Athletics Place Brent Rooker On Injured List

The Athletics announced today that outfielder/designated hitter Brent Rooker has been placed on the 10-day injured list due to an oblique strain. Infielder/outfielder Zack Gelof has been recalled as the corresponding move.

It’s not an especially surprising development. Rooker appeared to injure himself on a swing yesterday, reaching for his side. He was removed from the game with the A’s announcing his issue as right flank discomfort. Gelof was scratched from the Triple-A lineup, which suggested he would likely be called up to take Rooker’s place.

The A’s haven’t announced how long they expect Rooker to be out but obliques can be pesky injuries for baseball players since they play a notable role in rotating the body, which is important for swinging and pitching. Rooker is out to a slow start this year, with a .146/.245/.293 line, but in a small sample of 49 plate appearances. In a much larger sample of 1,839 plate appearances from 2023 to 2025, he hit 99 home runs and slashed .268/.343/.509.

The one benefit for the A’s is greater positional flexibility, as Rooker is usually the designated hitter. They can now use that spot to move guys in and out, lightening their workloads from time to time. Gelof has only played second base in his big league career but has been dabbling with some outfield work lately. The A’s have mostly been using Jeff McNeil at second. He’s the oldest regular position player, so perhaps he will get some more time as the DH.

Gelof has shown power in his big league career but has also been punched out in a third of his plate appearances. He’ll need to get that down to become a viable big leaguer. For what it’s worth, his minor league season has started well. He has only been punched out at a 13% clip in his small sample of 54 trips to the plate, which has helped him produce a monster .366/.519/.732 line. No one should expect him to hit like that in the majors but any improvement in the strikeout department should be a big help.

If the A’s want to try him in the outfield, their current mix includes Tyler Soderstrom, Denzel Clarke, Lawrence Butler and Carlos Cortes. Using Rooker’s vacated DH spot could allow the club to potentially spread some at-bats to that group and Gelof.
