"It's not real good, man. I've been hit a lot harder, but in other places they haven't hurt as much," Arroyo said. "It got me right in the belly of the calf, so it's got my foot locked up, it doesn't want to move. It feels like a charley horse cramp, but as the game went on, it got tighter and tighter. It may have helped my changeup today, I threw a lot of them and I couldn't really get after it. I probably had a shorter stride and it took some speed off the changeup. I made it through the game, I don't know how the next few days are going to be."
