Technical Details

  • Variable Type: Discrete Metric
  • Data Type: Boolean
  • Units: True/False
  • Column Name: getting_out_in_front
  • Measurement: Trunk forward flexion angle at foot contact
  • Threshold: >20° of forward flexion at foot contact

​
Description

Getting out in front is a binary indicator that flags early trunk forward rotation during the pitch. It occurs when the trunk forward flexion angle is greater than 20 degrees at foot contact.

​
Use Cases

  • Trunk position assessment

​
Corrective Drills

​
1. Tall Posting Drill

At the moment of foot contact, actively cue “stay tall” — the trunk should be upright (or slightly tilted back) rather than already flexing forward over the lead leg. Practice this in slow-motion reps by holding the “foot contact” position for 2–3 seconds, confirming trunk is vertical before continuing the throw. Perform 20 reps.

​
2. Wall Brace Drill

Stand with the back to a wall about 1–2 feet away. Perform the delivery and monitor whether the upper back touches the wall at foot contact (which would confirm the trunk is leaning back, not forward). If the back doesn’t contact the wall, the pitcher is getting out front too early. Use as a diagnostic and corrective tool for 15 reps.

​
3. Front-Side Brace Throw

Throw at 60–70% effort while actively trying to “brace” the front leg and keep the chest pointing upward at foot contact, only allowing forward trunk tilt after the ball is released. This teaches the pitcher to separate the timing of foot contact (still upright) from trunk flexion (post-contact). Perform 3 sets of 8–10 reps into a net.
