While there was some concern about the severity because Martinez missed the entire 2012 season due to microfracture surgery on his left knee, he brushed it off.
"Just a little cramp. but that was it," Martinez said. "Anyway, I was going to get a pinch-runner, so not a big deal."
Martinez has been one of the top hitters in the Tigers lineup, going 2-for-4 in Game 3 on Tuesday, and improving to 13-for-31 (.419) with five extra-base hits and three RBIs in the postseason.
