Tyler Glasnow’s season might already be over.
An MRI of the Rays ace’s arm revealed a partial UCL tear and a flexor strain, according to multiple reports.
Further medical evaluation will be needed to establish a timeline for Glasnow’s return. In the interim, he was placed on the 10-day injured list.
According to ESPN’s Jeff Passan, the Rays and Glasnow are hoping to rehab the injury and avoid Tommy John’s surgery.
If it comes down to Tommy John’s surgery, Glasnow would be out for the rest of 2021. Glasnow is 5-2 this season with a 2.66 ERA and 123 strikeouts — second-most in MLB — in 88 innings.
The 27-year-old righty left Monday’s win over the White Sox after the fourth inning after experiencing pain in his elbow. In the course of the game, he struck out six players and walked one, throwing 40 of his 53 pitches for strikes. At the start of the fifth, he was replaced by Ryan Thompson.
“The last couple of pitches I felt just a little tug,” Glasnow told reporters following the game. “I didn’t want to go out and chance it. The [velocity] was still there, it just felt not right.”
The injury is a big blow for the Rays (43-24), who entered Tuesday with the best record in the majors. They held a three-game lead on the Red Sox in the AL East and were up nine games on the fourth-place Yankees.
