2026 Swing Decisions
Plate discipline detail · MLB hitters with 400+ pitches · 2026 regular season
Decisions score = z Heart swing% (adj.) + z Chase swing% (flipped), the same as on the overview. Heart = middle of the zone (Savant attack zones 1–9); chase = just off the edges (attack zones 21–29). Adj. heart swing% leaves out 3-0 pitches and off-speed/breaking pitches in 0-0, 1-0 and 2-0 counts.
Z-swing% and O-swing% use the rulebook strike zone, like FanGraphs. They are shown for reference and are not in the score.
Pool means (SD), 1,000+ pitches: heart swing% (all) 71.8% (6.0), heart (adj.) 77.0% (5.6), chase 25.8% (7.1), Z-swing 66.7% (5.7), O-swing 30.0% (5.8), Z minus O 36.7 pts (5.4), swing% 47.5% (4.8).
