Longoria to have MRI on Wednesday
In the seventh inning, Gabe Gross pinch hit for Longoria, who was the designated hitter because of a sore throwing arm. Longoria was hurt running out a grounder during the sixth.
"It grabbed on me a couple of steps after the base," Longoria said. "I think it's more of a precautionary thing than anything. I got on the bike after, felt fine, just had a little bit of trouble keeping it loose. It was better to get myself out in that situation and not prolong anything and hurt it any more."
Longoria will undergo an MRI exam Wednesday.
"I hope it is good, and it may be good by tomorrow," Tampa Bay manager Joe Maddon said. "I just don't know yet."
The 2008 AL Rookie of the Year has 13 homers and 55 RBIs this season.
"It's probably just a day-to-day thing," Longoria said. "I think the telltale thing's going to be tomorrow, how it feels when I wake up in the morning. I didn't feel a pop, I didn't feel a pull. I think if it was something serious, I would be feeling it right now a lot more than I am."
