Nick Mariano’s weekly closer report arrives just as fantasy managers scramble to lock down the final weeks of the season, offering a snapshot of the most volatile bullpen situations across the league.
The rankings are divided into tiers, each spotlighting relievers who not only dominate in save opportunities but also present upside for ratio categories, making them prime waiver‑wire targets.
Among the standout movers, Texas right‑hander Jacob Latz has surged to a 52 % roster percentage after a string of high‑leverage outings that have left batters guessing.
Veterans such as Paul Sewald, Pete Fairbanks, Kenley Jansen and Gregory Soto hover in the 50‑70 % band, a sweet spot for shallow‑league owners seeking reliable closers without overpaying.
The Minnesota Twins’ Yoendrys Gomez has caught the eye of analysts thanks to a noticeable jump in velocity and tighter command, trends that have translated into more strikeouts and fewer walks.
In San Francisco, Caleb Kilian has been anointed the primary closer, while Ryan Walker continues to serve as the team’s fireman, stepping into high‑pressure spots when the game demands it.
Elvis Alvarado of the Athletics has seen his save total climb, though a recent solo home run allowed reminds managers that consistency still matters.
Alex Lange remains the Kansas City Royals’ reserved closer, weathering a couple of rough outings but still expected to anchor the ninth inning when the situation calls for it.
Other arms making noise include Chicago Cubs reliever Jacob Webb, who secured a recent save, and veteran Caleb Thielbar, who finds himself in the late‑leverage conversation.
Grant Taylor of the White Sox still appears to be the safest bet for saves, even after a few hiccups, while Tony Santillan of Cincinnati has posted back‑to‑back saves and a velocity uptick that suggests he could become a more prominent option.
Boston’s Garrett Whitlock offers a hedge against Aroldis Chapman’s hamstring woes, and Bryan Abreu remains the go‑to closer for the Astros when Josh Hader rests.
The Padres are monitoring Adrian Morejon and Jason Adam as potential fill‑ins while Mason Miller is on leave, and the Cardinals’ Riley O’Brien is struggling after surrendering eight runs in his last 30 days.
Meanwhile, Angels prospect Ryan Zeferjahn has dazzled with an 11‑8 strikeout‑to‑walk ratio over his last six appearances, showcasing a high‑risk, high‑reward profile.
Brad Lord of the Mariners has quietly compiled a 1.11 ERA since May 8, pairing it with a surge in strikeouts that could make him a sleeper in deeper formats.
The debut of Daniel Espino, who finally stepped onto the mound after multiple shoulder surgeries, resulted in a pair of strikeouts that hint at a potential late‑season impact.
Strategic Takeaways for Shallow Leagues
For managers in leagues with limited roster spots, the key is to prioritize relievers who combine save potential with ratio upside, as the data shows that a handful of weekly waiver adds can shift the balance of power in the standings.
