|---|---|
| Damping |
Generally refers to vibration and/or shock damping. Handle systems, such as Dunlop's ISIS, Prince's Cushion Grip and Head's ShockStop are designed to reduce frame shock and vibration before they reach the player's hand. Weight is also effective in decreasing shock and vibration. Rubber string dampers reduce string vibration only - they have no effect on frame shock or vibration (it's simple physics - a 2 gram string damper versus a 250-350 gram racquet striking a 60 gram ball...).

| Double Fault |
If the server fails to serve correctly on both 1st and 2nd serves this is called a Double Fault. The server then loses this point.
|
| Drill Flash |
Debris that falls into the frame as a result of drilling the string holes. All racquet companies attempt to remove this debris during production and most racquets are drill flash-free. However, even the smallest amount of debris can cause an irritating rattle. Some racquets feature a trap door on the butt cap to allow easy removal of drill flash. Otherwise, the strings and grommets must be removed and the drill flash shaken out through the string holes.
|
| Drive |
A powerful shot using a bit of Topspin. Common as a passing shot down the line to leave your opponent scrambling for the ball.
|
| Drop Shot |
You need to use a lot of Backspin to perform this shot. It is a more severe version of a Slice, in that the idea is to get the ball just over the net and stop almost immediately just after the net without much bounce.
