The Phillies have signed right-handed reliever Seranthony Domínguez to a two-year contract extension with a club option for 2025, President of Baseball Operations David Dombrowski announced today.
The 28-year-old made a career-high 54 appearances in 2022, posting a 3.00 ERA with nine saves, a 1.14 WHIP and 61 strikeouts in 51.0 innings, while holding opponents to a .197 batting average. In the postseason, Domínguez pitched in every round, compiling a 2-0 record with a save, 1.69 ERA, 0.75 WHIP and 18 strikeouts to one walk in nine appearances. A native of the Dominican Republic, he is 11-10 with 25 saves, a 3.14 ERA and 165 strikeouts in 134.2 innings over 135 appearances since beginning his career with the Phillies in 2018.
Per Statcast data, Domínguez has averaged 97.8 mph on his fastball during his career, tied with teammate José Alvarado for the fastest among all 166 pitchers to throw at least 500 pitches for the team since pitch tracking began in 2008. He ranked in the 96th percentile among all pitchers in fastball velocity last season.
With Domínguez’s extension, the Phillies have now agreed to terms with all arbitration-eligible players for the 2023 season.
