Week 12 of the 2025 fantasy baseball season highlights the volatility at the closer position, prompting savvy fantasy managers to consider stashing backup options for potential saves down the stretch. With injuries and performance issues affecting several bullpens, including those of the San Diego Padres and Seattle Mariners, identifying closers who may be on a shorter leash becomes crucial.

Jason Adam of the San Diego Padres, who boasts a 1.54 ERA and 17 holds, is a prime candidate to take over if Robert Suarez falters. Similarly, Randy Rodríguez of the San Francisco Giants is positioned to leapfrog Camilo Doval, who has struggled recently. Other noteworthy mentions include Lucas Erceg of the Kansas City Royals and Bryan Abreu of the Houston Astros, both of whom have shown promise in their respective bullpens. Staying alert in this fluid environment can unlock hidden value in your fantasy roster as the season progresses.

This week's fantasy baseball waiver wire targets spotlight players emerging from the injured list and a promising rookie pitcher. Jacob Misiorowski, the Milwaukee Brewers' young starter, made an impressive debut with five no-hit innings and boasts strong Triple-A numbers. Jack Leiter from the Texas Rangers remains a streaming option despite his mediocre stats. Atlanta Braves' Grant Holmes is another solid two-start pitcher to consider. San Francisco Giants' Randy Rodriguez is a must-add reliever with remarkable strikeout rates. Alejandro Kirk of the Toronto Blue Jays is surging offensively, while Cincinnati Reds' Christian Encarnacion-Strand returns from injury ready to impact the first base position.

Meanwhile, keep an eye on Nick Kurtz of the Athletics, who has shown flashes of potential and recently returned from injury. Chicago White Sox's Chase Meidroth offers speed, while Evan Carter's hot streak since returning from the IL makes him worth the gamble for fantasy managers looking for an outfield boost.

Week 11 of the 2025 fantasy baseball season brings a focus on relief pitchers who could be valuable assets for teams struggling to secure saves. With uncertainty in many bullpens, savvy fantasy managers are seeking outclosers who may not be the primary options but are poised to step up at any moment.

Key names to consider include Randy Rodriguez of the San Francisco Giants, whose impressive strikeout ratio makes him an attractive stash behind Camilo Doval. Similarly, Bryan Abreu from the Houston Astros should be on managers' radars as he supports the established closer Josh Hader. Moreover, with Justin Martinez's unfortunate injury, Shelby Miller of the Arizona Diamondbacks could reclaim closing duties soon, making him another prudent acquisition. The landscape of relief pitching is volatile, and keeping an eye on emerging talent is essential for maximizing saves potential.
