Relief pitchers remain the most volatile assets in fantasy baseball, with little year-to-year correlation in rankings and frequent job turnover. In 2026, only five of the 11 relievers drafted in the top 100 on average — Mason Miller, Cade Smith, Jhoan Duran, David Bednar, and Aroldis Chapman — delivered on their draft cost. High-profile names like Edwin Diaz, Devin Williams, Ryan Helsley, Daniel Palencia, and Jeff Hoffman lost jobs or dealt with injuries, while Andres Munoz managed just 28 saves. The next tier, including Raisel Iglesias, Pete Fairbanks, Carlos Estevez, Ryan Walker, and Dennis Santana, also largely disappointed.
2026 Relief Pitcher Review
Statistical leaders from 2026 illustrate the unpredictability: Miller (70 IP, 1.67 ERA, 0.90 WHIP, 129 K, 38 saves), Smith (74 IP, 1.95 ERA, 0.96 WHIP, 107 K, 41 saves), Jacob Latz (72 IP, 2.13 ERA, 0.81 WHIP, 83 K, 30 saves), Louis Varland (78 IP, 1.27 ERA, 1.00 WHIP, 97 K, 35 saves), Bryan Baker (62 IP, 1.44 ERA, 0.91 WHIP, 63 K, 41 saves), Grant Taylor (84 IP, 2.25 ERA, 1.07 WHIP, 106 K, 10 saves), Mason Montgomery (68.1 IP, 2.88 ERA, 1.03 WHIP, 105 K, 18 saves), Bednar (69 IP, 2.47 ERA, 1.04 WHIP, 76 K, 35 saves), Paul Blackburn (85 IP, 1.59 ERA, 1.08 WHIP, 69 K, 1 save), Josh Hader (44.1 IP, 1.01 ERA, 0.76 WHIP, 55 K, 26 saves), Jhoan Duran (59 IP, 1.82 ERA, 0.99 WHIP, 84 K, 33 saves), and Didier Fuentes (73 IP, 2.45 ERA, 1.10 WHIP, 92 K, 1 save). Fuentes, a 21-year-old, may transition to Atlanta's rotation in 2027, potentially becoming a valuable SPaRP (Starting Pitcher as Relief Pitcher) in points leagues.
Biggest Breakout: Louis Varland
Varland emerged as an elite closer for the Blue Jays, posting a 1.27 ERA and 2.37 xERA over 78 innings. Increased velocity and a refined changeup with roughly 30 inches of drop complemented his 99 mph fastball and excellent curveball. He demonstrated high-volume durability without performance decline and enters 2027 as a consensus top-five fantasy closer.
Biggest Bust: Edwin Diaz
Diaz's 2026 season with the Dodgers was a disaster; he lost the closer role before requiring elbow surgery and never regained it. Despite a better postseason, his track record includes a 5.59 ERA in 2019 and multiple job losses with the Mets. With two years and significant money remaining on his contract, Diaz will likely open 2027 as the Dodgers' closer but carries substantial risk.
Rankings Movers for 2027
Rising: Varland; Jacob Latz (Rangers), who posted a 1.22 ERA and 44% strikeout rate over his final 38 appearances after a pitch-mix adjustment; Bryan Baker (Rays), who thrived with a heavy changeup usage despite worse strikeout and walk rates; Mason Montgomery (Pirates), who ditched his changeup for a sinker and dominated late in the season. Falling: Diaz; Devin Williams (Mets), who has a 4.65 ERA over 102.2 innings the past two seasons despite strong peripherals; Ryan Helsley (Orioles), who posted a 4.42 ERA over two seasons and missed most of 2026 with elbow issues. Helsley will compete with Felix Bautista for the closer role in 2027.
Offseason Preview: Teams Needing Upgrades
The Yankees, Marlins, Mets, Nationals, Royals, Tigers, Reds, Athletics, and Giants all have ninth-inning uncertainty. The Yankees may re-sign Bednar. The Marlins, after Pete Fairbanks' disappointing contract and Thoracic Outlet surgery, experimented with starters Sandy Alcantara and Eury Perez in high-leverage relief, a strategy they may continue. Alcantara could become a SPaRP cheat code in points leagues.
Top Impending Free Agents and Trade Candidates
Key free agents include David Bednar, Emilio Pagan (player option), Adrian Morejon, Raisel Iglesias, Bryan Abreu, and Kenley Jansen (team option). Morejon, with a 2.58 ERA and 27% strikeout rate over three seasons, draws interest as both a potential starter and elite closer. Trade candidates include Josh Hader (Astros) and Mason Miller (Padres). If the Padres trade Miller and lose Morejon, Bradgley Rodriguez (2.19 ERA, 2.37 xERA in 74 IP) becomes a top breakout candidate.
