BOSTON, MA—The Boston Red Sox today signed right-handed pitcher Walker Buehler to a one-year contract for the 2025 season.

Boston’s 40-man roster is now at 40.

Buehler, 30, is a two-time All-Star (2019, ’21) and two-time World Series champion (2020, ’24). A 2021 All-MLB First Team selection, the right-hander finished in the top 10 in Cy Young Award voting in 2019 (ninth) and 2021 (fourth). In seven seasons with the Los Angeles Dodgers (2017-22, ’24), he went 47-22 (.681) with a 3.27 ERA (259 ER/713.2 IP), 1.09 WHIP, .221 opponent batting average, and 754 strikeouts over 131 appearances (122 starts).

After missing the entire 2023 season recovering from Tommy John surgery, Buehler made 16 regular season starts in 2024 and went 1-6 with a 5.38 ERA (45 ER/75.1 IP). He helped the Dodgers win a World Series title by posting a 3.60 ERA (6 ER/15.0 IP) in four Postseason outings (three starts), allowing zero runs in his final 13.0 innings pitched and earning a save with a perfect ninth inning in the decisive Game 5 against the New York Yankees. In 19 career Postseason games (18 starts), Buehler is 4-4 with a 3.04 ERA (32 ER/94.2 IP) and .210 opponent batting average. He has allowed only one run in 19.0 World Series innings (0.47 ERA) spanning four games (three starts), going 2-0 with one save, 24 strikeouts, and three walks in the Fall Classic.

Selected by the Dodgers in the first round (No. 24 overall) of the 2015 First-Year Player Draft, Buehler graduated from Henry Clay High School in Kentucky before pitching at Vanderbilt University from 2013-15.
