Information:  - Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court.

The player who is unable to return the ball will not gain a point, while the opposite player will.  - John Patrick McEnroe Jr. (born February 16, 1959) is an American former World No. 1 professional tennis player, often rated among the greatest players of all time in the sport, especially for his touch on the volley.
