The White Sox will install Nick Nastrini back into their rotation, reports Daryl Van Schouwen of the Chicago Sun-Times (X link). Manager Pedro Grifol confirmed after tonight’s win over the Blue Jays that the rookie right-hander will take the ball tomorrow in Toronto, pushing Mike Clevinger back to Thursday’s series opener against the Orioles.
Chicago needed to settle on a new fifth starter after designating Brad Keller for assignment on Sunday. Nastrini and Jonathan Cannon, each of whom made his MLB debut in April, were the likeliest options. Nastrini took two starts for the Sox last month. He worked five innings of two-run ball against the Royals in his debut before surrendering six runs across three frames in a road matchup with the Phillies.
The Sox optioned Nastrini back to Triple-A Charlotte after his start in Philadelphia. Keller drew into the rotation for a couple turns, while Clevinger returned to the majors after his late free agent signing. The Sox quickly decided to move on from the veteran Keller in favor of a look at a younger pitcher.
Nastrini, 24, is a former fourth-round pick of the Dodgers. The Sox acquired him at last summer’s deadline in the Lance Lynn/Joe Kelly deal. Nastrini closed last season in Charlotte, where he has spent the majority of the 2024 campaign. His 5.83 ERA in 29 1/3 Triple-A frames isn’t particularly impressive, but the UCLA product has fanned nearly 27% of batters faced with a serviceable 8.2% walk rate. The longball has been his biggest issue, as Nastrini has allowed nine homers in six starts.
The Sox’s rotation has been one of the league’s worst overall, though it’s not without a few interesting performers. Garrett Crochet tossed six scoreless innings to earn the win tonight. He lowered his season ERA to 3.75 in the process. Crochet has punched out more than 32% of opponents in his first year as a starter.
Erick Fedde has allowed 3.10 earned runs per nine over 10 starts in his return to the majors. That mid-rotation production and his modest $7.5MM salaries through 2025 make him an intriguing trade candidate. Every other pitcher who has made multiple starts — Nastrini, Cannon, Keller, Clevinger, Chris Flexen and Michael Soroka — has an ERA above 5.00.
Chicago will officially recall Nastrini tomorrow. They’ll need to option or designate a pitcher for assignment to comply with the 13-pitcher maximum. It could be one of multiple moves, as the Sox will know in the coming days if Eloy Jiménez requires a stint on the injured list. The hulking DH left tonight’s game with a left hamstring strain.
