Topspin Serve

To serve with topspin, toss the ball almost directly overhead. The racket brushes upward behind the ball from 7:00 in the direction of 1:00. Contact is farther back than in a normal serving motion. Topspin serves should clear the net 2 or 3 feet (60-90 cm) higher than the flat serve. To achieve a topspin effect, change your grip from a Continental to an Eastern backhand.
Slice and topspin work well on second serves. The racket speed is the same or even faster than on first serves, but the angle at which the racket contacts the ball imparts spin, creating a greater margin of error and a safer service attempt.
