One day after he was placed on the injured list with forearm tightness, New York Yankees right-hander Clark Schmidt is expected to undergo Tommy John surgery.

Yankees manager Aaron Boone told reporters Saturday afternoon that Schmidt has a tear in the ulnar collateral ligament of his right elbow.

Schmidt, 29, had an MRI exam Friday after being removed from Thursday's game at Toronto after three innings. He allowed three runs on four hits and two walks with one strikeout in the 8-5 loss.

He is 4-4 with a 3.32 ERA through 14 starts. He has struck out 73 batters and walked 30 in 78 2/3 innings.

Schmidt is 23-24 with a 3.82 ERA in 97 career games (67 starts) since making his debut with the Yankees in 2020.

New York also added right-hander Scott Effross and left-hander Jayvien Sandridge to the active roster on Friday.
