The 2025 fantasy baseball season is primed for action, with teams shaking up their bullpens ahead of spring training. Notably, Emmanuel Clase is projected to lead the saves chart with 41, flanked by elite arms like Josh Hader and Raisel Iglesias, both with 36. The American League features exciting closer situations, particularly in Oakland with Mason Miller, who showcases an impressive 101 mph fastball and a staggering strikeout rate that could redefine the closer role. In Baltimore, Félix Bautista returns from injury, hoping to reclaim the top closer spot after a stellar 2023, while the Red Sox juggle a mix of veterans and upstarts vying for save opportunities.

As teams finalize their rosters, keep an eye on potential waiver wire gems. For instance, the Royals’ Carlos Estévez might reclaim closing duties, while in Detroit, Jason Foley's lower strikeout rate raises concerns about his job security. The fantasy landscape is shifting rapidly, and savvy managers will track these developments closely to optimize their rosters ahead of the draft.
