White Sox' Hanser Alberto left the game in the fifth inning after suffering an apparent shoulder injury while running to first base.
On the play, Alberto laid down a bunt and sprinted toward first base. As he crossed the bag, he began to give the sweeping "safe" sign, but suddenly doubled over in pain, grasping at his shoulder as trainers attended to him.
Shortly after his exit, White Sox said he is day-to-day with left shoulder soreness.
