BOSTON, MA—The Boston Red Sox today placed right-handed pitcher Sonny Gray on the 15-Day Injured List with a right hamstring strain. To fill his spot, Boston recalled left-handed pitcher Tyler Samaniego from Triple-A Worcester.
Gray, 36, started yesterday against the Detroit Tigers and pitched 2.2 innings. The right-hander has gone 2-1 with a 4.30 ERA (11 ER/23.0 IP) in five starts this season. Selected by the Athletics in the first round (No. 18 overall) of the 2011 First-Year Player Draft, the Tennessee native owns a 3.59 ERA (774 ER/1941.0 IP) with 1,938 strikeouts across 344 career Major League games (335 starts) with the Athletics (2013-17), New York Yankees (2017-18), Cincinnati Reds (2019-21), Minnesota Twins (2022-23), St. Louis Cardinals (2024-25) and Red Sox (2026).
Samaniego, 27, made his Major League debut on April 8 against the Milwaukee Brewers, and has thrown 3.2 hitless, scoreless innings with three walks and four strikeouts over three games with Boston. The left-hander also has a 5.68 ERA (4 ER/6.1 IP) in four relief appearances with Triple-A Worcester this year. 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 3.89 ERA (71 ER/164.1 IP) in 131 career minor league games (two starts).
