The Athletics placed right-hander Luis Severino on the 15-day injured list on Saturday with a right shoulder strain.
In a corresponding move, the club recalled right-hander Michael Kelly from Triple-A Las Vegas.
Severino underwent tests on Saturday, one day after he exited his start against the New York Yankees on Friday after throwing only 23 pitches.
Severino was warming up for the start of the second inning when he suddenly walked to the back of the mound and looked toward the dugout, prompting catcher
Shea Langeliers to signal to the dugout. Severino left the game following a brief discussion with a trainer and manager Mark Kotsay.
After the Athletics' 8-2 loss, Severino said he had felt shoulder tightness since facing the Los Angeles Angels on May 21.
The 32-year-old has posted a 4.16 ERA, 1.468 WHIP and 65 strikeouts with a 2-6 record in 12 starts this season. The former All-Star has been more effective on the road, recording a 3.38 ERA.
Last season, Severino's home/away splits were jarring. He had a 6.01 home ERA and 3.02 away ERA.
Kelly is a 33-year-old veteran, who has appeared in 92 career games with the Philadelphia Phillies (2022), Cleveland Guardians (2023), and Athletics. He proved to be an effective bullpen option for the Athletics last season, recording a 3.18 ERA in 42 appearances.
Also, the A's sent third baseman Max Muncy (hand) on a rehab assignment to Triple-A Las Vegas. He was hit by a pitch in a game against the Texas Rangers on April 13 and initially played through the injury until a nondisplaced fracture was discovered nearly two weeks later.
