Rays ace out through at least the All-Star break

The Rays have been dealt another huge blow to their rotation. As first reported by Marc Topkin of the Tampa Bay Times, Tampa Bay placed starter Drew Rasmussen on the 60-day injured list after the righty was diagnosed with a flexor strain in his forearm. He’ll be out until at least the All-Star break.

It’s an out-of-the-blue development. Rasmussen pitched Thursday and didn’t show any signs of being hampered. He twirled seven shutout innings in a win over the Yankees, striking out seven while allowing just two baserunners. The velocity on each of his fastball, slider and curveball was right in line with his previous work this season.

Surprising as it is, Rasmussen apparently came down with a severe forearm issue from that appearance. Topkin notes that he’s hopeful of avoiding surgery, but he’s obviously in line for a notable absence in any event. The Rays wasted no time in putting him on the 60-day IL, indicating they didn’t feel there was any chance of him being back on an MLB mound before July.

It’s horrible news for the 27-year-old hurler. Rasmussen has a checkered injury history. He underwent Tommy John surgery midway through his sophomore year at Oregon State in 2016. The Rays drafted him in the first round the following year, but issues with his post-draft physical led the team to decline to sign him. Rasmussen subsequently underwent a second Tommy John surgery and didn’t pitch as a senior, causing him to fall to the sixth round of the 2018 draft.

Selected by Milwaukee, Rasmussen debuted in the majors as a reliever with the Brew Crew in 2020. The Rays acquired him alongside J.P. Feyereisen for Willy Adames and Trevor Richards in May 2021. Tampa Bay began to stretch him back out to starting at the end of that season and has seen him blossom into an excellent starting pitcher over the past couple of years.

Rasmussen started 28 games and tallied 146 innings last season. He worked to a 2.84 ERA with a decent 21.4% strikeout rate and an excellent 5.3% walk percentage. He’d been off to an even better start this year. Thursday night’s performance brought him to 44 2/3 frames of 2.62 ERA ball over eight outings. He punched out 26.6% of batters faced and upped his ground-ball rate to a strong 52.6% clip.

His stellar early-season work was among the reasons the Rays have sprinted to a 30-9 start. They’re remarkably five games up in a division in which every team is at least three games above .500. It has been an incredible first few weeks for Tampa Bay, but they’re navigating a mounting number of rotation injuries. They were always going to be without Shane Baz for the bulk of the season after last year’s Tommy John procedure. Tyler Glasnow has been out all year after a spring training oblique strain. He’s on a minor league rehab assignment and should be back within the next couple of weeks, but left-hander Jeffrey Springs is out for the season after undergoing a Tommy John procedure of his own.

Rasmussen’s injury leaves Shane McClanahan as the last starter who has been a constant all year. Offseason signee Zach Eflin missed some time with lower-back tightness but returned a couple of weeks ago. He’s been excellent through six starts. Tampa Bay has gotten their first look at top pitching prospect Taj Bradley, who seems likely to return from Triple-A Durham to eventually take Rasmussen’s rotation spot. Josh Fleming and Calvin Faucher have worked in a swing capacity and could take some starts, as could one-time starter Yonny Chirinos. Cooper Criswell and Luis Patiño are on the 40-man roster and working out of the rotation in Durham.

Depending on Rasmussen’s long-term prognosis, it’s possible the Rays eventually look outside the organization for rotation depth. They’re going to be left to rely mostly on internal options until the trade deadline draws nearer, though.

Rasmussen will be paid around the MLB minimum rate and collect big league service while on the injured list. He’s slated to be eligible for arbitration for the first time at the end of this season and is controllable through 2026. He and the organization will obviously hope he’ll be able to avoid another serious arm procedure and return to the mound without too extended of an absence.
