at home, versus 375 and 4.62 on the road. The club went 32-49 in both settings. These are observed splits, not a calculated park adjustment. They combine environment, opponents, personnel and performance.

The road offense is an important warning against treating every attractive home batting line as transferable production. The road pitching, meanwhile, still was not strong enough to make environmental explanations a complete defense of the staff. A 4.62 road ERA leaves substantial room for better pitching even before discussing the home conditions.

The practical response is to emphasize command, playable defense and honest workload limits. It is not to assume that a particular pitcher is immune to the home environment, or that every disappointing result will normalize. The preferred starters have evidence beyond one favorable split. The position plan also reduces unnecessary exposure to some of the weakest defensive combinations while preserving the young hitters' opportunities.

Start with the roster that actually exists

The November 3 major-roster response contains 40 names. Luis Severino remains after exercising his $22 million player option. Jeffrey Springs and Jeff McNeil are free agents after their club options were declined. Heim and Mark Leiter Jr. also entered free agency. None of their 2026 contributions can be silently carried into a retained 2027 roster.

Nate Eaton is an Athletic after the October 29 trade with Boston for Jareth Rayo. Brian Serven was outrighted to Las Vegas and appears in the organizational records rather than on the current major roster. A proposed Heim return requires a new agreement. A Serven appearance requires selection and a legal roster place. Those are different transactions even though both players caught for the club in 2026.

The same distinction applies to the farm. Jamie Arnold and Brayan Buelvas are organizational players whose proposed major-league work requires selection. Brett Harris's Las Vegas performance remains historical evidence, but his later moves culminated in a November 2 Philadelphia waiver claim. He is not a retained Athletics depth solution. Player IDs, current status and transaction history control the classification when familiar names appear in older team tables.

The lineup has a core, not nine settled answers

Kurtz produced an .879 OPS in 434 plate appearances. Langeliers reached .802 with 23 homers, Soderstrom .810 with 19, and Gelof .797 with 22. Bolte added a .764 OPS in 473 plate appearances. Those are meaningful offensive pieces. They coexist with Wilson's .686, Rooker's .670 and a series of limited or unsuccessful depth samples.

The main plan does not buy a new middle-order hitter. It gives Kurtz 550 plate appearances, Soderstrom and Rooker 450 each, Langeliers 480, and Butler and Bolte 500 each. Those allocations are conditional on current health and performance. They are not predictions that every established hitter rebounds or that every young player sustains his best stretch.

Third base remains a competition among Max Muncy, Tommy White, Darell Hernaiz and Joshua Kuroda-Grauer. That is less comfortable than writing an established veteran into the lineup. It preserves information the club needs, however, and directs the first spending toward a much larger pitching deficit. A later third-base purchase would require a new job and a new playing-time budget, not a fifth name added to the same assignment.

Separate the established batting record from a promising year

Kurtz followed a 1.002 OPS in 2025 with .879 in 2026. His 79 walks support the value of his approach even as the headline production declined. Langeliers' last three seasons were .738, .861 and .802. Soderstrom followed .820 with .810 in two substantial seasons. Their recent records provide a stronger foundation than simply selecting each player's best year.

Gelof's rebound from a limited .502 OPS season in 2025 to .797 is encouraging, but it still requires context. Butler's .807 in 2024 was followed by .710 and .720. Rooker moved from .927 to .814 to .670, with only 203 plate appearances in the most recent season. Health and workload help explain why those records need care; they do not justify automatically replacing the latest evidence with an earlier peak.

Statcast also separates several encouraging results from their underlying contact. Kurtz had a .381 wOBA and .374 expected wOBA, a close pairing. Langeliers was .347/.352. Bolte's .341/.317, Soderstrom's .349/.327 and Gelof's .346/.323 were less aligned. Kuroda-Grauer's .392/.311 came in a very small major-league sample. Expected statistics describe the quality of observed events; they are not next-season projections.

