PITTSBURGH -- Braves second baseman Dan Uggla was forced to exit Saturday night's 3-1 loss to the Pirates when his left calf tightened up after he grounded out in the fourth inning.
Uggla attempted to stretch his calf when he returned to the dugout. But instead of trying to play through the ailment in the chilly conditions, he informed Braves manager Fredi Gonzalez that he needed to leave the game.
"It's got to take something sticking out of his leg for him to come out," Gonzalez said. "It was smart on his part."
Uggla, who played through a similar ailment in 2011, is hoping to return to the Braves lineup for Monday's series opener against the Rockies.
"It was enough to where it could have gotten real bad if I had stayed in there," Uggla said. "I tried to loosen it up once I got back to the dugout. So I was like, 'It's cold, let's just go in and get it taken care of.'"
Ramiro Pena served as the Braves second baseman for the remainder of Saturday's game and will continue to handle that role until Uggla returns.
