Give the White Sox a sturdier rotation

The verdict

The White Sox scored 129 more runs in 2026 than they did in 2025. They allowed only 22 fewer. The offense drove a 24-win improvement, and much of that offense remains under control. The next useful investment is a starting pitcher who can keep the bullpen from carrying another 766 innings. Chicago should protect the young lineup's opportunities while buying enough pitching to make its recovery more durable.

Our preferred plan pursues Nick Martinez for two years and $26 million to $30 million, retains Sean Newcomb for two years and $12 million to $16 million, retains Trevor Richards for one year and $3 million to $5 million, and brings back Randal Grichuk for one year and $6 million to $8 million. A separate $6 million to $8 million reserve covers depth and in-season needs. Those are Stadium & Street negotiating limits, not reported offers or an assurance that these players will sign.

The package adds $34 million to $44 million in annual allocation to an existing-roster envelope of $97.25 million to $101.25 million. The resulting $131.25 million to $145.25 million plan does not assume a healthy Luis Castillo, a recovered Drew Thorpe or salary relief from moving Andrew Benintendi. Those possibilities can improve the roster, but they cannot be spent before they exist.

The strongest objection is that a team with several young pitchers should use its money elsewhere and let those arms grow. That is a reasonable development argument. The difficulty is the combination of short major-league track records, recoveries and the loss of three pitchers who supplied substantial 2026 innings. The preferred plan preserves opportunities for Noah Schultz, Hagen Smith, David Sandlin and Tanner McDougal while reducing the amount of immediate success required from all of them at once.

What actually changed

Chicago went from 41-121 in 2024 to 60-102 in 2025 and 84-78 in 2026. Its run margin moved from minus-306 to minus-95 to plus-56. The latest improvement was much more than a handful of close-game victories: 776 runs scored ranked fifth in the majors, while a 4.12 ERA ranked 14th. Those rankings describe different strengths.

The White Sox then won the first two games of their Division Series against Cleveland before losing the last three. That result identifies the season's endpoint. It is not enough evidence to declare a psychological defect or to justify dismantling the roster. A five-game series should sharpen questions about deployment and depth without erasing 162 games of development.

The larger challenge is sustaining an offense with several young contributors whose actual results and expected contact statistics do not all tell the same story. Chicago has earned a more ambitious plan. It has not earned permission to assume that every improvement will repeat.

The roster has already moved

The current roster contains 39 players. On November 2, Chicago claimed Graham Pauley and outrighted Ky Bush and Junior Perez. Pauley's individual player record still carried Miami, but the current White Sox roster and the club's announcement establish the move. This analysis uses the transaction, not the stale affiliation label.

Fedde, Newcomb, Richards and Grichuk are free agents. They remain in the historical tables because their work helped produce the 2026 result, but they cannot also be treated as contracted 2027 contributors. Any retained innings or plate appearances for them require a new agreement.

Jacob Gonzalez is in Pittsburgh's organization. Seranthony Dominguez's White Sox innings also belong to the completed season, although a retained bonus expense remains in the financial bridge. These distinctions prevent two common planning errors: counting a departed player as depth and removing a financial obligation merely because the player has left.

The offensive foundation

Miguel Vargas supplied 704 plate appearances, 33 home runs and 101 walks. Munetaka Murakami added 35 home runs and 92 walks in 553 plate appearances. Chicago now has two substantial sources of power and patience without needing to acquire another everyday first baseman. Their defensive limitations influence where they play, not whether their bats belong in the lineup.

Chase Meidroth, Sam Antonacci and Tristan Peters added different forms of value. Meidroth reached 643 plate appearances, Antonacci produced a .766 OPS in 557, and Peters delivered a .774 OPS in 491. A useful offseason should preserve those distinctions rather than turn the lineup into a search for nine home-run hitters.

Colson Montgomery's 31 home runs came with 227 strikeouts in 638 plate appearances. His range at shortstop strengthens his case for continued development, but the strikeout total leaves little room for weak contact or poor sequencing. The task is to help him make more productive contact while retaining the power, not to celebrate the home-run total in isolation.

