Who is the Most Reliable Arm in the 9th Inning?
The Verdict: Elite Stuff vs. Veteran Presence
- The 2026 relief pitcher landscape is dominated by high-octane arms like Mason Miller and Edwin Diaz, but veterans like Josh Hader and Aroldis Chapman continue to defy aging curves.
- With bullpens becoming more specialized than ever, the value of a strikeout artist who can also suppress the long ball—like Cade Smith—has never been higher.
- The Dodgers are betting big on Diaz to secure a three-piece, while the Padres have handed the ball to "The Reaper" to close out their title aspirations.
- What do you think? Is Mason Miller a lock for the best reliever in baseball, or will Edwin Diaz reclaim his crown in Los Angeles?
- Cast your vote: Who is your No. 1 high-leverage arm for the 2026 season?
- Sound off in the comments and let us know which bullpen move will decide the World Series!
Ranking the High-Leverage Monsters of 2026
Navigating the Volatility of the Bullpen
- We now turn to perhaps the most volatile, and fascinating, group in the sport: relief pitchers.
- Bullpens are built on razor-thin margins. One bad month can tank a season line, while one dominant stretch can vault a reliever into superstardom.
- This list is packed with failed starters turned high-leverage monsters, longtime closers chasing Hall of Fame cases, and flamethrowing late bloomers who are just scratching the surface.
- The voting panel for Just Baseball’s 2026 position rankings comprised of editors Ryan Finkelstein, Leo Morgenstern, Eric Treuden, and Joey Peterson, as well as Aram Leighton, Peter Appel, and Jack McMullen. Each panelist ranked players 1-25; the list below reflects the average of those rankings.

15. David Bednar | New York Yankees
The Command Specialist in the Bronx
- David Bednar’s surface numbers were strong, but the fact his 2.18 FIP undercut his 2.30 ERA and BB/9 was sub-3.0 tell a more impressive story than what first meets the eye.
- He was solid but not elite to start the year in his final run in Pittsburgh, and after a rough first couple outings in New York, which led to a demotion, Bednar regained command consistency and was awesome down the stretch.
- He is four-seamer dominant and that pitch averaged 97 mph with high ride, generating whiffs at the top of the zone, while his curveball (.172 opponent average) works beautifully off that fastball and yet again proved to be his best out pitch.
- The splitter was critical against lefties (.175 opponent average), giving him neutral splits and making him matchup-proof late in games for the Yankees.
13. Griffin Jax | Tampa Bay Rays
The Reliable Veteran Bridging the Gap
- Griffin Jax is the classic ERA/FIP divergence candidate. His 2025 ERA (4.23) masks elite bat-missing ability and a strong BB/9. The 2.51 FIP suggests sequencing and batted-ball variance drove the inflated ERA.
- His sweeper (.230 opponent average) and changeup (.182) remain legitimate putaway weapons. Tampa Bay’s usage flexibility adds value, as he can close or bridge.
- At 31 years old, Jax is as reliable and consistent a veteran as they come in the backend of a bullpen heading into 2026.
- The first half of the season could provide a friendly, low-pressure backdrop for Jax as he builds trade value for the deadline.
12. Trevor Megill | Milwaukee Brewers
Power-Overwhelm from a Steep Plane
- Trevor Megill’s profile is power-overwhelm. At 6-foot-8, he releases the ball from a steep plane, pairing 100-101 mph velocity with extension that shortens reaction time.
- The near-identical ERA (2.49) and FIP (2.50) indicate sustainability. 30 saves in limited innings underscore perfect deployment and immense trust in him.
- He doesn’t generate the same otherworldly strikeout rates relative to peers, but he limits damage and suppresses quality contact for the Brewers.
- The combination of role security and stable peripherals solidifies his top-12 placement.
11. Jeremiah Estrada | San Diego Padres
The Chitter Master in San Diego
- Jeremiah Estrada’s “chitter” (split-change hybrid) is one of the most unique pitches in baseball, and hitters went 9-for-71 against it with a 48% whiff rate and zero home runs in 2025.
- That single offering drove his strikeout rate north of 13 per nine. His 98-100 mph fastball tunnels effectively off the splitter.
- The 3.45 ERA didn’t pop, but the swing-and-miss and durability indicate reliability in leverage.
- Few relievers combine volume and bat-missing like Estrada, making him a vital piece for the Padres.
10. Abner Uribe | Milwaukee Brewers
Bounce Back Fuelled by Triple-Digit Sinks
- Abner Uribe’s incredible bounce back was rooted in command and elite homer suppression. His 99-mph sinker produced elite ground-ball numbers, and his slider (.134 opponent average) missed barrels entirely.
- Only four home runs allowed in 75+ innings was ridiculous. The 2.75 FIP suggests mild regression potential, largely tied to walk rate volatility.
- But a 50% ground-ball rate plus strikeouts is a stable formula. At 25, his stuff-driven ceiling rivals just about anyone.
9. Bryan Abreu | Houston Astros
The Underappreciated Strikeout Artist
- Three consecutive 100-strikeout seasons out of the bullpen define Bryan Abreu’s underappreciated dominance and reliability.
