Pastornicky and Heyward collided as both attempted to catch a pop fly. Each player called for the ball. Pastornicky said he couldn't hear Heyward because of the crowd and the fact he also was calling for the ball.
"Jason just kind of clipped him, but (Pastornicky's) foot was planted when he got spun a little bit," Gonzalez said.
Pastornicky said both players called for the ball.
"We both got to the ball at the same time," Pastornicky said. "Just one of those freak plays."
Gonzalez said Pastornicky, who was making only his fourth start at second base, had not spent enough time at the position to become familiar with Heyward's range in right field, including his ability to run in for shallow fly balls.