Use platoon evidence without turning small samples into permanent roles

Kurtz had a .728 OPS against left-handers and .972 against right-handers. Soderstrom was .712/.857. Those splits support selective rest and matchup choices, but both remain important everyday-development players. Benching them mechanically whenever a left-hander starts would sacrifice opportunities to improve and would overstate the precision of one season's split.

Langeliers' 1.000 OPS against left-handers contrasted with .722 against right-handers. Heim's full-season .855 against left-handers and .471 against right-handers makes him an awkward offensive complement if used only as a generic platoon partner. His proposed role is workload protection and competent backup catching, not a claim that his bat solves Langeliers' less productive side.

Bolte's .817 against left-handers and .739 against right-handers gives the outfield some useful flexibility. Rooker's .513 against left-handers came in just 49 plate appearances and should not define his future role by itself. The best application of the splits is to choose occasional matchups among healthy, available players while continuing to evaluate the broader record.

Defense needs a position plan, not a single team label

Butler's range record moved from minus-1 Outs Above Average in 2024 to plus-4 in 2025 and minus-11 in 2026. Wilson moved from minus-3 in each of his first two seasons to plus-9. Neither one-year extreme should be treated as an immutable talent level. The opportunity counts, positions and health context matter.

Bolte's plus-3 in 363 opportunities supports a substantial center-field assignment. Clarke's plus-3 came in 77 opportunities, following plus-13 in 2025. His defensive value deserves an opportunity, but an .409 OPS in 87 plate appearances means that simply increasing his playing time is not a costless solution. The preferred plan gives Bolte 100 center-field starts, Clarke 42 and Eaton 20.

Soderstrom and Muncy each finished at minus-7 OAA, White at minus-5, and Cortes and Walton at minus-9. Those figures argue for careful deployment. They do not establish that all the lost outs would disappear with one replacement. The plan gives Soderstrom some first-base and designated-hitter work, limits Cortes' outfield starts and keeps multiple third-base alternatives available. Range is only part of total defense; catching, throwing and receiving require separate evidence.

Catching is a workload purchase

Langeliers is the only catcher in the current 40-name snapshot. That makes the second catching job a real roster need even if the club spends most of its money on pitching. He receives 110 catching starts in this model, plus five at designated hitter. Heim receives 42, and Serven ten after selection. The seasonal allocation provides rest without treating Langeliers as a 162-game catcher.

Langeliers' full-season framing value was approximately minus-4.82 runs, with total catching value near minus-4.23. Heim was about minus-1.63 in framing and minus-1.43 in total catching value. Those measures overlap and must not be added. Heim's recent receiving record does not justify calling him an elite defensive acquisition. The argument for a one-year $2-3 million offer is narrower: an experienced second catcher at a limited cost, with 180 plate appearances rather than a starting job.

If Heim is unavailable or fails the current review, Serven adds 120 plate appearances and 30 catching starts; Bryan Lavastida adds 60 plate appearances and 12 catching starts after selection. Serven's .939 Triple-A OPS does not erase his .599 major-league OPS. Lavastida's .688 at Triple-A provides another caution. The internal route is executable on paper but carries more uncertainty, which is why a modest external purchase remains preferred.

Health changes the allocation before it changes the headline

Wilson underwent left-shoulder labral surgery in September and also received a right-knee PRP injection. Soderstrom had surgery for left-hip impingement in August. Rooker's late-September club update described a left-knee bone bruise and a hitting and running progression. Kurtz was recovering from a right-thumb strain. These dated reports establish why a fresh readiness check is required; November roster activations do not prove that rehabilitation is complete.

The pitching conditions are equally consequential. Ginn's right-elbow impingement, Severino's right-shoulder strain and Jump's left-shoulder impingement all require current review. Sterner had right-knee surgery. Hoglund's left-hip surgery leaves him outside the principal innings budget. The plan does not rely on all injured pitchers becoming available simultaneously.

De Vries underwent surgery for right-shoulder instability on September 14, with the club hoping for a return during the first two months of 2027. He receives zero principal major-league plate appearances. Arnold's facial fractures did not require surgery according to the dated update, but his eight proposed major-league starts still depend on recovery, development and selection. The report budgets opportunity conservatively instead of turning a prospect ranking into a medical timetable.

