Shane McClanahan Undergoes Season-Ending Arm Procedure To Address Nerve Problem

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.
