Watch: Buster Posey drilled in head, exits game

San Francisco Giants star catcher Buster Posey was removed from Monday’s game when he was hit in the head with a fastball in his first plate appearance.

An 0-1 fastball clocked at 94 mph got away from Arizona Diamondbacks pitcher Taijuan Walker and nailed Posey’s helmet.

The good news is that Posey appeared to be okay after getting hit. He immediately popped up into a sitting position and quickly got back to his feet. So, the helmet did its job.

But Giants trainer┬áDave Groeschner wasted no time in removing Posey from the game. Based on Posey’s immediate reaction, it’s likely that his removal was more precautionary than anything. Still, this is something to monitor.
