Before he strained his left calf during a May 17 game in St. Louis, Pastornicky, a right-handed hitter, was in position to get a majority of the starts at second base. Pena, a switch-hitter, has proven more successful when swinging from the left side of the plate.
But because the Braves believe Pena is most valuable as a bench player, they are not ready to institute a strict platoon. Because there is a greater abundance of right-handed starting pitchers, that arrangement would give Pena a majority of the playing time.
"It doesn't have to be a straight platoon," Gonzalez said. "If we feel like Tyler can handle a certain right-hander or Pena can handle a left-hander, we'll do it that way."
