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.
