Seattle’s Munoz Dominates as Top MLB Relief Pitcher in 2025

SEATTLE, WA — As the 2025 MLB season approaches its halfway point, Seattle Mariners relief pitcher Andrés Munoz is making headlines as the standout closer in the league.

Munoz, who was among the first 10 relief pitchers selected on draft day, is tied for the league lead in saves and still boasts a perfect 0.00 ERA. With 17 saves so far this season, Munoz is well on his way to surpassing his career-high of 22 saves set last season.

With the Mariners leading the American League West, Munoz’s contributions are crucial. His 2.38 career ERA and impressive strikeout rate have made him a favorite among fantasy baseball players despite past injury concerns.

The Mariners’ bullpen has a collective 3.43 ERA, ranking 10th in the league. However, Munoz has handled the bulk of save opportunities, recording all but one of the team’s saves. Other notable pitchers in the bullpen include right-handers who are also making a fantasy impact.

Munoz leads all pure relief pitchers in ESPN standard fantasy points this season, further highlighting his value. Last season, Munoz and another pitcher ranked among the top-10 pitchers in scoring, despite allowing some earned runs.

As fans and fantasy players wonder if he can maintain this level of excellence throughout the season, Munoz continues to prove himself as one of baseball’s elite relief pitchers.

For those in search of other potential standout relievers, several less-publicized names are catching attention. Pittsburgh’s Carlos Santana has recorded multiple scoreless outings, while Chicago’s Palencia has stepped up with recent saves.

As the season unfolds, the focus on Munoz will remain strong, especially as he aims for another All-Star selection and possibly a shot at personal records.
