Houston Astros manager Joe Espada announced on Sunday that right-handed pitcher Hayden Wesneski will undergo Tommy John surgery and miss the rest of the 2025 season.

The first-year Astro started at Milwaukee on May 6 and suffered the loss in a 4-3 setback. He allowed all four Brewer runs in four innings. Three days later, he was placed on the injured list with elbow inflammation.

Espada expects Wesneski to return during the 2026 season.

The Chicago Cubs sent Wesneski, a Houston native, along with Cam Smith to the Astros in exchange for All-Star outfielder Kyle Tucker last December. In 2022, the hurler was the Yankees’ seventh-ranked prospect, but New York dealt him to Chicago at the trade deadline for reliever Scott Effross.

Wesneski went back and forth between the starting rotation and the bullpen in three seasons with the Cubs, making 68 appearances overall (22 starts). All six of his 2025 appearances for the Astros were as a starter and he posted a 1-3 record with a 4.50 ERA, but a tidy 1.09 WHIP.

Wesneski owns a career ERA of 4.01 in 222 innings of work.

The Astros have suffered multiple injuries to their staff as Spencer Arrighetti, Luis Garcia, Cristian Javier and JP France are currently unavailable. To replace Wesneski, Houston called up prospect Colton Gordon, who started against Kansas City on Wednesday in his MLB debut.

Wesneski was selected by the Yankees in the sixth round of the 2019 draft.
