MLB's Elite: Ranking the Top 10 Relievers of 2026

The State of Baseball Relievers in 2026

As spring training gears up, baseball fans are eager to dive into the latest rankings as it marks another season of excitement in Major League Baseball. Buster Olney's annual list of top talent gives us a closer look at the best relievers heading into 2026, a vital position that can make or break a team's postseason aspirations.

It's no secret: the strength of a bullpen can determine the trajectory of a season. This year, players were evaluated not for their past glories but for their anticipated performance this season—a refreshing focus that highlights the shifting nature of the game.

1. Mason Miller: The Pinnacle of Performance

At the top of the list, without question, is Mason Miller of the San Diego Padres. Last season, Miller was a true game-changer, consistently dazzling with strikeouts—he whiffed an astounding 45 out of 83 batters in his limited appearances. His fastball averaged a blistering 101.2 mph, the highest for any reliever in the league. This not only solidifies his dominance but showcases his evolution into one of the most significant pitchers in baseball.

Preller's decision to trade for Miller raised eyebrows, especially given that he was willing to part with high-caliber prospect Leo De Vries. Yet, the return on investment speaks volumes; Miller's performance after joining the Padres further validated the gamble. In a crucial playoff series against the Cubs, he struck out eight of the nine batters faced, reaffirming his status as a star in the making.

2. Edwin Diaz: Consistency Meets Expectation

Taking the second spot is Edwin Diaz of the Los Angeles Dodgers. Diaz may have faced challenges in previous seasons, but he bounced back spectacularly last year, offering a glimpse of the all-star we once knew. The Dodgers outbid their competition to bring him onboard, and it seems the investment is paying off. With a .502 OPS against and 98 strikeouts in 661/3 innings, Diaz appears primed for another stand-out year in the bullpen.

3. Jhoan Duran: The New Ace on the Block

Jhoan Duran from the Philadelphia Phillies occupies the third spot on the list. Duran's emergence as a force within the league is underscored by his 100.6 mph average fastball and a groundball percentage that registers at 65%. The dual threat of dominating strikeouts while limiting hard contact makes him an invaluable asset as teams look to maximize defensive efforts.

4. Aroldis Chapman: The Comeback Story

Aroldis Chapman, of the Boston Red Sox, brings experience and renewed reliability, earning him the fourth slot on this prestigious list. At 37, Chapman showcased remarkable control last season, achieving the lowest walk rate of his career. His presence in the bullpen mirrors the kind of savvy that teams strive for—where experience complements skill.

5. Cade Smith: The Steady Performer

Cade Smith from the Cleveland Guardians rounds out the top five. Following a notable absence of closer Emmanuel Clase, Smith stepped into the role effortlessly, flaunting a temperament often compared to the likes of Mariano Rivera. His strikeout numbers affirm his capability to perform under pressure, which is quintessential for a reliever working in high-stakes situations.

6. Andres Munoz: A Consistent Weapon

Andres Munoz of the Seattle Mariners makes his mark at sixth place, continuing a streak of excellence that puts him consistently above the competition. Despite occasionally heart-pounding moments during saves, his strikeout rates and minimal home runs allowed last season encapsulate the kind of production a team needs to feel confident heading into the postseason.

7. Abner Uribe: Nightmare for Hitters

The seventh position goes to Abner Uribe from the Milwaukee Brewers. With an astounding ERA+ of 249, Uribe poses a genuine threat to opposing batters through his unorthodox delivery and sharp breaking stuff. His impressive numbers against left-handed hitters further underline his place among elite relievers this season.

8. Robert Suarez: A Late Bloomer

Robert Suarez, of the Atlanta Braves, has proven that consistent performance isn't a thing of youth. In his four full seasons thus far, Suarez has proved his worth as a reliable reliever. The Braves' investment in him reflects a commitment to strengthening their bullpen, a wise move heading into a new season.

9. Devin Williams: A Change of Uniform

Devin Williams, now with the New York Mets, brings his legendary changeup with him as he reunites with former mentor David Stearns. Structure and stability are crucial for Williams as he navigates his place in the bullpen; his success will be a key storyline for the Mets this season.

10. Josh Hader: Legacy on the Line

Finally, Josh Hader, playing for the Houston Astros, claims the tenth spot. His recent setbacks don't overshadow the sensational career he has built, making his recovery essential for Houston's success this season. Hader's trajectory is a salient reminder of the razor-thin line between glory and obscurity in professional sports.
