SEATTLE — Orioles catcher Matt Wieters abruptly left Tuesday night's game against the Seattle Mariners in the third inning with what the team called a right hamstring strain.
Wieters exited the game at the same time as when Orioles manager Buck Showalter pulled struggling starter Chris Tillman with one out in the third inning.
On the previous play, Wieters fielded Mark Trumbo's grounder in front of the mound and threw to first base.
Caleb Joseph replaced Wieters behind the plate.
Wieters is coming off Tommy John surgery performed in June 2014, and has caught on consecutive days just once since returning.
A pending free agent, Wieters is hitting .278 with five homers and 17 RBIs in 46 games this season.
Tillman, who allowed five runs on eight hits over 2 1/3 innings, was pelted in the right arm by a Robinson Cano comebacker in the first, but remained in the game after being examined by trainer Brian Ebel and throwing a few warmup pitches.
The Orioles were up 2-1 at the time, but Tillman allowed a three-run homer to Trumbo two batters later and trailed 5-2 when he left the game.
Tillman was making his first start since suffering a left ankle sprain that forced him to miss one turn in the Orioles rotation.
