NEW YORK -- In the bottom of the fourth inning of the Yankees' 11-1 loss to the Red Sox on Saturday night, catcher Chris Stewart hit a sacrifice fly to center to drive in his ballclub's only run. In the top of the fifth, Austin Romine replaced him behind the plate.
Stewart had left the game with dehydration, and manager Joe Girardi said after the game that the backstop felt lightheaded and he thought it was best to get him out of the game.
"I kind of just felt absolutely fatigued. My body was just weak," Stewart said. "I've never really had that feeling out there before. Kind of took me by surprise."
Girardi said Stewart underwent tests after the game and "checked out OK." Stewart didn't undergo any IV treatment, but he said he did drink a lot of Gatorade and water.
Stewart had started five of the past six games at catcher, and he's started 31 of the team's 55 games this year. He's batting .262 with three home runs and 11 RBIs.
"Hopefully I get a good night's sleep, get some fluids in me," Stewart said. "I'll be back tomorrow."