Muncy's knee condition also requires an offseason decision. The 300-plate-appearance allocation is conditional. White, Hernaiz and Kuroda-Grauer receive the replacement work if he cannot fill it. Multiple simultaneous failures would require a combined revision; the single-player branches later in the report should not be added mechanically when they use the same replacements.

The internal rotation needs help even before the medical questions

Ginn's 3.71 ERA in 138 1/3 innings was the best substantial starter result, but his 4.12 xERA and 57 walks discourage treating him as a finished top-of-rotation answer. Lopez's 5.47 ERA contrasted with a 3.65 xERA, suggesting better contact-quality evidence than his results alone convey. That does not guarantee a rebound. It supports giving him another defined opportunity rather than discarding him solely on ERA.

Perkins struck out 140 in 121 innings but also walked 51 and finished with a 6.10 ERA. Jump had 108 strikeouts and 46 walks in 98 2/3 innings. They are part of the future evaluation, but the preferred plan does not ask both to supply a full veteran workload. Perkins splits 95 total innings between starting and relief. Jump has 95 starting innings, contingent on his shoulder review.

Springs' 142 2/3 innings disappear from the retained roster when his option is declined. His 6.18 ERA is historical evidence, not a reason to pretend the innings no longer need replacing. Severino's $22 million salary also does not create 180 healthy innings. His principal allocation is 20 starts and 105 innings, with a fully specified failure branch.

Relief volume is part of the rotation problem

The bullpen covered 661 2/3 innings in 2026. The preferred plan reduces that burden to 585 by purchasing starter work. The reduction is valuable only if the starters actually supply the innings. It does not itself guarantee better prevention, and it cannot be credited twice as both a rotation gain and a separate bullpen acquisition.

Medina had 93 strikeouts and 39 walks in 73 innings; Harris had 88 and 42 in 70 1/3. Their strikeout ability is useful, and their walk totals are a material constraint. Each receives 80 innings, a substantial bulk role rather than an automatic late-inning designation. Alvarado and Blewett receive 60 and 55. Sterner's 45 depend on current recovery evidence.

The remaining relief work goes to named pitchers with explicit limits. Barnett, Johnson, Roycroft, Morris, Basso, Tur and Rom do not become proven merely because the table needs 585 innings. Their recent results explain why the roster needs both a depth reserve and early performance checkpoints. Steven Okert is an attractive relief alternative, but purchasing him before resolving the rotation would leave the larger workload gap intact.

The farm offers alternatives, with real transition costs

Arnold's Double-A line was 113 1/3 innings, a 3.57 ERA, 125 strikeouts and 49 walks. His Triple-A sample was only five innings. That supports an initial major-league opportunity of eight starts and 40 innings after selection, not an immediate 150-inning guarantee. The no-acquisition branch raises his workload substantially and must be judged more cautiously.

De Vries' .836 Double-A OPS and Devin Taylor's .943 there are meaningful developmental evidence. Neither is assigned a principal major-league batting role. De Vries has a documented surgical recovery, and Taylor still needs to demonstrate readiness beyond that level. A roster can value prospects highly without spending their future production in an offseason forecast.

Kuroda-Grauer's .855 Triple-A OPS and strong contact sample support more responsibility, but his 74 major-league plate appearances remain too few to establish an .899-OPS true talent. White's .834 Triple-A OPS contrasted with .600 in the majors. Buelvas' .840 Triple-A OPS earns a limited depth consideration after selection. Brett Harris's strong Las Vegas line is retained only as historical evidence because he has departed the organization.

The pitching fallback becomes less comfortable farther down the list. Morales walked 51 in 71 1/3 Triple-A innings. Nett walked 39 in 22. Neither receives principal innings. Nett appears only in an explicitly severe combined-failure branch, where the poor command evidence makes the weakness visible. A named contingency is more honest than an unnamed replacement, but it is not an endorsement of immediate readiness.

