The visiting team get to choose the side for receiving. In the singles sets, the visiting team serves 1 st and the home team chooses side of court for receiving. In a supertiebreaker, service is decided by a coin toss. The service is delivered in the following manner. Immediately before commencing to serve, the Server shall stand with both feet at rest behind the baseline and within the imaginary continuations of the center mark and the sideline.
Delivery is deemed complete at the moment the racket strikes the ball.
In delivering the service, the Server stands alternately behind the right and left courts, beginning from the right in every game. The ball served shall pass over the net and hit the ground within the service court that is diagonally opposite, or upon any line bounding such court, before the Receiver returns it. If the ball is erroneously served from the wrong side of the court, the resulting play stands, but service from the proper court, in accordance with the score, shall be resumed immediately after this discovery. The service is a fault if the Server misses the ball attempting to serve it, if the ball does not land in the proper service court, or if the ball served touches a permanent fixture other than the net, strap or band before it hits the ground. If the service was a fault because it was served from behind the wrong half, the server is entitled to deliver one service from the proper half of the court.
