Sophomore pitcher Austin Covers smiles while having his shoulder stretched by Herman Suncin, a graduate student in kinesiology from Morton Grove and the graduate assistant athletic trainer for the baseball team, Friday at the Saluki training facility at Garden Grove Event Center. Covers suffered an injury during his freshman season which required a surgery on his elbow. After a pitcher throws, Suncin completes manual resistance exercises to help strengthen the pitcher’s shoulder and keep it healthy throughout the season. The exercises specifically target the muscles of the rotator cuff and those used to decelerate the arm.