Price the candidate's full season, then assign the job

Mahle's full season was 149 innings, a 3.99 ERA, 137 strikeouts and 46 walks, with a 3.95 xERA. The proposal buys 150 innings at an annual ceiling of $14-16 million for two years. His strong Atlanta finish should not replace the full-season record as the pricing basis. He is a middle-rotation purchase with a defined job, not an ace inferred from a short stretch.

Soroka supplied 116 innings with a 3.41 ERA, 114 strikeouts and 29 walks. His 4.12 xERA is a useful counterweight to the ERA. The proposed 125 innings and one-year $8-10 million limit reflect both his value and his August right-arm inflammation. September activation establishes a return to the roster, not a current medical clearance. If the arm review fails, the proposal fails with it.

Martinez offers a different profile: 180 innings, a 3.10 ERA, 109 strikeouts and only 26 walks, with a 3.98 xERA. His two-year $26-30 million alternative buys 160 innings here. The extra ten innings reduce Lopez's workload; they are not added above the season total. Mahle remains narrowly preferred for his stronger strikeout profile at a modestly higher price, but current medical information and actual terms could reverse that order.

Taillon's 27 homers in 86 innings and Littell's 30 in 124 1/3 make them poor principal answers to this particular prevention problem. Bassitt's 102 innings should not be casually converted into a 180-inning floor. Kelly and Dominguez are current players under other clubs' control, not assumed free agents. Different names were tested; novelty alone did not produce a better recommendation.

Repeated targets require repeated justification

Mahle also appears in the Angels and Braves preparation at two years and $28-32 million. The Athletics use the same ceiling for 150 innings, matching the Angels' workload and sitting just below Atlanta's 155. Here he displaces additional work from Lopez, Jump, Perkins and Morris. Atlanta's case protects a different rotation, while the Angels' case reduces a different developmental burden. The shared name does not make the jobs identical.

Soroka's one-year $8-10 million range and 125-inning role match the Washington and Colorado comparisons. The Athletics do not invent a discounted price because several clubs could use him. Martinez retains the two-year $26-30 million ceiling considered in the Brewers, Royals, Braves, Washington and Boston work. Each dossier is an independent negotiation scenario; one pitcher cannot fill all those jobs simultaneously.

Heim is a small proposed retention, with 180 plate appearances and 42 catching starts. That is a different acquisition from the larger Carson Kelly role considered for the Angels. The Athletics already have Langeliers and should not pay for a starting catcher merely because one was recommended elsewhere. No outgoing prospect package is included in the preferred free-agent plan. Compensation and roster costs still require current review.

The internal route is the decisive comparison. It replaces all three purchases, preserves the existing contracts and exposes the resulting workload concentration. If the club's actual budget cannot support the preferred terms, that is the plan it must evaluate. An unfilled shopping allowance is not a fourth, magically complete roster.

The payroll begins with a corrected option decision

The five retained contract allocations total approximately $50.786 million. That includes Severino's exercised $22 million option, Soderstrom at $6.429 million, Rooker at $14 million, Wilson at $2.929 million and Butler at $5.429 million. Allocations include relevant prorated bonuses and differ from both tax AAV and the timing of cash payments.

RosterResource's displayed 2027 headline was approximately $44.836 million at the saved check. Its aggregate omitted Severino's exercised salary. The player row and current option evidence establish that the $22 million belongs in this plan. The headline also does not complete the pre-arbitration roster pool. Treating that subtotal as the full payroll would materially understate the cost of the existing organization.

The four arbitration estimates total $15.3 million: $8.7 million for Langeliers, $1.4 million for Medina, $2.9 million for Gelof and $2.3 million for Harris. These are unsigned estimates. The plan does not assume non-tender savings while continuing to assign the same player's innings or plate appearances.

