White Sox To Call Up David Sandlin For MLB Debut

The White Sox are planning to promote right-hander David Sandlin, reports Elijah Evans of Just Baseball and Future Sox. The 25-year-old is already on Chicago’s 40-man, but the team will need to make space for Sandlin on the active roster. Confirming the move, James Fegan of Sox Machine noted that Sandlin is likely going to start for the White Sox, although it’s not entirely clear how he would fit into the rotation. It’s possible he’s only coming up to make a spot start, considering Chicago is in the midst of playing 13 games without a day off.

Sandlin, 25, began his professional career with the Royals in 2022, and Kansas City traded him to Boston in 2024. The Red Sox then dealt the righty to the White Sox this past winter – along with Jordan Hicks, two players to be named later, and cash – in exchange for Gage Ziehl. Sandlin was the prize of the deal for the White Sox, who were willing to take on most of Hicks’ remaining salary to acquire him. In fact, at the time of the trade, general manager Chris Getz even described Sandlin as “essentially” part of the return for Luis Robert Jr., since the GM was able to use some of the money he saved by trading Robert (and his $20MM salary) to pay for Hicks, and, therefore, to secure Sandlin. Getz went on to say that Sandlin would compete for a spot on Chicago’s Opening Day roster, praising his “mid-rotation” arsenal and stuff. “He’s got a chance to really impact our starting rotation this year,” Getz explained (per MLB.com’s Scott Merkin).

Sandlin didn’t end up pitching in big league spring training. Back and forearm soreness (per Fegan) forced him to start the season on the minor league injured list instead. However, from his first rehab start at High-A Winston-Salem to his latest outing for Triple-A Charlotte, he has been nothing short of electric. Leading with a four-seam fastball that flirts with triple digits, he’s given up just 12 hits in 16 1/3 innings, striking out 26. While his walk rate is high, he hasn’t let the free passes lead to much damage; Sandlin didn’t allow an earned run until his most recent start.

Most prospect evaluators roughly agree with Getz’s assessment of Sandlin. He has No. 3 or 4 starter upside, but he needs to improve his control and hone the rest of his arsenal (besides that high-velocity heater) if he’s going to get there. While his results this season have been promising, his Triple-A numbers from 2025 demonstrate why there’s cause for concern. In his first 23.2 innings at the highest minor league level, he walked 13 batters, beaned two more, and gave up 35 hits en route to a 7.61 ERA and 5.27 FIP.
