Red Sox starting pitcher Tanner Houck will undergo Tommy John surgery. Manager Alex Cora broke the bad news to reporters today, including Christopher Smith of MassLive. The right-hander has been on the injured list since mid-May with a flexor pronator strain, and he was recently transferred to the 60-day IL after the team pulled him off a rehab assignment. Even in a best-case scenario, he will not return to the Red Sox until late in the 2026 season, and possibly not until 2027.
Boston’s first pick (24th overall) in 2017, Houck pitched well for the Sox from 2020-22 (3.02 ERA, 3.50 SIERA in 146 IP). Yet, rotation battles and a bad back kept him from earning a full-time job in the starting five until 2023, and a terrifying liner to the face that summer kept him from pitching his first full season until 2024. It proved to be a year worth waiting for, however, as Houck made 30 starts with a 3.12 ERA and earned an All-Star selection that summer.
Houck came into the 2025 season as Boston’s number two starter. Yet, he struggled badly over the first six weeks of the year, pitching to an 8.04 ERA with a 15.8% strikeout rate and 8.4% walk rate through nine starts. Those numbers were heavily affected by two different outings in which he gave 11 earned runs and failed to escape the third inning. Indeed, as MLBTR noted back in May, “If those two games were scratched from the register, his ERA would drop to 3.92, and his strikeout and walk rates would look much closer to what they were last season.” That said, to overlook two starts of such poor quality would be a mistake. Something was clearly wrong.
