The Yankees have upgraded their bench and added some outfield depth, announcing Tuesday that they’ve acquired outfielder Austin Slater from the White Sox. The Yankees are sending minor league right-hander Gage Ziehl back to Chicago in return. It’s a one-for-one swap.
Slater, 32, is a reserve outfielder who’s played all three spots and posted good numbers against left-handed pitching — both in 2025 and throughout his nine-year career in the majors. He’s hitting .236/.299/.423 in 135 plate appearances this year, including .261/.338/.552 versus left-handers. In 1006 career plate appearances versus lefties, the righty-swinging Slater is a .270/.362/.436 hitter.
Slater is playing the season on a one-year, $1.75MM deal, though he’s already tacked on $100K worth of incentives based on games played and plate appearances. He could feasibly tack on another $175K by reaching 75 games played and 200 plate appearances. He’ll be a free agent at season’s end.
Though he’s not likely to step into an everyday role, Slater is an affordable means of complementing switch-hitting left fielder Jasson Dominguez, who’s slashing .284/.354/.456 versus right-handed pitching but just .207/.286/.299 versus left-handed opponents. Much the same way that the Yankees acquired Amed Rosario to platoon with new third baseman Ryan McMahon, Slater can share time with Dominguez moving forward.
The Yankees are currently without MVP candidate Aaron Judge, who was recently placed on the injured list due to a forearm strain. A precise timetable for a return remains unclear, but it’s expected Judge will be limited to DH work when he initially returns. Dominguez, Trent Grisham and Cody Bellinger will be the primary outfield trio while Judge is on the mend. Grisham, like Dominguez, struggles against left-handed pitching.
Ziehl, 22, was the Yankees’ fourth-round pick in 2024. He’s spent the bulk of the year in A-ball but was just bumped up to Double-A. The Miami product has posted a combined 4.15 ERA with a 20.2% strikeout rate and 4% walk rate in 86 1/3 innings. Baseball America ranked Ziehl 18th among Yankees prospects on their midseason update of the system just last week. He’s a three-pitch starter whose fastball can climb to 97 mph. Ziehl pairs that pitch with a slider and changeup that both draw average or better grades.
