Points to look for:
- The player has finished turning his waist and shoulders to the left, since the power of the stroke comes mainly from the arm and wrist.
- Since the serve is a backspin serve, the player has brought his bat down to a point well below the expected top of the ball's bounce.
- The bat has been kept inside the left knee, in order to maintain better balance throughout the stroke.
- The wrist still has not cocked to any degree.
- The player is watching the ball closely.
