Johan Santana

A circle changeup widely called the best of its era, built entirely on looking exactly like the fastball.

Signature pitchCircle changeup

Santana’s 2000s peak ran on a circle changeup that scouts and hitters called the best of its era. Its deception came not from exotic movement but from identical arm action, release point, and effort, so hitters committed early and the ball arrived later and slower than they expected. He won the AL Cy Young unanimously in 2004 and 2006.

The signature pitch

A circle changeup launched with arm action, release point, and effort indistinguishable from his fastball, so the two looked like twins until the change arrived late and slow with fade down and away from righties. The weapon was the disguise: hitters committed to the fastball look and were left reaching for the fade.

Reference schematic

MLB.com calls the circle change the most common changeup grip: thumb and index in a circle on the inner side, the other three fingers over the rest of the ball. Held farther back in the hand, sometimes toward the palm, which is what takes the speed off.

The mental edge

The whole design was disguise. The Twins sent him to Triple-A in 2002 specifically to force-feed the changeup, where a coach made him throw one to nearly every hitter until he trusted it completely. The reputation cast it as a huge separation pitch, but the more useful lesson is cleaner: the deception, not a published gap, is what made it elite.

A real, sourced tension worth keeping: scouting lore cast the change as an enormous separation pitch, while tracking-era readings made the disguise look more important than any headline gap.

“I was challenging myself and forcing myself to take command of that pitch.”

The record

Two Cy Young Awards, 2004 and 2006, both unanimous — the writers could not find a reason to split a vote either year. Both seasons he led the league in run prevention and piled up strikeouts behind a fastball nobody feared and a changeup everybody did.
