Second Serve Spin

Because a double fault surrenders the point outright, the follow-up is played on a different priority: consistency over raw pace. Adding topspin lets the server hit with a higher net clearance and still have the ball dip down into the box. Topspin pulls the ball downward in flight. It usually comes from brushing up and across the ball with a more vertical racquet path and a slightly later contact point. The ball can be struck with real racquet-head speed and still land safely inside the line. A flat attempt has almost no such tolerance.

Topspin is the most common pattern here because the ball also jumps sharply off the bounce, pushing the returner back and off balance. Reliability comes from trusting rotation to create the margin rather than decelerating. Many club players slow the racquet down instead. That cuts both spin and pace and produces a short, attackable ball. A well-struck one is hit at nearly full speed. Rotation, not caution, is what keeps it in.
