I have witnessed this a LOT. It happens to EVERYONE. What the person in the story should have done is hit a HIGH VOLLEY. It is a combination of a slam and a regular volley. You will end up playing way more high volleys than slams.
1. Continental (hammer grip)
2. Stiff wrist
3. no backswing
4. TRY to hit a forehand volley
My high volley during a match. Serve and volley clean winner.
If you play doubles, this high volley will put you up on a pedestal amongst your peers. I am not joking. The ability to recognize and hit a high volley is SUPER VALUABLE because if the ball drops lower or raises higher than you thought, you only have to make a slight adjustment either way. Try to EXPECT the high volley before you expect the slam and you should cut your errors down on that shot about 30%.
