Tyler Glasnow believes MLB’s crackdown on the use of foreign substances contributed to his arm injury.

Glasnow was removed from his start on Monday after four innings due to an arm injury. On Tuesday, the Tampa Bay Rays said Glasnow was out indefinitely with a torn UCL.

When speaking with the media Tuesday, Glasnow criticized MLB for cracking down on foreign substances during the season. He said he was using sunscreen and then had to scrap it midseason.

“I just threw 80 something innings and you just told me I can’t use anything. I have to change everything,” Glasnow said of MLB’s change.

The 27-year-old pitcher believes MLB’s crackdown, which led him to make adjustments, contributed to his injury.

“I truly believe 100 percent that’s why I got hurt. I’m frustrated MLB doesn’t understand. You can’t just tell us to use nothing. It’s crazy.”

Glasnow feels there is a difference between sunscreen, which he was using for a grip, and the extreme substances like Spider Tack, which players have gained advantages through using. He says no players have an issue with pitchers using sunscreen and rosin.

Players shouldn’t have any issue with the use of rosin, because it is legal. So Glasnow’s anecdote doesn’t really apply.

However, he does make a fair point about MLB put pitchers in a more difficult spot than necessary by cracking down midseason rather than the offseason. But if Glasnow’s colleagues weren’t abusing the system so much, MLB wouldn’t have to do what it’s now doing.
