DETROIT — In the fourth inning, Victor Martinez hit a leadoff single for the Tigers' fifth hit of the game.
Torii Hunter then stepped to the plate and laced a single to put two aboard. But once at first base, Hunter reached for his right hamstring.
Tigers manager Brad Ausmus and head athletic trainer Kevin Rand immediately came out upon being motioned by Hunter, but instead of being met at the bag, Hunter was already halfway to the dugout.
A visibly frustrated Hunter immediately left the game upon talking to Ausmus and Rand, and was replaced by J.D. Martinez at first base, who pinch ran for Hunter in the fourth and remained in the game.
Austin Jackson followed with an RBI single to center field but J.D. Martinez overran the bag at second base, and in his attempt to advance, was putout at second.
Hunter is officially listed as having left the game for a right hamstring cramp, and is listed as day-to-day.
