Jameson Taillon is doing well after he was hit in the back of the head with a line drive that left the bat at 105 mph on Tuesday night.

The Pittsburgh Pirates' athletic trainer said the point of impact was the logo on the back of Taillon's cap.

"I've been in baseball 18 years -- 10 in the majors -- and it's the first time I've seen a pitcher get hit in that particular place," Todd Tomczyk said.

Hernan Perez of the Milwaukee Brewers hit the second-inning line drive that struck Taillon in the back of the head. The rookie right-hander stayed in the game, allowing only one run over six innings.

"He's doing well today and we're monitoring him," Tomczyk said.

There were four barriers, Tomczyk said, that helped prevent a brain injury to Taillon: "The cap itself, the logo, his hair and his skull."
