The evolution of pitching in baseball reveals a paradox: pitchers are throwing harder than ever, yet they're relying less on fastballs. Notably, Padres reliever Miller leads the league in average fastball velocity at 101.3 mph but employs his fastball just 42% of the time—significantly down from previous seasons. The trend across Major League Baseball sees fastball usage drop nearly 10% over the last decade, with the average fastball reaching 94.4 mph in 2026, the fastest on record. While power pitching persists, the strategy of diversifying pitch types, especially favoring sliders, is becoming more common among strikeout artists.

By the Numbers
  • Miller's average fastball velocity: 101.3 mph.
  • MLB average fastball in 2026: 94.4 mph.
  • Fastball usage league-wide: 46.7%, down from 56.7% a decade ago.
Yes, But

Although Miller's success challenges the notion that the fastball is becoming obsolete, many pitchers are successfully blending their fastballs with other pitch types, particularly sliders, to stay effective. This paradigm shift has raised questions about the traditional role of fastballs in pitching strategies.

State of Play
  • Seven of the top hard-throwing relievers have decreased their fastball usage in the past year.
  • This season, 180 pitchers have thrown a pitch 98 mph or faster, highlighting the prevalence of elite velocity.
What's Next

As pitchers continue to adapt by using their fastballs less frequently, hitters are developing new strategies and technologies to cope with finding an edge against increased pitch speeds and diverse pitch selections. This could result in fluctuating pitching tactics as batsmen adjust their approaches.

Bottom Line

The game of baseball is witnessing a tactical evolution where speed alone is no longer enough. The strategic decline of fastball reliance and rise of pitch variety reflects the adaptive nature of modern hitters and pitchers, shaping the future of the sport.
