Seranthony Domínguez Fantasy Stats

The Chicago White Sox traded reliever Seranthony Dominguez, outfielder Nolan Jones, and catcher Boston Smith to the Seattle Mariners in exchange for right-hander Luis Castillo, according to Jeff Passan of ESPN. Dominguez signed a two-year, $20 million contract with the White Sox this offseason to be the team's closer. He struggled as the team's closer earlier in the season, converting just 12 of 17 save opportunities and eventually lost the job to Grant Taylor and Sean Newcomb in June. The 31-year-old owns a 3.99 ERA, 1.33 WHIP, and 47 strikeouts across 38 1/3 innings. With Andres Munoz locked in as Seattle's closer, Dominguez will be used mostly in leverage situations. Fantasy managers can move on from Dominguez outside leagues that reward saves and holds, as he is third in the pecking order for save chances behind Munoz and Jose A. Ferrer.

Chicago White Sox closer Seranthony Dominguez earned his 12th save on Sunday against the Los Angeles Dodgers, where he entered the game with a three-run lead and allowed one earned run on one hit, two walks, and two strikeouts. It was another shaky outing for Dominguez, where he has now pitched to the tune of a 1.19 WHIP and 3.81 ERA with 31 strikeouts in 26 innings pitched, and has converted on 12 of his 15 save opportunities. His underlying data and control are where things get a bit worrisome, evidenced by his 4.92 xERA, 90.5 mph average exit velocity (16th percentile), and 12.4 percent walk rate (14th percentile). He is not pitching particularly well, although the surface numbers would indicate it's been average, and when you combine that with the emergence of Grant Taylor of late, where he's converted on a few save opportunities, and Bryan Hudson and Jordan Leasure combined with seven save opportunities on the season, the line is getting very thin for Dominguez. Dominguez is still likely the closer to own for the time being, as the White Sox paid him a two-year, $20-million contract during the offseason to be the closer; however, the White Sox are competing (38-32) and sit atop the AL Central. For those rostering Dominguez, it's important to keep tabs on how he's used in the coming weeks and start preparing contingency plans.

Chicago White Sox relief pitcher Seranthony Dominguez closed out his team's 3-1 win on Monday over Minnesota, and he seems to have shaken off his struggles from earlier this month. Dominguez turned in back-to-back scoreless innings on Sunday and Monday after allowing two runs in each of his two previous appearances. On the season, the 31-year-old has 11 saves in 14 opportunities with a 4.35 ERA and 5.59 FIP. He has held opponents to a .192 average, but has a 1.26 WHIP since he has issued 11 walks in 20 2/3 innings. Dominguez hasn't exactly been a shut-down, elite option as a closer, but he should have a chance to claim more saves for Chicago, making him a good addition from the waiver wire if he's available. Bryan Hudson and Grant Taylor both appeared as setup men before Dominguez on Monday, and they would likely be next in line for saves if Dominguez struggles again. For now, though, he seems to have re-secured his role at the back end of the White Sox bullpen, making him worth a roster spot in most standard-sized leagues.

Across 14 2/3 innings (18 games) so far this season, Chicago White Sox closer Seranthony Dominguez has recorded a 3.68 ERA, 1.16 WHIP, 19 strikeouts, and eight saves. The 31-year-old has been particularly locked in of late, allowing just one earned run while logging 11 strikeouts and five saves over his last nine appearances. Control continues to be an issue for Dominguez, as he currently owns a 14.3% walk rate after posting a 13.8% walk rate in 2025. However, his strikeout rate is also north of 30% for the second straight season, which helps mitigate the damage of his free passes. Dominguez appears to have a firm hold on the ninth-inning role for the White Sox and should be rostered across all fantasy formats.

Across 13 innings so far in 2026, Chicago White Sox closer Seranthony Dominguez has pitched to a 4.15 ERA and 1.31 WHIP with 16 strikeouts and seven saves. The 31-year-old is prone to the occasional blow-up outing, as he's logged three appearances this season where he's allowed at least two runs. Dominguez owns both an elevated walk rate (15.5%) and an elevated HR/9 (2.08), a dangerous combination for his ERA. Still, the veteran right-hander has struck out 27.6% of the batters he's faced so far this season and remains locked in to the ninth-inning role in the White Sox bullpen. He's also currently riding a bit of a hot streak, as he's allowed just one earned run since April 16. In any league where he may have been dropped, Dominguez should be targeted on the waiver wire.

