Last year, the 26-year-old pitcher set the bar for strikeout numbers with the Oakland Athletics.
He plays at an elite level, as his fastball often reach 100 mph, leading to multiple swings and misses.
Not to mention, Miller had a rare 41.8% strikeout rate in 2024, as he totaled an incredible 104 strikeouts in 65 innings, making him the best reliever in the league.
As he has only played a small number of games in 2025, it’s hard to predict if he’ll take home the accolade this year.
However, his early performance suggests he’ll replicate his success on the field last season, as he’s made 14 saves within 25 appearances and had 43 strikeouts in 25.1 innings, as of June 2025.
Andrés Muñoz Could Win
Mason Miller will face tough competition from Andrés Muñoz for the award, as his early MLB American League 2025 statistics are impressive.
As of June 2025, the 26-year-old pitcher has wowed Seattle Mariners’ fans, as he has achieved a 1.30 ERA, 18 saves, and 36 strikeouts within 27.2 innings.
Plus, he has a low batting average of .106 and a 0.83 WHIP. Thanks to his elite performance early in the season, he received the award for American League Reliever of the Month for March/April 2025.
If he continues to play at the same standard or higher, there is a good chance he’ll be presented with Reliever of the Year in 2025. However, he must continue to make crucial saves for the Mariners if he wants to add it to his trophy cabinet at the end of the season.
As he often thrives under the greatest of pressures, he’s one player to watch in the league this year.
Jeff Hoffman is a Potential Threat
Jeff Hoffman is a top reliever in the sport, and a strong season could help him pick up the accolade.
As he signed a three-year contract to join the Toronto Blue Jays in 2025, he’s likely eager to make an impact during his second stint on the team.
The 32-year-old pitcher has proved a force to be reckoned with since his arrival, as he has achieved 17 saves, 43 strikeouts, a 5.70 ERA within 30.0 innings, and a 1.10 WHIP as of June 2025.
Many baseball fans believe he’s become a much more confident, versatile player, commenting that his splitter usage has increased and he’s throwing sliders much harder. If he continues to grow in confidence at the Blue Jays, he may win Reliever of the Year 2025.
