Seranthony Domínguez has pitched in big moments.
That was one of the traits that stood out to the Chicago White Sox.
“That level of experience is going to be really valuable,” general manager Chris Getz said Thursday after the Sox finalized a two-year, $20 million deal with the right-hander reliever.
The contract includes a $1 million signing bonus and mutual option for the 2028 season. Under terms of the agreement, Domínguez will receive $7 million in 2026 and $10 million in 2027, with a $12 million mutual option for 2028 or a $2 million buyout.
Reports of the deal first surfaced Friday.
Getz and manager Will Venable discussed the addition Thursday during an art makerspace community event at the Boys & Girls Clubs of Chicago, Bartlett J. McCartin Club in Bridgeport, which served as a lead-in to this weekend’s SoxFest Live festivities.
“He’s got big stuff and he’s got an ability to get both-sided hitters out,” Getz said of Domínguez . “We felt like he was the top remaining reliever on the market, and we’re excited we were able to convert on it.”
Domínguez, 31, had a 3.16 ERA, two saves and 20 holds in 67 combined relief outings for the Baltimore Orioles and Toronto Blue Jays in 2025. He had 79 strikeouts in 63 2/3 innings pitched.
Domínguez set career highs in appearances, innings, holds and strikeouts last season. He limited right-handed batters to a .132/.269/.182 slash line (16-for-121).
He joins a bullpen that includes right-handers Grant Taylor and Jordan Leasure.
“We’re talking about a bullpen now that is going to allow us to get to the finish line to stack up more wins,” Getz said.
Domínguez is 23-23 with a 3.50 ERA and 40 saves in 322 career relief appearances during seven major-league seasons with the Philadelphia Phillies (2018-19, 2021-24), Orioles (2024-25) and Blue Jays (2025). He has 360 strikeouts in 306 innings.
Domínguez has a 1.86 ERA with 37 strikeouts in 29 innings during 29 career postseason appearances, including a 1.93 ERA in five games for the Blue Jays in last year’s World Series against the Los Angeles Dodgers.
“He’s going to be finishing a lot of games for us,” Venable said. “We definitely view him as somebody that is going to lock us down at the back end.”
To make room for Domínguez on the 40-man roster, the Sox designated infielder Bryan Ramos for assignment.
Ramos, 23, went 2-for-12 (.167) with two doubles, two RBIs and one run in four games with the Sox in 2025. In 36 career games with the Sox from 2024-25, Ramos had a .198 average (22-for-111) with six doubles, three home runs and 13 RBIs.
The moves were part of a busy day for the Sox, who earlier Thursday announced that outfielder Braden Montgomery and pitchers Noah Schultz and Hagen Smith were among the 22 nonroster invitees to spring training camp. It’s the second straight year the three highly touted prospects received invitations to camp.
Montgomery, the No. 36-ranked prospect in baseball according to MLB.com, had a combined .270/.360/.444 slash line with 12 home runs and 68 RBIs in 121 games between Class A Kannapolis, High A Winston-Salem and Double-A Birmingham in 2025.
Schultz, the team’s first-round pick in 2022, went a combined 4-5 last season with a 4.68 ERA in 17 starts for Birmingham and Triple-A Charlotte. The lefty had 76 strikeouts in 73 innings. MLB.com ranks the Oswego East product as the No.49 prospect in baseball.
Fellow left-hander Smith, the team’s first-round pick in 2024, is ranked No. 72 on the MLB.com list. He went 3-3 with a 3.57 ERA in 20 starts for Birmingham in 2025. Smith struck out 108 and walked 56 in 75 2/3 innings.
Montgomery, Schultz and Smith are three of the 15 players from within the organization to be invited to big-league camp.
That group includes two more left-handed pitchers in Shane Murphy and Tyler Schweitzer, right-handers Mason Adams, Adisyn Coffey, Tyler Davis, Zach Franklin and Ben Peoples, outfielder Dru Baker, infielders Sam Antonacci, William Bergolla Jr. and 2023 first-round pick Jacob Gonzalez and catcher Michael Turner.
The Sox also officially announced the signings of right-handed pitcher Tyson Miller, left-handed pitcher Ryan Borucki, infielders Oliver Dunn, Tim Elko and LaMonte Wade Jr. and outfielders Dustin Harris and Jarred Kelenic to minor-league contracts.
All seven received nonroster invites to Sox spring training camp.
Borucki, a Mundelein product, went 1-3 with a 4.63 ERA in 39 combined relief appearances for the Pittsburgh Pirates and Blue Jays last season.
“Ryan Borucki is an arm that we feel like could fit into the bullpen,” Getz said. “He’s pitched in the big leagues, he’s been very effective against lefties, he’s developing some weapons to help combat righties as well.”
Spring training is around the corner. The first workout for Sox pitchers and catchers is scheduled for Feb. 10 in Glendale, Ariz. The first full-squad workout is set for Feb. 15.