Contact quality and regression

Vargas's .378 expected wOBA exceeded his .363 actual mark. Murakami's .351 expected figure closely matched his .356 actual result, and Antonacci's .348 expected figure matched his .345 actual result. Those comparisons support important parts of the offensive improvement. They do not assign each player an exact 2027 outcome.

Meidroth and Peters require more caution. Their expected figures were below their actual production. That does not mean their seasons were fraudulent or that a decline is inevitable. It means the budget should not assume that every retained hitter will improve simply because he is young. Braden Montgomery offers a different case: his expected batting results were somewhat stronger than his actual production, leaving a plausible development route without an expensive replacement.

The three-year table also shows where comparison is impossible. Some of the most important hitters have little or no earlier major-league record. A missing season is not zero ability, but it reduces confidence in a narrow forecast. Chicago should use ranges and preserve alternatives rather than attach a single projection to each unfamiliar name.

Matchups without a platoon trap

Grichuk produced a .926 OPS in 247 White Sox plate appearances, but his full major-league season was 280 plate appearances with an .880 OPS. The smaller Chicago sample is not the correct basis for assuming everyday production. We assign him 260 plate appearances in a limited corner role and compare the full-season handedness splits below.

A short split can suggest a deployment choice without settling a player's long-term ability. Braden Montgomery needs meaningful work against major-league pitching, including difficult matchups. Grichuk can protect selected starts and supply a right-handed option without taking over the position. If his price or desired role exceeds this limited assignment, the club should keep the younger players' opportunities and use the internal alternative.

Benintendi's salary should not determine his batting order position or defensive workload. The contract is already a cost. The decision now is which matchups and assignments make the remaining plate appearances most useful. A reduced role can be justified without assuming that another club will absorb the contract.

Preserve the range, repair the corners

Meidroth recorded plus-10 Outs Above Average, Colson Montgomery plus-12 and Peters plus-11. Vargas was minus-8 and Antonacci minus-9. Those results suggest a roster with valuable range up the middle and more difficult decisions at the corners. They are not interchangeable measures of every defensive skill, and a single season should not be treated as a permanent label.

The preferred alignment keeps Colson at shortstop, Meidroth primarily at second and Peters in center. Vargas receives substantial third-base work because his bat is central to the offense, with some first-base and designated-hitter assignments. Antonacci remains a left fielder with a real second-base reserve role, supported by his 153 innings there in 2026.

Brenton Doyle supplies a second demonstrated center fielder. We do not give him unverified right-field starts merely to make a spreadsheet balance. The main defensive map uses Braden Montgomery, Grichuk and Peters in right; any expanded corner role for Doyle needs actual preparation and verification.

Four catchers, one development problem

Teel, Quero, Romo and Bart are controlled catching options. Their 2026 records do not support treating any one of them as a complete solution. Quero's .541 OPS and Romo's .534 OPS came in limited samples, while Teel managed a .697 OPS in 144 plate appearances. The club needs better offense without discarding the defensive and developmental differences among them.

The framing table shows different signals from Romo and the other catchers. A missing qualified overall catching value is not proof of zero value. Framing, blocking, throwing, game preparation and workload all matter, and the available public measures cover only part of that job.

Bart returned after a left-hand fracture, and Teel returned in September after an ankle injury. Their administrative activation is useful evidence of a return, not a medical guarantee for the next season. The 900 combined plate appearances assigned to the four catchers include designated-hitter work and changing roster availability across the year. This is not a recommendation to carry four catchers on every active roster.

Why the rotation needs help

White Sox starters supplied 674 2/3 innings with a 4.60 ERA. Relievers supplied 766 innings with a 3.70 ERA. The classification includes openers and flexible roles, so the gap is not simply a list of starters who failed to finish five innings. It nevertheless shows how much of the season depended on pitchers working outside conventional starting assignments.

