Ramirez first felt the tightness in the sixth inning of Sunday's game against the Cardinals, manager Mike Quade said. He did not know if a specific play caused the quad to tighten up.
"I think he'll be fine," Quade said. "We'll see how it is tomorrow. I want to see if he can give me an at-bat tomorrow if I need it."
Ramirez, who led the Major Leagues with nine home runs in the month of July, has been hitless in his last five games, going 0-for-17 in that stretch. Quade said the slump didn't affect the decision to keep Ramirez out of the game.
"It's always tough when you've got a guy that hot and [then] he goes for a 1-for-10 or 12," Quade said. "You don't think it's going to last very long."
