In tennis, each player uses a tennis racket to strike a ball over a net and into the opponent's court. The object of the game is to play the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.

The Tennis competition at Baku 2017 will take place at the Baku Tennis Academy, a venue which has previously hosted a number of international events. Tennis originated in Birmingham, England, in the late 19th century.

Facts and figures:
