Distance de lancer

Definition

La distance de lancer est la distance mesurée entre le caoutchouc de lancer et le marbre. Au softball slow-pitch, elle est couramment de 50 pieds (15 m), bien que certaines ligues utilisent 46 ou 53 pieds (14 ou 16 m) selon l’âge et la division.

Une distance de lancer plus longue donne à la balle plus de temps et d’air pour compléter l’arc, ce qui facilite l’obtention d’une descente prononcée. Une distance plus courte exige un angle de relâchement plus prononcé pour atteindre la même fenêtre d’arc, ce qui réduit la marge d’erreur du lanceur. Les frappeurs des ligues à plus grande distance ont plus de temps pour lire l’arc mais doivent être plus patients ; les ligues à distance plus courte exigent une synchronisation plus rapide.

Beginner tip

Before your first game at a new distance, throw 20 warm-up pitches in particular to re-calibrate your arc feel for the new rubber location.

Advanced note

Film yourself pitching from both 46-foot and 50-foot rubbers and compare release angle and step length — those differences are your calibration targets when switching leagues.

Example

En passant d’une distance de lancer de 46 pieds (14 m) à 50 pieds (15 m), le lanceur découvre que la balle monte naturellement plus haut et a plus de temps pour retomber dans la zone.

How it shows up on video

On video, measure the rubber-to-plate distance using a known reference (base path = 65 feet in slow pitch. USSSA uses 65 or 70) and confirm it matches the stated league distance. Watch the pitcher's stride length as a proportion of the pitching distance. This means a very short stride at 50 feet often indicates poor forward momentum and arc uneven results. Reviewing total ball flight time across pitches helps batters calibrate their load timing for the specific distance.

Common mistakes

  • Pitchers not adjusting release angle when moving between 46-foot and 50-foot rubbers, causing arc-height violations at the new distance
  • Batters using the same load timing from a different-distance league without adjusting, arriving reliably early or late
  • Coaches not confirming the official pitching distance before warm-ups, leading to a mechanical surprise on the first inning pitch
  • Pitchers overcorrecting at longer distances by pushing harder rather than adjusting angle, increasing speed beyond league limits