- The 2.39 FIP mirrors his 2.28 ERA, and his durability separates him from many current high-octane arms.
- He thrives in multi-inning leverage spots for the Astros. As a 28-year-old who could be on the trade block as a rental at this year’s deadline, he could potentially be the most sought-after arm.
- If he ever inherits full-time closing duties, his counting stats would skyrocket.
8. Devin Williams | New York Mets
The Airbender Reunited with Stearns
- Devin Williams’ 2025 ERA spike (4.79) was driven by sequencing and a few high-leverage blowups. The 2.68 FIP and still-elite strikeout rate show that his stuff, especially the changeup (“The Airbender”) remains devastating.
- His final 19 outings (two earned runs allowed) hint at a complete bounce back in a different New York borough in 2026.
- Reteaming with David Stearns, who ran baseball operations in Milwaukee when he developed, could offer an ideal change of scenery for the Mets' new arm.
- This is still a guy who has 465 career strikeouts in 297 innings – a massive 14.1 K/9.
7. Josh Hader | Houston Astros
Closing in on Hall of Fame Territory
- Even off an injury-shortened campaign, Josh Hader’s dominance remains unmatched. He limits hard contact and consistently suppresses batting average against.
- His strikeout rate still hovers near elite territory at 12.99 K/9. Durability questions linger, but when active, he compresses games into eight innings.
- He has 227 career saves, and if he can stay on the mound for another contract or two, the Hall of Fame case will be an intriguing one.
- In 2025, he posted a stellar 0.85 WHIP, showing he hasn't lost the ability to keep runners off the paths.
6. Aroldis Chapman | Boston Red Sox
The Renaissance of the Missile
- Aroldis Chapman’s renaissance was built on improved strike throwing (career-best walk rate of 6.6%) and contact suppression — just 28 hits allowed in 61.1 innings.
- The velocity remains premium, but command refinement sent him to the moon in 2025, boasting a ridiculous 1.17 ERA and 0.70 WHIP.
- Sustaining these numbers in his 38-year-old season is unlikely, but his peripherals suggest legitimate high-leverage viability remains for the Red Sox.
5. Andrés Muñoz | Seattle Mariners
The Slider of Death in the Pacific Northwest
- Andrés Muñoz is a premier fireballer, but it’s his slider (.109 opponent average, 50+% whiff rate) that is among baseball’s most devastating and unhittable offerings.
- Only two home runs allowed all year against 254 hitters is a testament to his elite barrel suppression.
- He has now had four straight years with an ERA+ of 135 or better, and he held opposing hitters to a .493 OPS in 2025.
- His ability to miss bats without issuing excessive walks pushes him into top-five certainty for the Mariners.
4. Jhoan Duran | Philadelphia Phillies
Uber-Rare Power Meets Ground-Ball Control
- After arriving on the mound with the most intimidating closing pitcher entrance routine, Jhoan Duran pairs a 100.6 mph average fastball with a 65% ground-ball rate.
- After being traded to Philadelphia at the deadline, he struck out 27 and walked just one hitter in 20 innings.
- This man doesn’t beat himself, and he hardly ever gets beat by a hitter. In September 2025, Duran made a statement against the Mets, striking out the side on some ugly swings.
- His 2.35 FIP confirms that he is one of the most dominant forces in the game.
3. Cade Smith | Cleveland Guardians
Cleveland’s Next Great Strikeout Artist
- Cade Smith has struck out 207 hitters in 149 career innings while allowing just five total home runs. For a guy who heavily relies on a four-seam fastball, that’s just insane.
- In 2025, opponents hit just .170 against his heater. The FIP under 2.00 compared to an ERA close to 3.00 tells us he should experience some positive regression this year.
- With Emmanuel Clase’s career in jeopardy, Smith will be given full-time closing duties in Cleveland, and the numbers could explode.
- Barring injury, Smith is on track for three straight 100+ strikeout seasons out of the bullpen.
2. Edwin Diaz | Los Angeles Dodgers
Rounding Out the Dodgers’ Death Star
- A three-time All-Star, Edwin Díaz’s second-best season in a Met uniform saw him allow just 37 hits and a .502 OPS in 66 innings in 2025.
- His fastball regained life, and the slider generated consistent chase. Now with the Los Angeles Dodgers, his leverage situations should remain high-impact but controlled.
- It will be interesting to see how Diaz lives up to his record-breaking contract in year one with the back-to-back defending champions.
- If he can be the guy the Dodgers paid for, he could be the piece to put them over the top as they hunt a three-peat.
1. Mason Miller | San Diego Padres
The Reaper Claims the Throne
- Overpowering is an understatement. Mason Miller, AKA “The Reaper,” comes at you with a 103-104 mph fastball that never seems to let up at all.
- Post-trade to San Diego, he allowed two runs in 23⅓ innings. What’s even more insane is that he held hitters to 4-for-65 with 42 strikeouts and zero extra-base hits down the stretch.
- The top 25 MLB hitters by OPS since 2024 are just 2-for-42 against him with 24 strikeouts.
- When healthy, no reliever combines strikeout volume, intimidation, and damage prevention at Miller’s level. He enters 2026 as the clear No. 1 on this list.
