Seranthony Domínguez has agreed to a two‑year, $20 million contract with the Chicago White Sox, including a mutual option for a third year at $8 million.

Contract Details and Financial Terms
The agreement guarantees $10 million per season for the first two years. A mutual option for 2027 is set at $8 million, allowing either side to opt‑out based on performance and health. This structure provides flexibility while rewarding Domínguez’s proven track record.

Domínguez’s Performance Highlights
In 2024, Domínguez posted a 2.71 ERA across 71 appearances, striking out 94 batters in 71.2 innings for a K/9 of 11.8—well above the league average. His fastball regularly tops 96 mph, complemented by a sharp slider and deceptive changeup.
2024 Season Stats
- ERA: 2.71
- Innings Pitched: 71.2
- Strikeouts: 94
- K/9: 11.8
- WHIP in high‑leverage situations: 0.92
Impact on White Sox Bullpen
The addition directly addresses Chicago’s late‑inning struggles. The Sox finished 2024 with a league‑worst team ERA of 4.45. Domínguez’s ability to shut down opponents from the seventh inning onward provides an immediate upgrade.
Addressing Late‑Inning Weakness
His veteran presence also offers mentorship for younger arms, helping to stabilize the bullpen while the team evaluates long‑term closer options.
Strategic Fit for Chicago
General Manager Chris Aldridge highlighted Domínguez’s “high strikeout upside” and “pressure‑tested track record” as perfect for the Sox’s competitive vision in 2025 and beyond.
Potential Role and Closer Competition
With closer Liam Hernandez’s 2024 performance under scrutiny, Domínguez is projected to assume ninth‑inning duties by mid‑season and serve as a bridge reliever in high‑leverage situations, freeing left‑handed specialist Matt Keller for specialized matchups.
Division Implications
The strengthened bullpen positions the White Sox to better compete with AL Central rivals such as the Kansas City Royals and Minnesota Twins, potentially converting close‑game losses—of which the Sox had 12 in 2024—into wins.
