ST. PETERSBURG -- Blue Jays left fielder Curtis Granderson said he's not certain what happened, but he wound up with right hamstring tightness and was forced to leave Friday night's 6-2 loss against the Rays after the first inning at Tropicana Field.
Granderson smacked a leadoff double, advanced to third on Yangervis Solarte's sacrifice fly, then scored on Teoscar Hernandez's sacrifice fly. But when Granderson went to his position in the first, he said "something didn't feel quite right.''
"We don't think it's a big deal," Blue Jays manager John Gibbons said. "It just tightened up on him."

Granderson told Gibbons of the discomfort when he came to the dugout. 
"He [Gibbons] just said, 'Let's get you out of there,'" said Granderson, who was replaced by Dalton Pompey in left field. "I felt good on the double. Felt good tagging up. Felt good scoring. But when I went to play defense, something wasn't right.
"I got some treatment. The range of motion is good. No MRI needed. I think it's the best possible outcome, but let's see how it feels after I sleep and come in here [Saturday].'"
Granderson said it's possible he could sit out the remainder of the series, take a Monday off-day and return Tuesday at home against the Mariners.
"They liked the location of it [the hamstring tightness] … not too high, not too low," Granderson said. "It's just a precaution. I don't think it is [serious]. We're just being careful."
