Officially listed as day-to-day, Upton's ring and middle fingers on his left hand locked up during his first at-bat, resulting in a strikeout at the hands of Tom Koehler.
"He kept saying he couldn't open his hand," Braves manager Fredi Gonzalez said on braves.com. "The muscle of the forearm, he just kept putting the two middle fingers and clamping them and he couldn't open them, and it did that a couple of times in the dugout when he came in when [assistant athletic trainer Jim Lovell] was checking him, so we said forget it."
Upton blamed the amount of work he put into pre-game hitting drills for the spasms, also noting that they had occurred before, but the fingers locking was something new.
"It was like I could get it to calm down, but as soon as I went to grip the bat again, it's almost like my hand would lock up around the handle of the bat," Upton said. "It was different. I tried to grind it out, and once I got into the dugout, I kind of knew what it was, but at that point, you have make a decision whether to stay in or take me out of the game. Obviously, it's not something you want to risk, but having it happen to me in the past, I knew I'd be OK."
Upton expects to be able to play Wednesday's game.Tags: Atlanta, Atlanta Braves, B.J. Upton, Baseball, Fredi Gonzalez, MLB
