Reds right-hander Carson Spiers will undergo a Tommy John surgery that will end his 2025 season and cost him all or virtually all of the 2026 season, MLB.com’s Mark Sheldon reports. Spiers hasn’t pitched since April due to a shoulder impingement, and a minor league rehab assignment that began in early July was cut short when Spiers experienced some biceps soreness. However, an MRI revealed the much worse news of UCL damage, and the righty now faces a lengthy stint on the sidelines.
Spiers has at least been amassing Major League service time while on the Reds’ IL, and he’ll continue to do so during his time on the 60-day injured list in 2026. Given the usual 13-15 month recovery timeline for Tommy John patients, the timing of the surgery makes it unlikely that he’ll be back on a big league mound until the 2027 season, unless Spiers can perhaps get back in time for a peace-of-mind outing or two at the very end of the 2026 campaign.
Now in his third MLB season, Spiers was an undrafted free agent from the 2020 class of players who were somewhat left in limbo when the pandemic reduced the 2020 draft to just five rounds. He made it to the Show for a few appearances for Cincinnati in September 2023, and then played a larger role for the Reds last year, tossing 90 2/3 innings while starting 10 of 22 games. His abbreviated 2025 campaign consisted of two starts in three appearance, and 13 1/3 innings.
When not starting, Spiers has also operated as a long reliever, bulk pitcher, and a piggyback type of pitcher, so his ability to eat innings was helpful even if the results were shaky. Spiers has a 5.69 ERA over his 117 career frames in the majors, as well as a 19.3% strikeout rate and 7.7% walk rate. His career Triple-A numbers are a little better, and inflated by the 5.94 ERA he posted in 16 2/3 frames with Triple-A Louisville this year during his rehab assignment, when Spiers was naturally focused on getting comfortable and healthy rather than pure performance.
