White Sox Add Huascar Brazobán From Mets, Doubling Up on Deadline Buys

The White Sox weren't done after Castillo. Late Sunday night, Chicago went back to the market for bullpen help.

Quick answer: The Chicago White Sox acquired right-hander Huascar Brazobán from the New York Mets for a package of minor-league arms, a second deadline pickup after Sunday's earlier trade that brought Luis Castillo over from Seattle. Read that deal in full in our White Sox-Castillo breakdown.

The trade details

Athletic and ESPN reporting had the deal finalized late Sunday night into early Monday, ahead of the 6 p.m. ET deadline. New York continues clearing its bullpen of veteran relief pieces as part of a broader sell-off that also sent Freddy Peralta to Tampa Bay the same weekend.

What Chicago is buying

Two trades in one weekend is unusual mid-market activity, and it signals a front office trying to make a real second-half push rather than just checking a box. Brazobán gives the White Sox a proven high-leverage arm: AthX Engine has him at 141.56 fantasy points on the season, tracking to a 197.97 FP pace, numbers that hold up against most setup and closer options who moved this deadline.

He joins a pitching-forward roster that already features Sean Burke (306.29 FP) in the rotation and Grant Taylor in relief, with Miguel Vargas leading the lineup. Adding both a starter and a high-leverage reliever in the same weekend is the kind of stacked buying usually reserved for bigger-market clubs.

What New York is selling, and why

This fits the pattern from the Peralta trade earlier the same day: the Mets are moving established big-league arms for controllable, cost-effective depth as the front office looks past 2026. Brazobán's value was always going to be as a rental piece for a bullpen-needy contender, and Chicago's aggressive buying made it an easy match.

AthX Engine angle

Brazobán's run-prevention and strikeout numbers are already on the books and travel with him. His 141.56 FP season total and 197.97 pace are the baseline heading into high-leverage White Sox innings. Role clarity, whether he closes, sets up, or handles matchup work, will matter more than the uniform change for his week-to-week AthX Engine scoring.