Keep cash, allocation and tax concepts separate

The budget adds the $2 million McNeil and $750,000 Springs buyouts, then deducts the source's $2 million 2027 Mets credit from the McNeil trade. The earlier $5.75 million credit is not repeated. Actual payment timing and settlement treatment require confirmation. A separate $20-24 million pool covers pre-arbitration players, minor-league roster costs and callups without pretending a new minimum salary or complete future roster is already settled.

The resulting existing-roster allocation is $86.84-90.84 million before new purchases. Benefits, tax and uncertain cash timing are outside that figure. The 2026 RosterResource estimate of $95.421 million provides historical context, not proof that ownership has authorized any particular 2027 budget. The recommended spending requires an actual club-level resource decision that this independent analysis cannot supply.

The long-term contracts also change shape. The four position-player allocations reach about $38.786 million in 2028, before arbitration and the rest of the roster. Wilson's seven-year agreement runs through 2032 with a 2033 option; Soderstrom's also extends through 2032. Butler and Rooker have their own later option structures. The current low annual salaries of some young players are not permanent savings available to spend repeatedly.

Three plans, three different burdens

Plan A adds Mahle at $14-16 million annually, Soroka at $8-10 million, Heim at $2-3 million and the separate $6-8 million reserve. Annual additions are $30-37 million, and new commitments plus the first-year reserve total $44-53 million. The total player-allocation envelope is $116.84-127.84 million. The reserve has no statistical production attached to it.

Plan B substitutes Martinez for Mahle. Annual additions fall to $29-36 million and commitments to $42-51 million, producing $115.84-126.84 million in total allocation. Soroka and Heim remain. The ten additional Martinez innings replace ten Lopez innings. This is a genuine alternative roster, with a different pitching profile, not a fourth starter purchased on top of Plan A.

Plan C retains only the $6-8 million reserve, for $92.84-98.84 million in total allocation. It assigns Mahle's and Soroka's starts to organizational pitchers and Heim's catching work to Serven and Lavastida. It does not assume free high-quality replacements. The financial savings come with a larger dependence on uncertain development and recovery.

At every price ceiling the club should be willing to walk away. A qualifying offer, unexpected compensation cost, medical finding, more expensive guarantee or unavailable roster place can change the preference. The correct response is to rebuild the named alternative and its cost, not quietly raise the total while preserving the original recommendation's headline.

Every batting and defensive assignment has an owner

The season model assigns 6,200 plate appearances across a rotating group. It is not an Opening Day roster with twenty hitters active simultaneously. The principal group leaves room for a second catcher, a defensive outfielder and infield coverage. Serven, Buelvas and other depth candidates enter through actual selections, options or replacements rather than occupying imaginary extra active-roster places.

The defensive budget assigns 162 starts at each position. Kurtz has 130 at first base, Wilson 95 at shortstop and Gelof 120 at second. The shorter Wilson allocation reflects the need for recovery and coverage, not a conclusion that his recent plus-9 OAA is unimportant. Williams, Hernaiz and Walton cover the remaining shortstop starts. No individual is assigned more than 162 combined starts.

The crowded corner and designated-hitter group is a reason to resist an additional bat without a clear displacement plan. Rooker has 105 designated-hitter starts. Soderstrom moves among left field, first base and DH. Muncy and White have limited DH work as well as third-base opportunities. Adding another regular would reduce one or more of those assignments, and the club should identify whose development or production it is choosing to replace.

The innings balance without counting swing pitchers twice

The preferred rotation supplies 162 starts and 855 innings. Mahle and Soroka contribute 275; Ginn, Severino and Lopez another 365. Jump, Perkins, Arnold and Morris cover the remaining 215. The purchased innings reduce the need to force every young pitcher into a full-season rotation job immediately.

The relief budget supplies 585 innings, bringing the planning total to 1,440. Perkins has 60 starter innings and 35 relief innings, for 95 combined. Morris has 20 and 25, for 45 combined. Basso and Barnett initially work in relief, then take starting assignments in the internal alternative. Their combined workloads are checked across both roles.

The 1,440-inning figure is a planning convention. The actual 2026 staff threw 1,430, reflecting how completed games ended. The model is not claiming that every future game lasts exactly nine defensive innings. Its purpose is to prevent a roster proposal from assigning a full rotation and then forgetting the relief burden or counting the same pitcher twice.

