Serve Faster: Wrist Lag, Coil, Semi-Western, Eyes Down, Legs, Depth, Topspin

Summary

Shea Underwood stacks serve-speed cues: wrist lag then snap, a deliberate backswing that coils the hips, semi-western (heel pad bevel 3 / index knuckle bevel 4), eyes down through contact, torso upright with bent knees, a step behind the baseline for margin, and low-to-high brush for topspin.

Key takeaways

• Lag the wrist and snap at contact for paddle-head speed
• Coil with a controlled backswing; use the legs
• Topspin + depth behind the baseline lets you hit harder in

Action items

• Film 10 serves focusing only on wrist lag
• Move one step behind the baseline and compare in-count at the same swing speed
