BOSTON, MA—The Boston Red Sox today signed left-handed pitcher Ranger Suárez to a five-year contract through the 2030 season with a mutual option for 2031. Boston’s 40-man roster is now at 40.
Suárez, 30, made 26 starts for the Philadelphia Phillies in 2025, going 12-8 with a 3.20 ERA (56 ER/157.1 IP) while setting career highs in strikeouts (151), innings pitched, and quality starts (17). The left-hander’s career-best 4.0 FanGraphs WAR tied the sixth-best mark among National League pitchers, while he ranked seventh among that group in ERA (minimum 150.0 IP). He also ranked in MLB’s 98th percentile during 2025 in hard-hit percentage (31.1%) and 95th percentile in average exit velocity (86.5 miles per hour). Signed by Philadelphia as an international free agent in April 2012, the Venezuela native has gone 53-37 with a 3.38 ERA (286 ER/762.0 IP) and 705 strikeouts in 187 career Major League games (119 starts), all with the Phillies (2018-25). He was named a National League All-Star in 2024 and won the 2022 Fielding Bible Award among pitchers.
In 11 career Postseason games (eight starts), Suárez has gone 4-1 with a 1.48 ERA (7 ER/42.2 IP), .203 opponent batting average (32-for-158), and 44 strikeouts. He has allowed 1 or 0 earned runs in 10 of those 11 outings, including 5.0 scoreless innings with just three hits allowed in Game 3 of the 2022 World Series against the Houston Astros. During the 2025 Postseason, he earned the win in Game 3 of the National League Division Series by allowing one run over 5.0 innings of relief in the Phillies’ 8-2 victory over the Los Angeles Dodgers.
