White Sox face rotation overhaul after surprise playoff run, per MLB Trade Rumors

The Chicago White Sox made history in 2026 — and not the kind that involves a record-setting strikeout total, though they managed that too. Per Anthony Franco at MLB Trade Rumors, the club was the first ever to follow three consecutive 100-loss seasons with a playoff berth, knocked out the Houston Astros for their first series win in two decades, and then watched a 2-0 ALDS lead over the Guardians evaporate. Now the front office faces the question every team that overachieves its rebuild timeline eventually has to answer: what does it cost to stop being a pleasant surprise and start being a genuine threat?

What happened

Anthony Franco's offseason outlook at MLB Trade Rumors frames the White Sox's primary offseason task plainly: the rotation needs to be rebuilt. General manager Chris Getz reportedly acknowledged as much at his end-of-season press conference, though as Franco notes, White Sox fans would not have needed the press conference to reach that conclusion. Chicago's starting pitching was the club's weakest link throughout 2026 and had deteriorated to something approaching structural failure by the time the playoffs arrived.

The ALDS exit carried a particular sting. Per Franco's reporting, the White Sox posted an all-time record strikeout total — 21 in a nine-inning shutout — with Gavin Williams and three relievers doing the damage. That is the kind of footnote that follows a franchise into the winter.

Why it matters

The position player core, per Franco's reporting, is considered talented enough that the front office's ambitions are not unreasonable. The question is whether ownership and the front office will be aggressive enough to supplement it with the pitching the roster currently lacks.

Sean Burke was reportedly the only reliable starter by season's end — a significant load for one arm to carry. He had been one of the better pitchers in the American League for much of the summer, per the report, and took on the role of the 2026 White Sox breakout starter, a distinction that had initially appeared destined for Davis Martin. Martin, a Texas Tech product, reportedly ran off a dominant 11-start stretch through May before posting a 5.63 ERA over the remainder of the season. Burke's own performance tailed off somewhat down the stretch, per Franco, though his overall summer was strong enough to anchor whatever the club builds around him next year.

The rotation situation was further complicated by Luis Castillo. Per Posterior Wire reporting from earlier this week, Castillo dealt with a shoulder impingement that landed him on the injured list in September and hampered his late-season performance. Castillo is under contract through 2027 at $22.75MM, with a vesting option for 2028 at 180 innings — a threshold that will require a healthy and durable season to reach. His health this offseason is one of the more consequential open questions on the roster.

The numbers

The White Sox carry $71.25MM in 2027 financial commitments and $73.25MM in total future commitments, per Franco's reporting. The guaranteed contracts on the books include Castillo at $22.75MM through 2027, Munetaka Murakami at $17MM through 2027, Andrew Benintendi at $14.5MM through 2027, Jordan Hicks at $12MM through 2027, and Anthony Kay at $7MM through 2027 (the latter figure includes the buyout of a 2028 mutual option).

The arbitration class adds further payroll considerations. Projected salaries, courtesy of MLBTR contributor Matt Swartz, place Miguel Vargas at $5.4MM, Brenton Doyle at $3.6MM, Joey Bart at $2.9MM, Huascar Brazobán at $1.6MM, Jordan Leasure at $1MM, and Chris Murphy at $900K. Franco identifies Bart, Murphy, and Leasure as non-tender candidates — meaning the club could decline to offer them contracts, making them free agents.

The free agent class departing includes Erick Fedde, Sean Newcomb, Trevor Richards, Randal Grichuk, Jake Rogers, and Tommy Pham.

Where the club stands

The White Sox finished 84-78 (.519), second in the AL Central and one game back in the division race. They enter the offseason on a one-game winning streak and eliminated from the division race — which, given where this franchise was three years ago, is a sentence that would have read as satire.

What we don't know yet

### Will the White Sox pursue starting pitching aggressively this winter?

Getz reportedly said the club will pursue starting pitching this offseason, per Posterior Wire reporting from earlier this week. What that pursuit looks like in practice — whether it means a top-of-market free agent, a trade, or a combination of depth additions — is not yet known. Franco's report does not specify targets, dollar figures, or a timeline for decisions.

Castillo's shoulder health is similarly unresolved. The impingement that sent him to the injured list in September is a known concern; his availability and durability heading into 2027 will shape how the front office approaches the rest of the rotation.

The non-tender decisions on Bart, Murphy, and Leasure have not been made. Franco flags them as candidates, not certainties.

One name worth watching from the broader offseason landscape: NPB right-hander Kona Takahashi is reportedly inclined to pursue MLB opportunities this offseason and is eligible for international free agency, per earlier Posterior Wire reporting. Whether the White Sox would have interest is not reported, but a club with a stated need for starting pitching and a rotation that was, by the end of the year, running on fumes and optimism is at least a logical name to file away.

What to watch

The rotation is the story. Burke is the one established piece; everything around him is either a question mark, a health concern, or a free agent who has already left the building. How aggressively Getz moves — and how much of the $71.25MM in 2027 commitments leaves room for meaningful additions — will define whether this White Sox team consolidates its surprising 2026 or spends another year finding out what it actually is.

The arbitration decisions, particularly on the non-tender candidates, will offer an early read on how the front office is thinking about roster construction. And Castillo's offseason health updates, when they come, will matter more than almost anything else on the ledger — a $22.75MM arm with a shoulder impingement and a 180-inning vesting option is a situation that tends to clarify itself one way or another before spring.

Per Franco, the White Sox have arrived. The hard part is what comes next.
