Across 62 2/3 innings split between the Baltimore Orioles and Toronto Blue Jays in 2025, Chicago White Sox relief pitcher Seranthony Dominguez pitched to a 3.47 ERA and 1.28 WHIP with 79 strikeouts, four wins, and two saves. The White Sox rewarded Dominguez with a two-year, $20 million contract in free agency, and the 31-year-old appears poised to open 2026 as Chicago's primary closer. Dominguez has prior ninth-inning experience, as he's logged 40 saves across 322 career big-league appearances. He also posted a stellar 30.3% strikeout rate in 2025, so he's demonstrated the type of swing-and-miss stuff that teams typically look for in a closer. However, control has been a persistent issue for Dominguez, and he recorded a career-worst 13.8% walk rate in 2025. He's also been prone to giving up the long ball at times in his career, allowing a 1.84 HR/9 across 58 2/3 innings in 2024. While the White Sox are slowly getting better, they're still a team that has averaged 54 wins over the past three seasons and may not provide Dominguez with many save opportunities in 2026. Dominguez is a veteran arm that the White Sox chose to invest in over the winter, which could mean he will be afforded a long leash as the team's closer. As a low-cost ninth-inning option with a current average draft position of pick 289, he should hold some appeal for fantasy managers. However, managers should take note that Dominguez could hurt them in the ERA and WHIP categories, and poor team context could ultimately suppress Dominguez's ability to rack up saves.--Will Brady
