The best fantasy relief pitchers so often live on the waiver wire instead of on rosters. In fantasy baseball leagues top set-up relievers wait in the wings, particularly in leagues that count saves and ignore holds. Stashing a talented arm for future save possibilities, or for streaming strikeouts and ERA/WHIP help, shouldn’t be ignored either.
Setup relievers with elite strikeout rates and microscopic walk rates are still widely available but deliver massive value in holds or saves+holds leagues. Here’s a breakdown of some of the best names that are likely available in your league.
Taylor is establishing himself as a premier breakout candidate in the White Sox bullpen, fueled by a four-seam fastball that consistently touches triple digits and averaged 98.7 mph last season. Through 13 innings in April 2026, he has maintained a dominant 34.1% strikeout rate and a stellar 1.41 FIP. His electric stuff, including a high-whiff fastball/curveball combination, makes him a multi-inning weapon who should be rostered for his elite strikeout upside and ratio stability.
Taylor has appeared in 10 games — he opened 4 of them and pitched in the 6th or 7th inning in the other six. He deserves 8th inning looks.
Sabrowski has emerged as a major high-leverage asset, already leading MLB with 9 holds. His peripherals are staggering, highlighted by a 41.3% strikeout rate and a 2.29 FIP over his first 11.2 innings. While his 3.09 ERA is solid, his underlying metrics suggest even more dominance is possible, making him a priority add for managers in holds-heavy formats.
Nunez has quickly ascended bullpen hierarchy in Baltimore by missing bats and with exceptional command. In 12.1 innings this season, he has struck out 15 batters while issuing only two walks, resulting in a microscopic 0.65 WHIP and a 1.46 ERA. His 32.6% strikeout rate and elite 4.3% walk rate provide a rare combination of high-ceiling production and ratio protection for fantasy managers.
Despite an elevated 4.82 ERA, Uribe’s peripherals signal that a massive turnaround is imminent. He continues to baffle hitters with a triple-digit sinker and has maintained a 30.0% strikeout rate early in the 2026 campaign. His 2.97 xFIP and 1.50 FIP strongly suggest his current results are due for significant positive regression, keeping him as a top-tier "closer-in-waiting" stash behind Trevor Megill.
Whitlock has successfully transitioned into a premier setup role, frequently working the 8th inning to bridge the gap to closer Aroldis Chapman. Through his first 9 innings of 2026, he has posted a 2.00 ERA and 12 strikeouts while maintaining excellent control. His ability to pound the zone, throwing 52.2% of his pitches in the strike zone, paired with high whiff rates on his slider and changeup, solidifies his role as a high-volume holds source while providing a stable ratio.
I keep going back to the well here, but Jax remains a high-quality "stuff" play in the Rays' high-leverage committee, despite some early-season volatility in his surface stats. Projections remain bullish on his ability to return to elite form, with an expected 32.0% strikeout rate and an elite 2.60 FIP. His ability to generate chases and whiffs — ranking near the top of the league in both categories in 2025—makes him a "screaming value" for managers seeking punchouts.
In fantasy football, “handcuffing” running backs on the same time is a popular concept. Baker and Jax might make good bullpen handcuffs in fantasy baseball. Baker is a critical component of the Rays' flexible bullpen strategy and has already capitalized on save opportunities with 4 saves in early 2026. He features a 25.7% strikeout rate and a disciplined 8.6% walk rate through 8.1 innings. With an underlying 3.62 FIP that outperforms his 4.32 ERA, Baker is a versatile target who provides a mix of holds, saves, and solid per-inning production.
These arms deliver elite per-inning production and future closing upside at a fraction of the cost of established closers. Each of them is worth monitoring, stashing or streaming depending on the specifics of your fantasy baseball league. But they should all continue to appear in high-leverage situations and return plenty of whiffs at a minimum.
