The Boston Red Sox placed right-hander Tanner Houck on the 15-day injured list on Wednesday because of a right flexor pronator strain.

The move is retroactive to Tuesday. In a corresponding move, the Red Sox recalled right-hander Cooper Criswell from Triple-A Worcester.

Houck yielded 11 runs, nine hits (including two home runs) and three walks in 2 1/3 innings Monday night in a 14-2 loss at Detroit.

“This is definitely probably the most lost I’ve ever been,” Houck, 28, said after the game. “And just not getting the job done, which weighs on me heavily.”

Asked about his health, Houck said, “Physically, I feel good,” and added, “I just need to be better.”

Houck is 0-3 with an 8.04 ERA, 17 walks, 32 strikeouts, an America League-high 57 hits allowed and a major league-worst 39 earned runs in 43 2/3 innings over nine starts this season.

An All-Star in 2024, Houck owns a career 24-32 record with nine saves, a 3.97 ERA, 158 walks and 449 strikeouts in 474 1/3 innings over 113 regular-season games (80 starts) since 2020.

The Red Sox selected Houck 24th overall in the 2017 MLB Draft out of the University of Missouri.

Criswell, 28, is 0-0 with one save, a 10.38 ERA, one walk and no strikeouts in 4 1/3 innings over three relief appearances this season. For his career, he is 7-7 with one save, a 4.78 ERA, 44 walks and 104 strikeouts in 141 1/3 innings over 41 games (20 starts) for the Los Angeles Angels (2021), Tampa Bay Rays (2022-23) and Red Sox (2024-present).
