Right-hander Luis Severino exited the Athletics' Friday game against the New York Yankees in West Sacramento, Calif., before the top of the second inning due to an undisclosed injury.

Severino, 32, was warming up 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.

He was replaced by left-hander Jose Suarez.

Severino was initially scheduled to start against the Seattle Mariners on Tuesday, but his start was pushed back. The initial reasoning was that the A's wanted left-handers to start against the Mariners.

Severino gave up four runs -- all unearned -- in the first inning due to a throwing error by first baseman Nick Kurtz. Aaron Judge had an RBI single, and Paul Goldschmidt drilled a three-run homer.

Severino pitched for the Yankees from 2015-23, and the right-hander had been treated rudely by his former teammates entering Friday, compiling an 0-2 record and a 10.66 ERA in three starts. He is in his second season with the Athletics after spending 2024 with the New York Mets.

Through 12 starts this year, Severino has a 4.16 ERA.
