Cozart, who was in the lineup on Wednesday, was down for a few moments in the fifth inning when an 84-mph pitch banged off the front of the helmet near the left ear flap. He stayed in the game and hit a single in the seventh. Cozart said he underwent testing as protocol for any head trauma and passed easily.
In 2012, Cozart was also hit in the head by a Dodgers pitcher, Chad Billingsley, and came out of that game.
"I remember Dusty [Baker] came out there and said 'Your eyes just don't look right.' So he took me out of the game," Cozart said. "I did the concussion protocol and everything with the doctors and I passed. I played the next day."
