Notes
	Mason Miller solidified himself as one of baseball's most dominant relievers in 2025, posting a sub-3.00 ERA with a staggering 44.4% strikeout rate and elite bat-missing ability that ticked up even further after his move to San Diego. His year-over-year gains in K% (41.8% in 2024 to 44.4% in 2025) came with louder contact suppression, as opponents hit just .139 overall with a .493 OPS. Miller is a high-volume saves source with league-best ratios, firmly cementing him as a top-tier fantasy closer and one of the safest bullpen anchors on draft day. Kelly Kirby - FantasyPros
