The Athletics announced that outfielder Brent Rooker has been placed on the 10-day injured list due to a costochondral cartilage injury. Infielder/outfielder Max Schuemann was selected to take Rooker’s place on the active roster. To open a spot for Schuemann on the 40-man, right-hander Luis Medina was transferred to the 60-day injured list.
Rooker was removed from Sunday’s game to due abdominal soreness, per Martín Gallegos of MLB.com, and hasn’t played since. Costochondral cartilage is connected to the ribs, which tracks with his reported soreness. The club has not provided any timeline for Rooker’s expected absence.
He had a late-bloomer breakout last year at the age of 28, hitting 30 homers for the A’s tough also striking out at a 32.7% clip. He played in eight games this year, starting in right field twice but mostly serving as the designated hitter. His absence will mean the club can rotate various guys through the DH slot and give plate appearances to their young and developing hitters.
It will also allow Schuemann to make it to the majors for the first time in his career, just a couple of months ahead of his 27th birthday, which is in June. A 20th-round selection of the A’s in the 2018 draft, Schuemann didn’t get a lot of attention from prospect evaluators until a breakout season in 2021.
That year, he went from High-A to Double-A to Triple-A, playing 119 games between those three levels. He paired a 10.1% walk rate with a 19.6% strikeout rate and slashed .271/.372/.388 for a wRC+ of 111. He also stole 52 bases in 57 tries and bounced around to various infield and outfield positions.
Going into 2022, Baseball America ranked him the #27 prospect in the system while FanGraphs gave him an honorable mention. That year, he continued to get on base at a decent clip and steal bases at the Double-A level, but he struck out in 39% of his Triple-A appearances. That was in a small sample of 41 trips to the plate over 11 games, but it perhaps suggested he was overmatched at the top level of the minors.
But Schuemann continued to improve in 2023. He finally got an extended stretch of Triple-A playing time, 433 plate appearances in 103 games, and responded well. He only hit nine home runs but drew walks at a 14.3% rate while keeping his strikeouts down to a 20.1% clip. He slashed .277/.402/.429 for a wRC+ of 109 while stealing 20 bases in 29 tries.
Per Melissa Lockard of The Athletic, Schuemann went to the Dominican Republic for some winter ball a few months back but was hit in the head with a pitch in his first game, then sat out the rest of the season. Whatever effects there were from that HBP seemed to have passed by the spring, as he hit .294/.405/.382 during Cactus League play.
During his minor league career, Schuemann has played all four infield positions and all three outfield spots. He’ll presumably plug into that roll for the big league club, bouncing all around the diamond as needed while the rebuilding A’s audition their young players for roles in the future of the club.
As for Medina, he was diagnosed with a Grade 2 sprain of the medial collateral ligament in his right knee in early March. His timeline isn’t clear but he hasn’t yet begun a rehab assignment and the club evidently doesn’t expect him back soon. This transfer means he will be eligible to be activated before late May.
