It’s probably safe to say that Tyler Glasnow is not a fan of Major League Baseball’s decision to crack down on pitchers’ use of sticky substances. 

The Tampa Bay Rays right-hander said Tuesday that he stopped using sunscreen, the only foreign substance he claims he has ever used, two starts ago and felt sore the next day because he had to adjust his grips.

He didn’t use any sticky substance again against the Chicago White Sox on Monday and felt something “pop” in his arm. The 27-year-old suffered a partially torn UCL and is hoping he can avoid Tommy John surgery. 

Glasnow added that he understands what the league is trying to do in eliminating foreign substances. However, he said he wishes they did it during the offseason to allow pitchers to adjust better.