Failed signings and failed recoveries have different consequences

Without Mahle, Lopez adds six starts and 35 innings, Jump eight and 40, Perkins eight and 40, and Morris six and 35. Without Soroka, Arnold adds ten starts and 50 innings, Basso eight and 40, and Barnett six and 35. Combined, the internal plan still accounts for 162 starts and 1,440 total innings. Its arithmetic is complete; its readiness is less secure.

The combined loss of Ginn and Severino after the no-acquisition choice is a severe stress test. It removes another 44 starts and 235 innings. The named replacement branch pushes Lopez, Jump, Perkins, Morris, Arnold, Basso and Barnett harder and introduces Nett for six starts and 35 innings. Nett's recent walk rate makes that a conspicuously weak fallback. The table shows why the club should not describe the internal route as equivalent insurance.

The hitter branches are also explicit. A missing Rooker shifts 450 plate appearances and 105 DH starts to Cortes, Soderstrom, Kurtz and White. A missing Wilson moves shortstop work to Williams, Hernaiz and Walton. Soderstrom and Muncy have their own named replacements. These are individual branches; simultaneous absences would require a combined allocation because the same backups cannot perform overlapping jobs without limit.

The 40-name roster creates another concrete constraint. Three proposed signings and later selections require actual corresponding places. Walton, Cortes and lower-leverage pitching depth are candidates for a roster-priority review, not assumed trade value or automatic removals. No option availability, outright acceptance or injured-list exemption is invented. The club must complete the corresponding legal roster transactions before executing this acquisition plan.

A smaller deficit still leaves a demanding climb

Holding offense at 699 runs while reducing runs allowed by 80 produces a minus-158 margin. Scoring 40 more and allowing 100 fewer still leaves minus-98. Even a 60-run offensive improvement paired with 160 fewer allowed leaves minus-18. These arithmetic examples explain why the recommendation focuses on a broad prevention improvement rather than a promise that two signings solve a 238-run deficit.

The simple run-ratio illustration uses 162 times runs scored squared divided by the sum of runs scored squared and runs allowed squared. It is a descriptive comparison, not a calibrated projection or a playoff probability. It does not incorporate schedule, injuries, sequencing, park adjustments or future roster changes. Its useful message is the size of the improvement required.

The strongest objection to the preferred plan is that spending $30-37 million more may still leave a losing club. That is a serious possibility. The case for spending rests on buying enough credible innings to evaluate and support a young lineup, while avoiding longer or more expensive commitments than the identified jobs warrant. If the current medical review undermines those workloads, the money should remain uncommitted until a better alternative is defined.

The recommendation is therefore specific: correct the existing payroll, resolve the major recovery questions, pursue Mahle and Soroka within the stated ceilings, and fill the second catching job modestly. Keep the young hitters' assignments competitive. Review command and defensive deployment early. Do not spend a prospect's hoped-for future or an injured player's hoped-for return before the evidence supports it.

Player register, definitions and sources

The major-roster table is a November 3 snapshot. The research register separately preserves the identities, transactions and classifications of current players, organizational prospects, departed contributors and proposed external acquisitions. Free-agent transaction records take precedence over a stale current-team field. Administrative activation is recorded separately from medical readiness.

Club batting and pitching tables use Athletics-only completed 2026 regular-season samples. Candidate, trend, expected-statistic and handedness tables use the stated full MLB season where available. Minor-league levels remain separate. Baseball innings notation records outs: 138.1 means 138 innings and one out, not 138.1 decimal innings. No postseason performance is blended into the regular-season analysis.

Outs Above Average measures range within its stated opportunities. Framing and total catching value overlap and are not added. Expected batting statistics and xERA describe observed contact and outcomes; they do not supply forecasts or diagnoses. Contract allocations, annual additions, multiyear commitments, unsigned arbitration estimates and cash-payment timing are distinct throughout the financial analysis.
