2:08 pm: Glasnow’s MRI revealed a partial tear of his ulnar collateral ligament, as well as a flexor strain in his forearm, Adam Berry of MLB.com was among those to relay. It’s a brutal development, considering that UCL tears and flexor strains are often precursors to a Tommy John procedure. The current hope is that Glasnow can rehab the injury without surgery, relays Jeff Passan of ESPN, but it seems he’s in for a significant absence even in the best case scenario. The Rays haven’t released a formal timeline for his return, but he’s been placed on the 10-day injured list.
9:44 am: The Rays are sending Tyler Glasnow for an MRI on his elbow after the right-hander left last night’s start after four innings, Marc Topkin of the Tampa Bay Times was among those to report. The team announced Glasnow’s issue as elbow inflammation, with the pitcher telling reporters he felt “a little tug” and “tightness” in the area.
It’s an ominous-sounding diagnosis, but Glasnow himself didn’t sound overly concerned. “I think I got it relatively early. I just was like, I don’t want to go back out and chance it,” he said (via Topkin). “The (velocity) and everything was still there. But it just felt not right.” He did note, though, that the issue was more than mere discomfort. Glasnow missed most of the 2019 season with a forearm strain and suggested there’s a possibility his current issue is similar.
Certainly, the Rays will be holding their breath as they await the results of the MRI. Glasnow is amidst a stellar season, having worked to a 2.66 ERA/2.83 SIERA. He ranks fifth among qualified pitchers in strikeout rate (36.2%) and sixth in strikeout/walk rate differential (28.2 percentage points). He’s also been a true workhorse for a Rays pitching staff that otherwise tends to heavily leverage matchups, as Glasnow is tied for second in the American League with 88 innings pitched.
