The White Sox have re-signed right-hander Lucas Sims to a new minor league contract, according to 670 The Score’s Bruce Levine.  Sims was released after exercising an opt-out clause in his previous minors deal with the Sox two days ago, but he has quickly rejoined the fold and will even pitch in tonight’s Spring Training game against the Mariners.

A veteran of nine MLB seasons, Sims didn’t see much big league action in 2025, as he was rocked to the tune of a 13.86 ERA over 12 1/3 innings out of the Nationals bullpen.  Though Sims signed a one-year, $3MM free agent deal with Washington last winter, his struggles were so extreme that the Nats released him in May.  Sims caught on with the Phillies on a minors deal but didn’t perform well at Triple-A Lehigh Valley, delivering a 5.56 ERA across 34 innings.

Control has always been an issue for Sims, but things reached a point of absurdity last year when he issued 43 walks (against 49 strikeouts) over his 46 1/3 total innings at the Major League and Triple-A levels, as well eight wild pitches and 16 hit batters.  Sims issued three free passes during his five innings of Cactus League work with the White Sox this spring, though he’d also recorded seven strikeouts in those five scoreless frames.

This lack of command has inevitably led to volatility in Sims’ results, but he has always been able to miss bats.  At his best, Sims was able to overcome his control problems to deliver some quality results during his days in the Reds, including a 3.10 ERA across 61 innings.  Sims appears to be ticketed for Triple-A Charlotte to see if he can finally harness his control at least enough to manage a return to the majors, and the White Sox could turn to Sims at some point if a need develops in their bullpen.
