Through 21 appearances, Miller's 0.96 ERA and 0.64 WHIP put him in conversation with Eric Gagne's 2003 Cy Young. His 18.32 K/9 leads all qualified MLB pitchers, and his 101.3 mph average fastball is the hardest of any reliever in Statcast tracking history. The 2.41 BB/9 walk rate stays elite even at that velocity tier. A 0.72 xERA suggests the early run prevention is sustainable. The only real risk is workload: he's on pace for 75-plus appearances, and 100-plus mph fastball usage at that frequency has no comparable precedent.
