TORONTO -- Right hamstring soreness prompted an early exit for Kole Calhoun in the third inning of the Angels' 11-10 loss to the Blue Jays on Sunday afternoon at Rogers Centre. He will undergo an MRI exam on Monday in Southern California, the club announced.
"I'm definitely concerned," Calhoun said. "Tomorrow is going to tell us a lot more. We don't really know anything other than it's sore. The MRI will definitely show us."
Calhoun reached on an error to load the bases for the Angels in the third, but he said he felt his hamstring tighten while running to first.
"When I hit that ground ball, coming out of the box, I just kind of felt that my hamstring got a little tight and it grabbed," Calhoun said. "It felt more like a cramp than anything."
Calhoun advanced from first to third on Andrelton Simmons' two-run double, but he continued to feel discomfort in his leg. Shortly after he reached third, trainer Adam Nevala came out to check on Calhoun, who subsequently left the game.
"I knew I couldn't really get after it," Calhoun said. "I wasn't helping the team."
Shane Robinson replaced Calhoun on the basepaths and stayed in to play right field for the rest of the game.
Calhoun also ran into the right-field wall while attempting to make a catch on Kevin Pillar's fly ball that went foul in the second inning, but he said he didn't think his hamstring malady was related to that play. The 29-year-old outfielder ended up turning a nifty double play to end the inning, snagging a liner from Rob Refsnyder and then throwing to Luis Valbuena to double up Pillar at first base.
Calhoun is batting .231 with a .677 OPS, 13 home runs and 45 RBIs over 102 games this season. He said he has never dealt with a serious hamstring injury before.
"I've dealt with some things that going through a season you deal with, but nothing that's kept me off the field," Calhoun said. "I'm hoping this one won't either. But we'll see tomorrow."
