Seranthony Domínguez: Last 2025 Oriole in World Series Run

BALTIMORE, MD — In a surprising twist, Seranthony Domínguez is the only player from the 2025 Baltimore Orioles still vying for a World Series title. This follows a significant fire sale that saw many Orioles players traded away. Domínguez has not only found a role with the Toronto Blue Jays but has also contributed to the Orioles’ acquisition of up-and-coming pitching prospect Juaron Watts-Brown.

Domínguez, who was the former closer for Baltimore, was among four relievers traded during the July 2025 deadline. Acquired from the Philadelphia Phillies the previous season, he quickly took over the closer spot after Craig Kimbrel was released. In his early games with the Orioles, he had a solid 2.57 ERA over 14 innings, with 17 strikeouts and six saves. However, his performance fluctuated, and by the end of the 2024 season, his ERA ballooned to 6.23, losing his closer role in the process.

The 2025 season began with promise as Domínguez recorded nine consecutive scoreless appearances. Yet, by late April, he faced struggles resulting in an 8.31 ERA through May. A breakthrough occurred in June when he increased his use of a new splitter pitch. This adjustment helped him achieve a 1.33 ERA and 28 strikeouts over 20 innings leading up to his trade on July 29.

The trade took place during a doubleheader against the Blue Jays. Ironically, Domínguez pitched for the Orioles in the first game before being traded to Toronto for 23-year-old right-handed prospect Juaron Watts-Brown. This deal proved beneficial for Baltimore as Watts-Brown, known for his exceptional slider, emerged as a promising talent, ranking as the Orioles’ No. 13 prospect.

Since joining the Blue Jays, Domínguez has adapted to a setup role behind closer Jeff Hoffman. During the regular season, he posted a 3.00 ERA along with 25 strikeouts in 21 innings and significantly reduced his home run rate. As the Blue Jays progress toward the World Series, he continues to make meaningful contributions, although he faced challenges with key home runs allowed in playoff moments.

Domínguez’s legacy is developing; while he may simply be seen as another inconsistent reliever from Baltimore’s past, he stands on the brink of being the first player to win a championship in the same season he played for the Orioles. Alternatively, he may be remembered as a crucial part of Baltimore’s future along with Watts-Brown.
