Shane McClanahan won’t be back before the regular season ends, leaving Tampa Bay to plan its October pitching without one of its top arms for now.
McClanahan has been on the 15-day injured list since September 4 with left forearm tightness, and Marc Topkin of the Tampa Bay Times reported that he will not return during the regular season. He is still limited to playing catch. Manager Kevin Cash told Topkin and others that McClanahan had “ a good day ” playing catch on Friday, but Cash did not offer a timetable for the left-hander’s return.
The Rays have already punched their ticket to the playoffs and are likely to finish as the American League’s top seed. That would let them skip the Wild Card Series and open the postseason in the Division Series on October 3rd. The extra time helps McClanahan in theory, but with his status still uncertain, Tampa Bay may be preparing as if he won’t be available for that round.
Even without him, the Rays have a rotation picture that looks sturdy on paper. Drew Rasmussen has put together a 4.7 fWAR season and has established himself as the club’s ace and likely Game 1 starter. Nick Martinez and Griffin Jax have both turned in solid years as well.
McClanahan’s own season has been impressive considering the road back. The 29-year-old missed all of 2024-25 after Tommy John surgery and a nerve issue, then returned to post a 3.36 ERA across 118 innings this year.
His 21.8% strikeout rate is below his previous marks, but he has paired that with an 8.0% walk rate, a 31.6% chase rate, and a 44.2% ground ball rate, all above league average. Despite two trips to the IL, including one for left mid-back tightness, he has still produced 2.4 fWAR, good for third among Rays starters behind Rasmussen and Martinez.
If Tampa Bay is still waiting on McClanahan for the Division Series, the playoff rotation for a seven-game set would likely include Rasmussen, Martinez, Freddy Peralta, and one of Jax or Ian Seymour. Jax has handled the converted-reliever role capably, while Seymour has been effective without quite separating himself as a starter/bulk reliever.
If the Rays make it to the Championship Series, McClanahan could reenter the mix alongside Rasmussen, Martinez, and Peralta, with Jax and Seymour likely moving back to the bullpen. Even then, he would not be at full strength, since he would be returning after a month away without any minor league rehab appearances in between.

Rays Make A Tough Roster Call As Ben Williamson Returns
Ben Williamson is back on the active roster for the Rays after being reinstated from the injured list ahead of their game against the Red Sox, giving Tampa Bay another versatile infield option at a time when every roster spot matters. Williamson is expected to slide back into the same kind of role he held before the injury, working as a platoon second baseman and a backup shortstop.
To make that move, the Rays designated outfielder Jake Fraley for assignment, a tough call that underscores how crowded and fluid the roster can be this time of year. Williamsons return adds stability in the middle infield, but it also leaves Fraley in limbo as Tampa Bay sorts out its mix for the stretch ahead. [Read more 🡒]
Rays Deliver The Kind Of Win Red Sox Fans Hated
The Rays got exactly the sort of finish that can linger in a division race, squeezing out a tightly played game over the Red Sox with Richie Palacios delivering the walk-off hit. It was the kind of night built on pitching and pressure, with both clubs creating chances but neither able to separate until late, and the miscues on the bases only added to the tension.
Boston left disappointed, too, because the loss kept the Red Sox from clinching a postseason spot on the day. Tampa Bay now turns to the next game in the series with Griffin Jax lined up to start against Patrick Sandoval, and after a win like this, the Rays have a little extra juice heading into the matchup.

Rays Bullpen Picture Just Got More Complicated Before October
Casey Legumina gave the Rays a useful reminder of how quickly the bullpen conversation can change in September. The right-hander threw two scoreless innings with four strikeouts against the Red Sox, another solid showing at a time when Tampa Bay is trying to sort through injuries and settle on dependable late-inning options before the postseason.
Ian Seymour is part of that evaluation too, with the Rays weighing whether his role should shift as the regular season winds down. For a club still trying to map out its relief mix, performances like Leguminas only sharpen the choices, and they also make the October picture a little less clear than it was a few days ago.
