2025 Fantasy Outlook
Dominguez pitched a career-high 58.2 innings across 63 appearances between Philadelphia and Baltimore last season. His ratios and 12 home runs allowed (1.8 HR/9) typically wouldn't suggest a late-inning role, but Dominguez closed out 2024 as the Orioles' closer, racking up 10 of his 11 saves overall across the final two months. The veteran threw far more sliders (40 percent usage) in 2024, which bumped his K-rate to an above-average 26.7 percent. Dominguez is likely to continue pitching high-leverage innings for Baltimore after the O's exercised his $8 million club option for 2025. Read Past Outlooks

Notches save in return
Dominguez (back) picked up his second save of the season in Sunday's 2-1 win over Atlanta, striking out two while allowing one earned run on two hits over one inning.
Analysis
Dominguez wasn't available for either of the Orioles' previous two games due to a sore back, but interim manager Tony Mansolino was comfortable turning to the right-hander to protect a two-run lead in the ninth inning Sunday with normal closer Felix Bautista being rested following appearances on both of the past two days. The save didn't come easily for Dominguez, who gave up a one-out solo home run to Sean Murphy before Ozzie Albies singled to put the tying run on base. However, Dominguez settled in thereafter, striking out Drake Baldwin and then inducing a weak grounder from Michael Harris to close out the contest. The 30-year-old Dominguez has posted a 3.31 ERA, 1.25 WHIP and 47:20 K:BB across 35.1 innings this season while working primarily in a setup role.

Past Fantasy Outlooks
2024
2023
2021
2020
2019
2018
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.

Latest Fantasy Rumors

Orioles could shop him around
Dominguez is one of several relief pitchers the Orioles might make available for trade before the deadline, Jim Bowden of The Athletic speculates.
Analysis
The Orioles have had a disappointing season in 2025, and it wouldn't be surprising to see some of their arms being involved in trade talks over the coming weeks. While Dominguez's numbers aren't impressive, his experience as a veteran could be enticing to some contenders. Dominguez owns a 4.44 ERA across 24.1 innings this season.
