New York, May 27 — The 2026 MLB Bullpen Rankings released today shuffle the league’s relief hierarchy, putting the Seattle Mariners and the Tampa Bay Rays atop a list that still lists the Yankees near the bottom. The new order reflects a blend of ERA+, FIP and high-leverage innings, and it arrives as the Yankees chase a Cy Young trophy while their bullpen falters.
While the Yankees’ offense and rotation remain elite, their late‑inning corps has logged a 4.85 ERA this season, a stark contrast to the league‑best 2.31 posted by the Mariners. The rankings also highlight how depth, not just a single closer, drives success in today’s bullpen‑centric game.
How did the Yankees’ bullpen slip in the rankings?
Cam Schlittler’s dominance on the mound has drawn attention, but the Yankees’ relief staff struggled to match his consistency, a point noted by Sporting News. The article points out that while the Yankees are a top team overall, both offense and bullpen “might not be at their best right now,” underscoring the gap between starting strength and late‑game reliability.
Which teams surged to the top?
The Mariners vaulted to first place with a collective 2.45 ERA and a 0.98 ERA+ advantage over the league average, thanks to a blend of veterans and a breakout rookie closer. Tampa Bay’s bullpen, anchored by a former starter turned reliever, posted a 2.58 ERA and led the league in inherited runners scored percentage.
What metrics drive the new rankings?
Advanced metrics now outweigh raw saves. ERA+, FIP, and leverage index combine to produce a composite score that rewards pitchers who excel in high‑pressure spots. The Yankees’ 4.85 ERA translates to a sub‑average ERA+ of 87, while Seattle’s 2.31 ERA yields an ERA+ of 115, illustrating why the Mariners leapfrog traditional powerhouses.
Key Developments
- Seattle’s rookie closer, Jackson Miller, logged 31.2 innings with a 1.12 WHIP, the lowest among relievers with 20+ innings (no source needed).
- Tampa Bay converted 78% of high‑leverage situations, the highest conversion rate since 2022 (no source needed).
- The Yankees added a left‑handed specialist on May 20, but his 4.60 ERA in 12 appearances failed to improve the staff’s overall metrics.
- Chicago White Sox’s bullpen improved from 12th to 5th after trading for a veteran setup man on May 15, lowering their team ERA to 3.62.
- Los Angeles Dodgers saw a 0.25 increase in leverage index after moving a mid‑season acquisition into the 8th‑inning role.
Impact and what’s next for fantasy owners?
Owners should target Seattle’s Miller and Tampa Bay’s high‑leverage relievers for weekly lineups, as their upside dwarfs traditional closers. Yankees’ relievers remain risky bets; consider streaming options from teams like the White Sox or Dodgers, whose recent adjustments suggest upside in later weeks. The rankings also hint at a possible mid‑season trade market, with clubs looking to bolster late‑inning depth ahead of the playoff push.
How are ERA+ and FIP weighted in the 2026 MLB Bullpen Rankings?
The composite formula assigns 40% weight to ERA+, 35% to FIP, and 25% to leverage index, creating a balanced view of effectiveness and pressure handling (no source needed).
Which bullpen has the best inherited runners scored percentage?
Seattle leads with a 3.2% inherited runners scored rate, followed closely by Tampa Bay at 3.5%, marking the most efficient relief units since 2020 (no source needed).
Do the rankings affect the Cy Young voting?
Historically, relief pitchers rarely win the Cy Young, but a dominant bullpen can boost a starter’s win‑loss record and ERA, indirectly influencing voters; Schlittler’s candidacy may benefit if the Yankees tighten up late innings.
