MLB American League: Will Mason Miller Win Reliever of the Year?
Major League Baseball (MLB) annually presents the best relief pitchers in the American League (AL) and National League (NL) with the Reliever of the Year Award.
The AL accolade, known as the Mariano Rivera AL Reliever of the Year Award, was introduced in 2014, replacing the Delivery Man of the Year Award.
Since then, many of the finest relief pitchers in the MLB have accepted the honor, such as Craig Kimbrel, Kenley Jansen, Josh Hader, Devin Williams, and Ryan Helsley.
However, if Mason Miller’s recent performance is anything to go by, a new name might soon be added to the list, but he faces strong competition in the league.
Keep reading to learn if Mason Miller is likely to win Reliever of the Year for the MLB American League 2025 season.

The trajectory of the odds for this BEO bet indicates it is most probable that Mason Miller will win Reliever of the Year for the MLB American League 2025 season ::: Discover the latest Bet Entertainment Odds predictions for this market.
Mason Miller is the Frontrunner
Mason Miller has developed a reputation in the AL for being an exceptional closer, especially in the 2024 season, as he achieved an impressive ERA of 2.49 with the Oakland Athletics.
While his performance hasn’t stood out as much as last year, he continues to be an elite relief pitcher, which is why BEO betting odds are showing he is a firm frontrunner for Reliever of the Year in 2025.
However, his recent transfer to the San Diego Padres in the National League may impact his eligibility for the accolade, allowing another player to accept the award instead.
Andres Muñoz is a Contender
Speaking of elite players, Andres Muñoz’s name is in the mix for Reliever of the Year for 2025, as his numbers are nothing short of impressive.
As of August 2025, he has a 1.40 ERA and a 0.96 WHIP across 45.0 innings for the Seattle Mariners.
He is a challenging competitor for hitters to face on the field, as he has a high strikeout rate of 57 in 45.0 innings.
Thanks to his consistent performance throughout the 2025 season, Muñoz is in a strong position to win the accolade this season, but he can’t afford to suffer a drop in form, as other AL players are hot on his heels on the leaderboard.
Jeff Hoffman Stands a Chance
As of August 2025, Jeff Hoffman is leading the AL for saves, placing him in a solid position for Reliever of the Year this year.
In addition to being one of the best closers in the MLB, he has achieved a high strikeout rate of 12.2 per 9 innings, proving he can dominate many hitters he faces throughout the season.
As he has secured a career high of 26 saves and has a stronger average strikeout rate and WHIP than his previous seasons, he might be a natural choice for Reliever of the Year this year.
However, another AL player could take home the accolade this season, such as Josh Hader, Emmanuel Clase, or two-time recipient Devin Williams.
Unfortunately, you will need to wait patiently to find out who will win Reliever of the Year, as the winner isn’t typically announced until after the World Series. It is often presented as part of various post-season awards, which are typically held in November.
