Beginner

Prolongé

Also known as: finition, finition de l’élan

Definition

Le prolongé est la continuation de l’élan après le contact, où le bâton complète son arc, les bras s’étendent complètement et le corps termine dans une position équilibrée, le poids vers l’avant.

Techniquement, la balle a déjà quitté le bâton au moment du prolongé, il ne change donc pas directement le vol de la balle — mais une mauvaise finition est toujours la preuve d’un mauvais élan. Un prolongé coupé (les bras se replient, le corps pivote vers l’extérieur) indique que le frappeur a décéléré avant le contact, réduisant la vitesse de bâton au moment où elle compte le plus. Un prolongé complet et haut montre que le frappeur a maintenu son accélération à travers et au-delà de la balle, ce qui produit la vitesse de sortie maximale et l’efficacité du baril.

Beginner tip

Aim to finish with both hands above your lead shoulder and your belt buckle facing the pitcher. This means if you can check both at your finish position, your follow-through is complete.

Advanced note

Practice swings where you deliberately hold your finish for two full seconds after contact to train muscle memory for a complete follow-through rather than an instinctive deceleration after the ball leaves the bat.

Example

Le frappeur termine avec le bâton au-dessus de l’épaule avant, le nombril face au lanceur et le poids sur le pied avant — tous les indicateurs d’un élan sans retenue, à pleine vitesse.

How it shows up on video

A complete follow-through on video shows the bat finishing high on the lead side of the body (above the lead shoulder) with the trail shoulder rotating fully toward the pitcher and the hips completing their turn past the ball. An abbreviated follow-through shows the bat stopping at or just past contact, often indicating the hitter was decelerating into the ball rather than swinging through it. The trail foot position at the finish — balanced on the toe with the heel lifted — confirms the hip rotation was complete.

Common mistakes

  • Stopping the swing at contact to try to control ball direction. This actually reduces bat speed through the contact zone by beginning deceleration before hitting the ball
  • Rolling the top hand over too early, causing the follow-through to wrap around the lead side rather than driving through and above the lead shoulder
  • Not completing hip rotation through the follow-through, leaving the hips square to the pitcher rather than finishing past them, which stalls the kinetic chain mid-swing
  • Thinking the follow-through does not affect the ball. This is because contact is already made. This means it does. This is. This is because the follow-through reflects whether the swing was accelerating or decelerating at the moment of contact

SwingVantage analyzes the follow-through completion from side-on and front-on video, measuring bat finish height and trail-shoulder rotation to identify abbreviated or top-hand-rollover follow-through patterns.
