With one out in the fifth inning, Scutaro took off from second base to steal third. As Scutaro slid into the third-base bag, Chicago catcher Corky Miller's throw hit Scutaro in the chest. Batter Aaron Hill drew a walk on the play.
Scutaro was safe but asked the umpire for time as he rolled on the ground, clutching his chest in pain. Blue Jays head trainer George Poulis and manager Cito Gaston came onto the field to check on him.
"You could hear the ball from the dugout when it hit him," Gaston said. "Hopefully he's going to be fine."
Scutaro stayed in the game and scored on a groundout by Toronto right fielder Alex Rios, but was replaced at shortstop by John McDonald at the top of the seventh inning.
"He was just sore -- hurting a little bit," Gaston said. "We wanted to make sure he was OK."
Scutaro has started every game at shortstop for Toronto this season and is hitting .286 with five home runs and 20 RBIs. The veteran utility man entered the game leading the Majors with 33 walks.
