While pitching to Erick Aybar, he took a line driver to the head, and then hit his head hard on the ground as well.
Good news was that McCarthy not only got up after being hit, but never lost consciousness.
He was taken out of the game and taken by ambulance to the hospital.
His hospital visit was merely precautionary, and it seems he didn't even suffer a concussion.
McCarthy is now hoping he didn't use up all his luck surviving the hit.