Chicago White Sox closer Seranthony Dominguez had a much-needed clean ninth inning in Thursday's 4-1 White Sox victory over the Arizona Diamondbacks. He pitched a clean frame, striking out two batters and not allowing a base runner, while only throwing 12 pitches (eight for strikes). Dominguez has now converted on his last two save opportunities after a rough outing on April 16 against the Tampa Bay Rays, where he had his second blown save of the season. On the season, Dominguez has now converted five of his seven save opportunities, and his two blown saves are the only runs he has allowed all season (five total). Because of those two blow-up outings, Dominguez owns a 5.00 ERA and 1.56 WHIP, which isn't great, but based on the scarcity of solid closers in MLB right now, Dominguez appears to be rising up the ranks after converting with clean outings in his last two opportunities. While the volume for saves may not be there for the White Sox (currently 10-15 on the season), Dominguez appears to have a firm grasp on the closer opportunity when situations arise; he just needs to continue to capitalize on those opportunities.

Chicago White Sox relief pitcher Seranthony Dominguez could be on a short leash after another tough outing on Thursday. Dominguez took the blown save after allowing three runs on two hits over 0.1 innings of work. He cleaned up his act on Saturday with a scoreless inning, but walked two batters over his inning of work. The right-hander has blown two saves and has a horrendous 7.50 ERA and a 1.83 WHIP over his six innings of work. He'll likely remain in the closer role for now, with the White Sox not having much competition for saves in their bullpen right now.

Chicago White Sox closer Seranthony Dominguez took the loss on Thursday against the Tampa Bay Rays and got tagged with his second blown save of the season. Dom nguez has now converted three of his five save opportunities. In Thursday's outing, Dom nguez entered the contest with a 3-2 lead, allowing three earned runs on two hits and one walk in 1/3 of an inning pitched. Dom nguez's other blown save came earlier in the season against Milwaukee and was also a blow-up type of outing, where he allowed two earned runs on one walk and two hits. He now has a 7.50 ERA and 1.83 WHIP through seven appearances. All five of his earned runs allowed came in the two blown save opportunities. The White Sox do not have much competition for bullpen arms to dethrone Dom nguez as closer just yet; however, he is running on thin ice and could be in jeopardy of losing the role if he doesn't provide more consistency moving forward. Fantasy managers who drafted Dom nguez as their back-end closer may want to begin to think of potential contingency plans on the off chance the White Sox do decide to try someone else out.

Chicago White Sox right-hander Seranthony Dominguez tallied his second save of the season on Thursday in the White Sox's 2-0 victory over the Kansas City Royals. He had a clean ninth inning, allowing one walk and striking out two Royals batters. Dominguez has now secured two saves in three total opportunities after a disappointing effort in his first save chance, where he allowed two earned runs in 1/3 innings against the Milwaukee Brewers back on March 29. Since that blown save, Dominguez has recorded three converted on three consecutive scoreless outings and has racked up a win and two saves in that time, and appears to have a clear grip on the closer role for the White Sox so long as he keeps converting his chances to close out games. On the season, Dominguez owns a 3.86 ERA and 1.50 WHIP with five strikeouts and three walks in five appearances.

Chicago White Sox relief pitcher Seranthony Dominguez is set to open the 2026 season as his team's primary closer. The 31-year-old signed a two-year contract with Chicago this past winter after posting a 3.16 ERA and 1.28 ERA with 79 strikeouts across 62 2/3 innings split between the Baltimore Orioles and Toronto Blue Jays in 2025. Dominguez recorded an impressive 30.3% strikeout rate, but he also allowed an elevated 13.8% walk rate. While Dominguez lowered his HR/9 to 0.72 in 2025, he allowed an elevated 1.84 HR/9 in 2024. If his struggles with the long ball return in 2026, his tendency to issue free passes could impact his ERA. Still, Dominguez should have an extended runway in the ninth inning in Chicago, and he's consistently demonstrated an ability to generate strikeouts throughout his MLB career. He may not have high-end upside, but Dominguez could be an undervalued source of saves and strikeouts for fantasy managers in 2026.
