Two players on the Guardians’ injured list underwent surgeries that will end their 2025 campaigns. (MLB.com’s Tim Stebbins was among those to report the news.) Outfielder Will Brennan had a Tommy John surgery to fix his damaged left UCL, and right-hander Andrew Walters had surgery to repair his right lat tendon. The TJ recovery timeframe for position players is usually around 6-8 months, so Brennan should be ready to go for Opening Day 2026, while Walters could miss some time at the start of next season given his projected timeline of 8-to-10 months. Walters is already on the 60-day injured list and Brennan will be shifted from the 10-day IL to the 60-day whenever Cleveland needs some room on its 40-man roster.
Brennan was a regular in Cleveland’s outfield in 2023-24, hitting .265/.303/.370 over 808 plate appearances (all but 121 of them against right-handed pitching). The platoon shield didn’t much help Brennan produce at the plate, and his very solid glovework in right field also took a big dip from 2023 to 2024. The Guardians’ acquisition of Nolan Jones just prior to Opening Day indicated that the team was moving in a new direction with its outfield platoon, and Brennan was indeed optioned to Triple-A to begin the season.
Called up on May 12, Brennan appeared in just six games with the Guards before he was placed on the 10-day injured list with what was initially deemed to be left forearm inflammation. Subsequent testing revealed the much more severe UCL damage, and it’ll now be a long while before Brennan is able to play in his next Major League game. He entered the season with two years and 15 days of official MLB service time, and so his earlier stint in the minors means that Brennan won’t gain a full third year even as he continues to amass service time on the Guardians’ big league IL.
As much as Brennan had become a backup plan for the Guardians, losing him for the remainder of 2025 will rob Cleveland of a depth option for its long-struggling outfield mix. Steven Kwan has again been the Guardians’ only productive outfielder, so adding some help on the grass would again appear to be a priority for the club heading towards the trade deadline.
Lane Thomas can hopefully provide some help from within, as Cleveland activated the outfielder from the 10-day IL today. Thomas has hit only .119/.169/.136 over 65 PA while missing most of the season due to two separate IL stints for a bone bruise in his right wrist and for plantar fasciitis in his right foot.
Walters was a second-round pick for the Guardians in the 2023 draft, and he made his MLB debut just over a year after his draft date when he made nine appearances for Cleveland last September. He started this season at Triple-A Columbus and spent just shy of three weeks on the minor league IL due to elbow inflammation, so he banked only 12 minor league innings this season to go along with his 1 1/3 innings in two appearances with the Guardians. Walters’ injury arose in the second of those appearances on May 30, when he left the mound in obvious discomfort after throwing a pitch to Mike Trout during the Guards’ 4-1 loss to the Angels.
The only slight silver lining here for Walters is that he’ll earn big league service time while on the IL, yet the lat surgery is obviously a rough setback for the 24-year-old righty. Somewhat of a rare case of a pitcher who has been almost exclusively a reliever both in college and in the pros, Walters has a 2.17 ERA and a 36.3% strikeout rate over 62 1/3 innings in the Guardians’ farm system. A 13% walk rate is a concern, but if Walters can manage his control, his live fastball and strikeout ability makes him a very intriguing candidate for high-leverage relief work once he gets healthy.

Lane Thomas is garbage. He will just make the team worse.
