"I want to play," Martinez said. "I'm going to do everything I can."
Martinez was in immediate pain after fouling off the pitch from Kevin Gausman, stretching and limping for a few minutes as head athletic trainer Kevin Rand checked on him. Martinez struck out and went immediately to the clubhouse as Tyler Collins began to stretch in the dugout.
Martinez emerged to take his spot in the field for the bottom of the second, but was still limping. He went back to the clubhouse for the third inning and stayed there. Collins took over in right field for the bottom of the inning.
"They wrapped it up right away and I thought I was going to be fine," Martinez said. "I got out there and, when you hit a foul ball off your calf or your foot it hurts and then you wait for it to subside. That's what I was doing, but when I put weight on it, my whole leg just felt weak. It wasn't pain. I think it was my body protecting itself because of the pain. It just felt unstable putting weight on it.
"When I was going back for that fly ball, just putting weight on it, I started limping right away and I said, 'I'm no good out here.'"

He leads the team with 28 home runs and 68 RBIs, and his offense Wins Above Replacement of 3.3 ranked 10th among American League players entering Saturday.