Sean Burke was the clearest foundation: 172 1/3 innings, a 3.34 ERA, 185 strikeouts and 62 walks. Davis Martin supplied 146 innings with a 3.95 ERA. Anthony Kay supplied 158 innings with a 4.44 ERA, while his expected ERA was higher. That is a workable returning group, but it leaves both quality and volume to be supplied behind it.

The preferred workload asks those three for 445 combined starter innings. It gives Schultz 100, Sandlin 60, Cannon 40 and McDougal 40. The remaining 165 belong to the proposed Martinez acquisition. This approach creates actual jobs for developing pitchers while avoiding a plan in which every open start requires a breakthrough.

Recovery is a branch, not the foundation

Castillo's 2026 White Sox results were poor, and he went on the injured list in September with shoulder impingement. His salary remains in the base budget. His innings do not appear in the main rotation. A separately balanced return scenario gives him 20 starts and 100 innings only after health, effectiveness and workload are established.

Thorpe's official transaction history records Tommy John surgery recovery, a summer rehabilitation progression and a September activation. He threw 29 Triple-A innings with a 2.79 ERA, plus earlier rehabilitation work at lower levels. That is a reason to retain a recovery path, not a reason to budget 150 major-league innings. His conditional branch is eight starts and 40 innings.

Vasil and Berroa receive no opening workload in the main plan. Leasure receives a separate conditional relief branch after his flexor recovery. Murphy returned September 7 after a flexor strain and receives a modest assignment with an explicit replacement if unavailable. These are individual cases, not a single category called healthy because the 60-day injured list was cleared administratively.

Keep the bullpen's useful bulk

Grant Taylor struck out 106 hitters in 84 innings with a 2.25 ERA. Hagen Smith struck out 41 in 28 innings, but also walked 16. Taylor can anchor important innings, while Smith's electric results still require command and workload judgment. Neither should be assigned every difficult inning created by a thin rotation.

Newcomb and Richards are the preferred retentions because Chicago has already demonstrated a need for multi-inning work. Newcomb supplied 90 1/3 White Sox innings. Richards supplied 78 2/3 for Chicago and 83 across his full major-league season. Our assignments of 75 and 65 relief innings are below those completed totals, though they remain contingent on a new deal and a healthy return.

Hicks's 33 walks in 48 innings limit confidence in a high-leverage role despite a more encouraging expected ERA. Hudson, Schweitzer, Davis, Murphy and Brazoban provide depth, but their samples and underlying measures vary. The plan should make those pitchers compete for appropriate roles rather than assume that last year's relief ERA guarantees another strong bullpen.

Compare the actual starter choices

Martinez offers a distinctive combination in this candidate group: 180 innings, a 3.10 ERA and only 26 walks. His expected ERA was 3.98, so the proposal does not pay for a guaranteed repeat of the actual ERA. It pays for demonstrated volume and strike throwing at a two-year limit.

Fedde is the lower-cost alternative. His 141 innings and 3.83 ERA provide a credible retention case, but 52 walks and a 4.79 expected ERA weaken the argument that he solves the same problem at equal quality. Plan B gives him the same 165-inning job for accounting purposes and explicitly requires a workload review. That assignment is an expansion, not evidence that he already performed it.

Mahle is a useful alternative at two years and $28 million to $32 million, adding $1 million annually to the Martinez range. Taillon, Singer, Bieber, Giolito and Littell were examined because a serious analysis needs alternatives. Their 2026 performance, reduced innings or medical issues make them less suitable as the main purchased foundation at this checkpoint. A cheaper contract does not necessarily buy a safer workload.

Repeated targets must earn their place

Martinez appears in several S&S club analyses because a starter with 180 innings and 26 walks addresses a common need. Chicago's job is specific: 30 starts and 165 innings replacing the amount of developmental depth otherwise required from Schultz, Sandlin, Cannon, McDougal and Shane Smith. The same two-year, $26 million to $30 million ceiling used elsewhere is retained here. We do not invent a Chicago discount or assume that all interested clubs can obtain him.

