Sortie - A poach in which the poacher strikes out past center to cut off a shot but withdraws to the side of the court he or she started on. (In an all-out poach, the poaching team switches.)
Placement - A shot hit to an area where the opponent cannot reach it.
No-man's land - The area between the baseline and the service line, so called because a player who is caught there finds it difficult to hit ground strokes and isn't close enough to the net to hit slams..
Service line - The line that marks the back boundary of the service courts on each side of the net.
Longer Frame - An extra long racquet has a length greater than 27 inches. Such racquets provide greater leverage and reach, but may be less maneuverable.
Power Groove System - A frame geometry where a recessed groove is incorporated into the frame cross section and spans the entire inner surface of the racquet head. The groove expands the string bed area and in effect increases the effective length of all strings within the string bed. This makes the string bed elasticity more uniform across the string bed, especially in the shoulders of the frame where intersecting strings are the shortest, to expand the Power Zone or Sweetspot of the racquet.
Match - A tennis contest made up of sets, as a set is made up of games. In major competition, a men's match is made up of five sets and the winner is the player who first wins three sets. Women usually play best-of-three matches.
Center of Percussion - One of the three sweet spots on your racquet, this is the point on your string bed where the ball will produce minimal initial shock to your hand.
Ceramic - Materials are used in some composite frames, along with graphite. They provide stiffness, but their weight and brittleness have limited their use.
Frame - The oval portion of the racket that contains the strings; an unstrung racket.
Heavy shot - the opposite of a floater. It's a shot traveling faster than it seems to have been hit, because it's a "sweet" shot produced by a slow, effortless swing.
Miss-hit - a weird shot produced by off-center contact with the ball. Miss-hits are often frame-shots.
Penalty point -.
Retrieve - To reach and return a shot that's difficult to get to.
Tiebreaker - A method of determining the winner of a set that's tied. The most commonly used is the 13-point tiebreaker, which is won by the player who first wins 7 points, provided that the margin of victory is at least 2 points. This is sometimes called a "lingering death" tiebreaker, on contrast to the sudden death tiebreaker.
