Red Sox Reportedly Interested In Reliever With Extensive Late-Inning Experience

The Boston Red Sox are said to be interested in a reliever they’ve seen many times.

Free-agent righty Seranthony Dominguez is a name Boston has checked in on, Red Sox insiders Chris Cotillo and Sean McAdam of MassLive reported Wednesday.

Dominguez has spent the last season-and-a-half in the American League East following a years-long run in Philadelphia. He was sent to the Baltimore Orioles at the 2024 trade deadline, and remained there until the O’s dealt him to the Toronto Blue Jays at this year’s deadline.

The 31-year-old has 40 saves and 78 holds across 322 big league appearances, including a career-high 16 saves as a rookie in 2018. But control has been an occasional issue — he led the league in wild pitches in 2025 — which has impacted his ability to be a set-and-forget closer.

However, his pitch mix and ability to dominate hitters in stretches have tantalized contenders long enough to tolerate the hiccups. Further, Boston’s bullpen, as currently constructed with Aroldis Chapman, Garrett Whitlock and Justin Slaten, would not necessarily need to lean on Dominguez to routinely operate as a high-leverage arm.

Any contender will be looking at players with Dominguez’s track record as they build out their bullpen. It doesn’t take a ton of squinting to see why the idea of adding him to the mix is on Craig Breslow’s radar.

MLB Trade Rumors estimates Dominguez’s deal to come in around two years, $18 million. The reliever market has been hot already, so he could move quickly.
