​
Description

Late rise is a binary indicator that flags delayed wrist elevation (flip up) during the pitch. It occurs when the wrist is positioned below the elbow at foot contact.

​
Use Cases

  • Timing assessment
  • Arm position evaluation

Corrective Drills

​
1. Early Arm Circle Drill

Break the hands early (before the peak of the knee raise) and complete a full, deliberate arm circle so the throwing hand is already working upward — wrist above the elbow — by the time the foot contacts the ground. Throw at 50% effort into a net for 20 repetitions, focusing entirely on early wrist elevation. Search YouTube: baseball pitching early arm circle drill wrist elevation late rise

​
2. Glove-Hand Mirror Drill

Focus on the glove hand and throwing hand staying synchronized: as the glove arm rises toward the target, the throwing hand should “flip up” simultaneously so both wrists are rising at the same rate. This symmetric timing cue helps break the habit of keeping the throwing wrist low late into the stride. Perform 15–20 walk-through reps.

3. High-Arm Towel Drill

Use a towel drill where the specific cue is to have the towel/throwing hand at ear level (wrist above elbow) before the front foot lands. A coach or video confirms the wrist position at the foot-contact frame. Perform 3 sets of 10 reps with a deliberate pause at foot contact in slow motion before building to full speed.
