Illegal Pitch
Ang illegal pitch ay anumang delivery na lumalabag sa mga rule — pinakakaraniwan ay pitch na labas sa legal na arc window, bolang tinapon nang may spin, o release mula sa illegal na posisyon.
Kasama sa mga karaniwang illegal-pitch na paglabag sa slow pitch: sobrang mababa ang arc (sa ibaba ng 6 talampakan) o sobrang mataas (higit sa 12 talampakan); ang sinasadyang pagbibigay ng spin (matalas na pag-ikot ng wrist sa release); two-handed na delivery; o pagtapon mula sa labas ng rubber. Kapag tinawag ang illegal na pitch, maaaring kunin ng batter ang pitch bilang ball o piliing mag-swing. Natututunan ng mga pitcher na basahin ang tendencies ng umpire at i-dial in ang arc nila para manatiling legal at protektahan ang team nila mula sa libreng counts.
If an umpire calls your pitch illegal, ask in particular which rule was violated. This means arc, speed, or release. This means. As a result, you can fix the correct issue rather than changing the wrong thing.
Film your practice pitches from the side with a reference marker at 6 and 12 feet to build a visual library of your arc heights across different speeds and effort levels.
Example
Umaakyat ang pitch sa 14 talampakan — malayong lampas sa maximum — at agad na sini-senyales ng umpire na "illegal pitch," binibigyan ng ball ang batter.
How it shows up on video
An illegal pitch is identifiable on video by comparing the ball's peak height against a known reference. This means a flat delivery that never visibly rises above the batter's helmet is almost certainly below 6 feet. A spin-enhanced pitch shows rapid rotation visible as a visible seam blur or an unusual lateral curve that a standard arc would not produce. The umpire's call is definitive, but video review helps pitchers self-diagnose between games.
Common mistakes
- Throwing too hard and flattening the arc below 6 feet in the excitement of a key at-bat, the most common illegal-pitch type in competitive slow-pitch
- Adding wrist-snap to generate extra spin for movement, not realizing the association classifies intentional spin as an illegal pitch
- Failing to come to a complete stop with both feet on the rubber before starting the delivery. This some associations classify as an illegal start position
- Pitching from the wrong distance after moving to a different league, unknowingly using 46-foot mechanics from a 50-foot rubber or vice versa
In SwingVantage Motion Lab
SwingVantage can flag pitch deliveries where the estimated arc height falls below the 6-foot threshold from video analysis. This gives pitchers objective feedback to self-correct before a game situation.

- Legal DeliveryAng legal delivery sa slow-pitch softball ay pitch na inila-release nang underhand na may maayos at tuloy-tuloy na motion at dumarating sa loob ng kinakailangang arc height — karaniwan ay sa pagitan ng 6 at 12 talampakan — sa itaas ng plate.
- Arc Height RegulationItinatakda ng arc height regulation ang kinakailangang minimum at maximum na taas na dapat abutin ng slow-pitch na delivery — karaniwan ay 6 hanggang 12 talampakan — para tawaging legal na pitch.
- Strike Zone – Slow-PitchAng slow-pitch strike zone (USA Softball) ay ang espasyo sa itaas ng home plate sa pagitan ng likod na balikat ng batter at harap na tuhod; ang strike ay legal at maayos na naka-arc na pitch na dumadaan sa zone na iyon sa flight, habang ang mga mat-play na liga naman ay tinatawag na strikes ang mga pitch na lumalapag sa plate o strike mat.
- Pitching RubberAng pitching rubber ay ang puting rubber slab sa mound ng pitcher kung saan dapat magsimula at magkumpleto ang pitcher ng legal na delivery. Ang hindi tamang pag-alis o pagkaladkad palabas ng rubber ay nagreresulta sa illegal na pitch.