Grichuk's proposed $6 million to $8 million is attached to 260 plate appearances, not an everyday job. That limited assignment is consistent with the need to preserve Braden Montgomery's development. Newcomb and Richards address Chicago's unusually large relief workload; their roles are more directly tied to this roster than adding a familiar late-inning name with no identified innings to replace.

Clarke, Kittredge and Steven Okert are alternative relief candidates. Substituting one for Richards changes both price and workload: each receives 60 innings, with Hudson taking the remaining five. Okert is substantially more expensive than the preferred Richards range and needs a stronger leverage justification. None is funded in addition to the complete preferred package.

These plans are free-agent purchases and retentions. They require no invented trade return or outgoing prospect package. If the club pursues a trade instead, the actual player control, salary, roster space and outgoing talent must be evaluated together. The depth reserve is not a claim on an unnamed star.

The farm is a source of options

Caleb Bonemer hit 19 home runs in Double-A after 18 in High-A, producing a .924 OPS in 317 Double-A plate appearances. He also played center field in Double-A in addition to the left side of the infield. That combination gives Chicago an interesting route to a future opening, but it does not settle which major-league job he is ready to perform.

Roch Cholowsky's 46 High-A plate appearances are far too small a professional sample to build the 2027 roster around. Carlson and Fauske remain development cases. Their presence strengthens the organization's options over time without making a current free-agent or medical problem disappear.

Schultz threw 44 2/3 Triple-A innings in addition to his 74 1/3 in the majors. Hagen Smith threw 58 1/3 Triple-A innings before his major-league work. Those completed workloads provide a more useful starting point than prospect rank alone. McDougal's Triple-A command and very small major-league sample require particular restraint.

Bonemer can earn a 200-plate-appearance branch by taking 100 from Benintendi and 100 from Braden Montgomery, provided his actual defensive role, selection and readiness justify it. That is a competition with named displaced players. It is not a promotion promised before spring training.

Start with the money already committed

The five listed guarantees total $74.25 million on the salary-plus-allocated-bonus basis used here. Castillo, Murakami, Benintendi, Hicks and Kay remain costs before any new acquisition. The credits below are applied once, and retained expenses stay in the model even when the player has departed.

Six arbitration estimates total $15.4 million. Those are published estimates, not agreed salaries. Changes at tender time will change the payroll envelope and may also remove a player's assigned workload. The model does not take a projected salary saving while keeping the same player's innings or plate appearances.

The largest accounting trap is carrying Seattle's 2026 Castillo contribution into 2027. The payroll source lists that amount in the 2026 column only. It is not a recurring discount in this analysis. The Castillo bonus credit, Hicks bonus credit and Boston contribution have separate 2027 entries.

The financial bridge

After the $1.4 million Castillo bonus credit, $4.5 million in Hicks-related credits, $0.5 million retained Dominguez bonus, arbitration estimates, a $1 million Hays buyout and a $12 million to $16 million pre-arbitration and depth allowance, the starting envelope is $97.25 million to $101.25 million.

Kay's potential $2 million buyout belongs to a later option decision, not the current 2027 charge. The earlier Martin Perez buyout also belongs to a different year. Including either again would exaggerate the current cost. Conversely, dropping Benintendi or Castillo from the expense column because their roles are uncertain would understate it.

These figures are planning allocations. They are not a bank-account cash schedule, an official competitive-balance-tax calculation or a claim about what ownership has approved. The club's actual willingness to spend must be established separately from the arithmetic.

Three funded choices

Plan A buys Martinez's starter role, retains Newcomb and Richards for 140 combined relief innings, retains Grichuk for 260 plate appearances and includes the depth reserve. Its $34 million to $44 million annual addition corresponds to $53 million to $67 million in total new commitments, including the reserve. The distinction matters because two of the proposed contracts run for two years.

