The 2026 MLB regular season begins on March 25^th. Last season had many storylines, with tenured and rookie players having electric seasons. Baseball is the greatest sport in the world, and the upcoming season won’t disappoint. With a week before the 2026 MLB begin here are the top five relief pitcher rankings.

5. Jhoan Duran, Philadelphia Phillies

Duran has an elite arm and fastball out of the bullpen. Injuries plagued him during his first three seasons, but 2025 saw the reliever stay healthy and appear in 72 games. He finished the season with career-highs in innings pitched, saves, and WAR.

4. Cade Smith, Cleveland Guardians

Smith’s 2024 rookie season saw him become one of the game’s top setup men. He started last season in the setup role before becoming the team’s closer in late July. 2026 will be Smith’s first season as Cleveland’s closer, and he will be among the league’s top relievers in strikeouts and saves.

3. Andres Munoz, Seattle Mariners

Munoz finished last season as the undisputed closing option for the Mariners. He tied his career best mark with 64 appearances, while setting career highs in ERA, WHIP, saves (38), and WAR. He is in store for another high-usage season in 2026.

2. Edwin Diaz, Los Angeles Dodgers

Diaz has proven himself to be one of MLB’s premier relief pitchers. He’s had his fair share of rough seasons, but when he’s on, he’s elite. He joins the Dodgers in 2026 and will have every opportunity to lead the league in saves.

1. Mason Miller, San Diego Padres

Mason Miller possesses the most elite arm of any MLB relief pitcher. His triple-digit fastball is second to none, and this makes his secondary pitches very effective. 2026 will be his first full season in San Diego after being acquired during last season’s trade deadline. The Padres are due to regress, and if the team finds themselves in many close games, Miller will have the opportunity to reach career best marks in appearances, saves, and strikeouts.
