2026 Projections
2026 Fantasy Outlook
Dominguez's 13.8 percent walk rate in 2025 was among the worst in the league for relief pitchers, but the veteran finished in the 90th percentile or better across several Statcast metrics, including fastball velocity (97.7 mph), whiff percentage (33.3), strikeout percentage (30.3) and expected batting average (.200). The 31-year-old also established new career-high marks for games played (67), innings pitched (62.2), strikeouts (79) and holds (20) between Orioles and Blue Jays. He has a vast, five-pitch arsenal -- including an effective sweeper and splitter that produced some of the highest whiff rates for those pitch types -- with 40 saves and 82 holds on his career ledger. Dominguez joined up with the White Sox on a two-year, $20 million contract in January to reportedly serve as the team's closer. His saves volume will be capped on a bad team, but landing in Chicago should also afford him decent job security. That may not last for all of 2026 if he pitches well, however, since being a reliever on the White Sox automatically makes him an early candidate to be traded. Read Past Outlooks
Signed a two-year, $20 million contract with the White Sox in January of 2026.
Signs with ChiSox to become closer
The White Sox signed Dominguez to a two-year, $20 million contract Friday, Jeff Passan of ESPN.com reports.
Analysis
There's also a mutual option for 2028, per Joel Sherman of the New York Post. Passan says the White Sox plan to use Dominguez as their closer. Dominguez has some closer experience, having notched 40 saves in his career, including 11 in 2024 between the Phillies and Orioles. The 31-year-old is coming off a 2025 campaign that saw him collect a 3.16 ERA and 79:36 K:BB over 62.2 regular-season frames between the Orioles and Blue Jays. Dominguez boasts a career 27.9 percent strikeout rate, but free passes (career 10.5 percent walk rate) have been a problem. With Dominguez taking over the ninth inning, previous incumbent closer options Jordan Leasure and Grant Taylor will work earlier in games.

2019
2018
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.

Latest Fantasy Rumors
Target for Arizona?
The Diamondbacks could pursue Dominguez as they attempt to improve their bullpen, reports Jack Sommers of SI.com.
Analysis
The right-hander is one of the top relievers left on the market, and Arizona could use some help in the bullpen with A.J. Puk and Justin Martinez recovering from elbow surgery.