Plan B replaces Martinez with one year of Fedde at $8 million to $10 million. The rest of the package remains funded. That produces a $126.25 million to $140.25 million annual envelope and $35 million to $47 million in new commitments. It is a cheaper, less reliable version of the same workload structure, not a second roster that quietly keeps Martinez too.

Plan C adds only the $6 million to $8 million reserve. The $103.25 million to $109.25 million total leaves the lineup largely internal and asks the developing pitchers to absorb the missing work. It is financially coherent. Its risk is baseball depth: another setback could force the club to purchase pitching later from a weaker negotiating position.

The branches have prices

Every substitute needs a corresponding deletion. Mahle replaces Martinez. A different reliever replaces Richards. A healthy Castillo replaces assigned internal starts. Grichuk's departure returns plate appearances to the younger outfielders. This is how the plan avoids presenting several attractive names as if they all fit at once.

Current free-agent eligibility and any signing compensation must be checked before an agreement. None of the preferred additions is justified by assuming a particular club will waive a right or that a reported market preference is a completed transaction. A price ceiling is useful only if the club is prepared to choose its alternative when the price is exceeded.

Give every hitter a real job

The preferred plan allocates 6,200 plate appearances. Vargas and the young middle infield remain central. Antonacci and Peters retain substantial opportunities. Murakami occupies first base and designated hitter, while Benintendi's role is reduced without pretending his salary disappears.

This is a full-season workload, including injuries, options, promotions and changing availability. It is not a claim that all 16 hitters belong on the same active roster. Pauley must earn his roster place; if he does not, the model replaces his plate appearances and revises the corner coverage rather than leaving an empty line.

Balance the innings before praising the staff

The preferred rotation covers 162 starts and 850 innings. The relief allocation covers another 590, giving a 1,440-inning planning season. Actual innings will differ with extra innings, shortened games and home losses. The purpose is to expose missing work and conflicting assignments before attaching a win expectation to the roster.

Sandlin, Cannon and McDougal have both starting and relief assignments, but those are added explicitly. Their combined totals remain visible. Taylor's 90 innings and Hagen Smith's 70 also require active workload management rather than a promise that a young arm will repeat a short stretch for six months.

The Castillo and Thorpe return branches cannot be stacked unchanged because they displace some of the same starts. If both become available, a new complete rotation map is required. The internal plan is similarly a coverage test, not evidence that its inexperienced innings will produce the same run prevention as the preferred acquisitions.

Put the defense on the same calendar

The position map below allocates 162 starts at each position and prevents any hitter from being booked for more than 162 total starts. It keeps demonstrated center fielders in center, avoids an assumed Doyle corner conversion and gives the catchers defined designated-hitter opportunities.

The alignment makes the central tradeoff clear. Chicago is retaining Vargas's offense at a defensive cost, limiting Benintendi's field exposure and protecting the young middle-infield combination. Defensive improvement can come from better execution and more suitable deployment without requiring a new player at every weak position.

What improvement would have to accomplish

Chicago's 776 runs scored and 720 allowed produce about 87 wins in a simple squared-run-ratio calculation, compared with the actual 84. That difference is descriptive. It does not establish a bank of wins owed to the next team. The scenarios below show how changes in scoring and prevention interact.

Preventing 30 more runs while preserving the offense offers a plausible route to a stronger team. Losing 40 runs of offense while allowing 30 more would erase the existing margin. This is why the rotation investment and the offensive development plan belong in the same analysis: a few extra starter innings are valuable only if they improve the team's total run picture.

The recommended first move is to establish the actual medical and workload outlook for Castillo, Thorpe and the recovering relievers while negotiating with the preferred starter group. Do not wait for those recoveries to become certain before learning the cost of outside help. Do not sign redundant hitters merely because the offense is easier to market.

The decision and the evidence

The White Sox have a credible young offense and a staff that needs a more dependable distribution of work. Plan A is the best fit at the stated ceilings. Plan B is defensible if Martinez's market moves beyond the limit. Plan C is the honest fallback, with all of its developmental risk left visible.
