Shane McClanahan

Shane McClanahan’s 2025 season is officially over, as Rays manager Kevin Cash told reporters that the southpaw underwent a surgery on his throwing arm today, intended to try and fix a long-lingering nerve problem.  The procedure officially closes the book on whatever chance there was that the southpaw could return to the majors before season’s end.

Troublingly, Cash indicated that there isn’t any guarantee that the surgery will solve the issue once and for all.  “[The doctor] is not sitting there saying ’he’s fixed.’  That’s not the case,” Cash told media, including Marc Topkin of the Tampa Bay Times.  “It’s, ’this is one step, and we’ll see how this goes.’  And hopefully we get good results.  And if we don’t, then let doctors decide what else is needed, if anything.”

The uncertain nature of nerve-related injuries has now led to months of frustration for McClanahan, and cost him another year of his promising career.  It was almost exactly two years ago that McClanahan underwent a Tommy John surgery that sidelined him for all of 2024, though it seemed like he emerged from that rehab in good shape, as he tossed seven scoreless innings in Spring Training and looked well on his way being part of the Opening Day rotation.

However, late in camp, the nerve problem in McClanahan’s left triceps emerged.  He began the year on the 15-day injured list, and was shifted to the 60-day IL near the end of April.  McClanahan was feeling well enough to begin a minor league rehab assignment in July and pitched in three games before his rehab was shut down due to biceps tendinitis.

During a radio interview on Friday, Rays president of baseball operations Erik Neander said McClanahan’s nerve problem was “still in play just enough” to keep the left-hander from resuming his throwing progression, with “no huge setbacks, but also no huge progress or breakthroughs.”  Neander also made note of the unique nature of the injury, saying “this is a new one to all of us really, and in many regards to the baseball community.  So we’re learning as we go.”

McClanahan’s best-case scenario is now a clean bill of health for Opening Day 2026.  While this gives McClanahan six months of recovery time until the start of Spring Training, it is clear that no timeline will be established until McClanahan is examined post-surgery.

Losing McClanahan in 2023 was a big blow to a Rays team that reached the postseason, but was swept out of the wild card series by the eventual World Series champion Rangers.  Tampa Bay went 80-82 in 2024 and, at 57-62 entering today’s action, is on pace for another losing record, as some early-season success was undone by a brutal slump in July.  One can only guess as to how the last three seasons might’ve differed for the Rays if they’d had a pitcher who was emerging as the ace of the rotation.

In a rare case of a player getting his first taste of MLB action in the playoffs, McClanahan’s first four games came during the 2020 postseason, as he posted an 8.31 ERA in 4 1/3 relief innings for a Rays team that reached the World Series.  McClanahan made his official debut in 2021, and hit the ground running in 2021 by finishing seventh in AL Cy Young Award voting.  He was then named an All-Star in both 2022 and 2023, and the 2022 campaign (McClanahan’s only full big league season) saw him finish sixth in AL Cy Young Award voting.  Over 404 2/3 regular-season innings, McClanahan has a 3.02 ERA, 46.8% grounder rate, 28% strikeout rate, and 7.1% walk rate.

Tampa signed McClanahan to a two-year, $7.2MM deal in January 2024 that allowed the two sides to avoid arbitration for the lefty’s first two years of eligibility.  As a Super Two player, McClanahan is arb-eligible both this winter and during the 2026-27 offseason, though his 2026 salary won’t be very high given his two years on the IL.  Injury uncertainty notwithstanding, there would seem to be very little chance the Rays would non-tender McClanahan given his modest price tag, and his upside if he is able to return healthy for 2026.

The Rays were dealt a frustrating blow this evening, as Marc Topkin of the Tampa Bay Times reports that southpaw Shane McClanahan has paused his throwing progression and is seeking additional medical opinions on the nerve issue in his triceps that’s kept him sidelined since Spring Training. The decision came after McClanahan was “not feeling 100%” during his first full-distance bullpen session. Manager Kevin Cash described the situation to reporters (including Topkin) as McClanahan being “kind of in shutdown mode.”

It’s tough news for Rays fans, as the talented left-hander was eyeing a return in late July as recently as last week. McClanahan hasn’t pitched in the majors since 2023 due to Tommy John surgery and the aforementioned nerve issue, but emerged as one of baseball’s most talented young starters during his three seasons in the league from 2021-23. He sports a career 3.02 ERA and 3.36 FIP across 404 2/3 innings of work. His resume also includes a fantastic 28.0% career strikeout rate and a 46.8% ground ball rate for his career.

Not being able to lean on McClanahan’s incredible talent at the top of the rotation last year is a major part of why the Rays stumbled to an 80-82 record and missed the postseason. Things are going better this year, as Tampa’s 36-31 record puts them in the second of the AL’s three Wild Card spots, just five games back of the Yankees for the AL East lead. The contributions of young bats like Jonathan Aranda and Junior Caminero have been key to the club’s success this year, and while Drew Rasmussen has done an admirable job as the team’s ace this year the Rays were surely counting on the return of McClanahan to help lift them down the stretch.

Outside of Rasmussen and a decent mid-rotation showing from Ryan Pepiot, the Rays haven’t gotten the best results from their rotation this year. Taj Bradley and Shane Baz have both been below-average pitchers this season, while Zack Littell has posted average results with shaky peripherals. A perennially changing but always talented cast of characters led by Pete Fairbanks in the bullpen has been excellent as always, but a strong bullpen can only do so much to prop up a rotation that lands in the bottom ten in baseball with a lackluster 4.35 FIP. It’s at least possible that McClanahan’s search for additional opinions will confirm that he’s ready to resume ramping up and this will be only a minor setback in his rehab, but for a pitcher who was already not guaranteed to return before August there’s real reason for concern that he could run out of time to get back before the end of the regular season in late September.

Should the Rays manage to keep the good times rolling and enter July as trade deadline buyers, the news regarding McClanahan seems likely to further amplify their need for rotation help. Tampa offloaded veteran rotation pieces Aaron Civale and Zach Eflin at last summer’s deadline, but adding a similar mid-rotation veteran to this pitching staff would go a long way to bolstering the rotation. Eflin himself could be on the market once again depending on how the Orioles decide to approach trade season in the midst of a nightmare year, and other pieces who could at least theoretically move this summer include players like Andrew Heaney, Tyler Mahle, Walker Buehler, and Zac Gallen although many of those players play for teams on the fence between buying and selling this summer.
