BOSTON, MA—The Boston Red Sox today placed right-handed pitcher Justin Slaten on the 15-Day Injured List (retroactive to April 5) with a right oblique strain. To fill his spot, Boston recalled left-handed pitcher Tyler Samaniego from Triple-A Worcester. Samaniego will wear number 78.
Slaten, 28, has made four relief appearances this year, throwing 3.1 innings and allowing one unearned run on two hits and two walks with five strikeouts. Originally selected by the Texas Rangers in the third round of the 2019 First-Year Player Draft, the Texas native owns a 3.30 ERA (34 ER/92.2 IP) with 88 strikeouts, a 1.05 WHIP, and .218 opponent batting average (76-for-349) in 84 career Major League games, all with the Red Sox (2024-26).
Samaniego, 27, has appeared in three games in relief with Worcester, allowing three runs (two earned) over 5.1 innings with five hits, two walks, and three strikeouts. The left-hander made 4 scoreless appearances for the Red Sox during Spring Training, recording six strikeouts in 5.1 innings while allowing one hit and two walks. Originally selected by the Pittsburgh Pirates in the 15th round of the 2021 First-Year Player Draft, the Alabama native was acquired by the Red Sox in a trade in December 2025 and owns a 3.80 ERA (69 ER/163.1 IP) in 130 career minor league games (two starts).
