Astros P Brad Peacock has PRP injection in side

Astros pitcher Brad Peacock underwent a platelet-rich plasma injection to his side, according to the Houston Chronicle. 

It's the first time Peacock has ever had the shot. 

"When I rotate it hurts a little bit," Peacock said. 

Peacock was placed on the 15-day disabled list on April 17 with what was diagnosed as a left intercostal strain. He's only made one start this season.
