"He kind of got hit on the back of the head," Redmond said. "He seems like everything is fine, as of right now, which is a big relief. It looks like he's going to be fine."
Leading off the eighth inning, Polanco was plunked by Santiago Casilla's 94 mph fastball. Polanco fell to the ground and was immediately tended to by team athletic trainer Sean Cunningham. Collecting himself, Polanco sat up as he was examined. A few minutes later, he walked off the field and was replaced by Ed Lucas.
"I hope Polanco was OK," Giants manager Bruce Bochy said. "That was a scary moment right there."
The Giants prevailed by four runs on a night both teams combined for a Marlins Park record for runs (24) and hits (35). Polanco went 1-for-4 with an RBI on the night. He is batting .253 on the sason with one home run and 21 RBIs.
The Marlins have been using Polanco and Lucas at third base.
"They evaluated him when they took him into the training room," Redmond said. "He didn't show any signs of a concussion. He should be fine. But obviously, we're going to monitor him day to day."
