OAKLAND -- A's outfielder Seth Smith, serving as designated hitter on Thursday, left Oakland's 4-1 victory over the Blue Jays after sustaining a strained left hamstring while running out a groundout in the fifth inning at the Coliseum.
Smith, who put the A's on the scoreboard with an RBI single in the third inning to snap an 0-for-18 skid, was replaced in the seventh by Chris Carter.
The extent of his injury is not yet known, but the A's should have a better idea after he undergoes an MRI exam on Friday.
"I iced it, and it's still stiff, still sore, so I'll get an MRI tomorrow and see where to go from there," Smith said. "It's one of those things, you really can't speculate on until you wake up the next day and see where it is then."
It's the first injury of the year for Smith. If he were to be placed on the disabled list, the A's have a handful of outfielders at Triple-A whom they could look to for help, including Michael Taylor and Collin Cowgill.
