Seranthony Dominguez

Dominguez had re-established himself as one of Philadelphia's most reliable relievers during the 2022 season, but he wasn't able to replicate that same success last year. The Dominican native struggled to a 3.78 ERA (4.67 xERA, 4.83 FIP) and 1.40 WHIP in 2023, while his strikeout rate plummeted by 8.1 percentage points to a below-average 21.4 percent. This was a significant drop for the 29-year-old, whose K-rate had been near or above 30 percent in every season prior. Dominguez's -0.73 WPA was dead last among Phillies relief pitchers one year after leading this unit in that statistic. He also missed over a month with an oblique strain. Dominguez's slider is effective, but he only throws it 27 percent of the time. He might be able to retain a high-leverage role if he throws the pitch more often, but he seems likely to work in middle relief for 2024. Read Past Outlooks
