Rays' Shane McClanahan to undergo Tommy John surgery

Rays ace Shane McClanahan will require Tommy John surgery next week, reports Marc Topkin of the Tampa Bay Times. He’s expected to miss the entire 2024 campaign.

It’s a devastating if not entirely unexpected development. The two-time All-Star left his start on Aug. 2 after experiencing forearm discomfort. Tampa Bay has been exploring their options for the past couple weeks, though the club had already confirmed he was expected to miss the remainder of 2023 and that surgery was a consideration. He’s already on the 60-day injured list.

Surprising or not, it’s hard to overstate the significance of losing a pitcher of McClanahan’s caliber. The former first-round draftee debuted with 25 starts of 3.43 ERA ball two seasons ago. 

By his second major league season, he’d broken through as one of the game’s best pitchers. McClanahan was a legitimate Cy Young contender into August last year before a shoulder impingement cost him a couple weeks.

The absence dropped the South Florida product to sixth in Cy Young balloting, but he still finished his sophomore campaign with a 2.54 ERA through 166 1/3 frames. While his ERA took a bit of a step back this season, a 3.29 mark over 21 starts still ranks 19th among big league starters (minimum 100 innings). He’s 23rd among that same group with a 25.8% strikeout rate. McClanahan earned his second consecutive All-Star nod last month.

Tampa Bay has dealt with a brutal stretch of pitching injuries over the past few months. Top prospect Shane Baz has missed the entire year after undergoing a Tommy John procedure last September. 

McClanahan becomes the third member of the Rays’ season-opening starting staff to require surgery this year. Jeffrey Springs required a Tommy John procedure in April; Drew Rasmussen underwent flexor tendon surgery last month.

Even after the absences to Baz, Springs and Rasmussen, the Rays had an effective top of the rotation. McClanahan, Tyler Glasnow and Zach Eflin made for an excellent trio. 

With McClanahan now out of the picture, Glasnow assumes the role of staff ace. Eflin — who has dealt with knee issues throughout his career but has a 3.67 ERA through 23 starts in his first season with Tampa Bay — is the No. 2 option.

The early-season injuries led the Rays to acquire Aaron Civale from the Guardians at the deadline. That acquisition takes on increased importance with McClanahan out. Still, there’s little recourse beyond internal options for Tampa Bay in patching together the final two rotation spots. 

Taj Bradley has been up-and-down as a rookie and is on optional assignment to Triple-A. The Rays have pushed Zack Littell into the rotation and recently activated Josh Fleming from the injured list.

Tampa Bay enters play Tuesday three games back of the Orioles in the AL East. They’re still in strong playoff position, 7.5 games clear of the Mariners (the top non-playoff team in the AL). 

Their chances of running down Baltimore to secure a first-round bye and/or making a deep run once they get into October are obviously dealt a hit by the loss of one of the game’s best starters.

This is the second Tommy John procedure of McClanahan’s career. He missed his freshman year at USF after undergoing surgery in 2016. The Rays figure to be especially cautious with his recovery as a result, although there’s a good chance he would have missed all of ’24 even if this were his first TJS.

McClanahan has just under three years of major league service. He’ll be eligible for arbitration as a Super Two player next offseason. The Rays will need to carry him on their 40-man roster during the offseason but will immediately place him back on the 60-day IL next spring. 

He’ll collect service time while rehabbing and remains on track to first reach free agency after the 2027 campaign.
