If you’re looking for the best $20 million the White Sox spent this offseason, just watch the ninth inning.
Seranthony Domínguez has officially shaken off his early-season struggles and locked down the closer’s role with authority. By picking up his 6th save of the season on Friday night against the Nationals, the hard-throwing right-hander has become the steady anchor this young White Sox bullpen desperately needed.

The road wasn’t entirely smooth. Domínguez hit a rough patch earlier this month against the Rays, surrendering a late lead and drawing plenty of second-guessing from fans. But instead of folding, the veteran leaned into his elite stuff and has been one of the most dominant relievers in the American League since.
The “Seranthony Experience” is built on pure power: a 99-mph four-seam fastball that seems to explode on hitters and a high-spin sweeper slider averaging over 2,600 rpm. On Friday, he used that devastating slider to strike out dangerous hitter James Wood to seal the victory — a classic display of late-inning dominance that silenced any remaining doubts.
“When you have a guy like Seranthony at the back end, the game feels like it’s only eight innings long,” starter Anthony Kay said. “He walks out there with that presence, and you just know the job is getting done. He took some lumps early, but that’s closer life. He’s the anchor of this staff right now.”
Domínguez’s return to form has stabilized the entire bullpen. By shutting the door in the ninth, he’s allowed younger arms like Tyler Davis and Osvaldo Bido to thrive in lower-leverage spots. His veteran leadership has also been invaluable for top prospect Noah Schultz, who has leaned on Domínguez for advice on pitch sequencing and mental approach in big moments.

As the White Sox push into a pivotal stretch of the schedule, the lockdown presence in the ninth inning is their biggest asset. Seranthony Domínguez isn’t just closing games — he’s giving this talented young roster the confidence to play free and aggressive, knowing the game will be finished when it reaches him.
In the pressure-cooker environment of Chicago baseball, Domínguez is the steady veteran making sure the “W” flag flies at the end of the night. The ninth inning belongs to him again — and the South Side is breathing easier because of it.
