San Jose to Debut Serve Clock

July 11, 2018 02:36 PM

SAN JOSÉ, CA (July 11, 2018) – The Mubadala Silicon Valley Classic along with the USTA and WTA announced today that the San Jose event will be implementing new in-match innovations, including the use of a warm-up clock and serve clock.

The Mubadala Silicon Valley Classic will be the first US Open Series event, and the first WTA Premier event, to implement these rules changes. These innovations will continue throughout the summer at other US Open Series events, concluding with the US Open.

These rule changes were a result of collaboration between the tournaments, the USTA, ATP and WTA tours, and are aimed at increasing the pace of play and ensuring a consistent set of enforcement standards.

“We are really looking forward to implementing the serve clock at the Mubadala Silicon Valley Classic this summer,” said Tournament Director Vickie Gunnarsson. “I think it will certainly improve the fan experience at the event. Not only will it speed up the pace of play, it will bring even more excitement and drama to the matches.”

The first initiative is the warm-up clock. A one-minute clock will begin when the second player or doubles team entering the court arrives at their chair(s).  If at the end of that one minute, a player is not at the net, they will be notified by the Chair Umpire and subject to a post-match fine. This will not be a time violation.

A five-minute time clock will then start following the coin-toss and begin the warm-up period.  During this time, the Chair Umpire will make announcements informing the players of the 3-minute, 2-minute, 1-minute, 30-second and end-of-warm-up marks.  Following the conclusion on the five-minute warm-up period, a one-minute countdown will commence.  At the end of this one-minute countdown, a player must be ready to play. If a player is not ready to play, the Chair Umpire will announce a “Start of Match Violation” and the player will be subject to a post-match fine. This will not be a time violation.

The second initiative is the serve clock. The server will be given up to 25 seconds to serve.  This will be enforced in two ways. 

Following a point during a game, the score will be entered and the Chair Umpire will announce the score. At that time the 25-second clock will be started.  If the player has not started the service motion at the completion of the 25-second countdown, the Chair Umpire will issue a time violation.

After even-numbered games, the Chair Umpire will start the clock when the balls are all in place on the server’s end of the court.  If the player has not started the service motion at the completion of the 25-second countdown, the Chair Umpire will issue a time violation.

The receiver is responsible for playing to the server’s reasonable pace. The Chair Umpire will have the ability and discretion to pause the clock or reset the clock to 25 seconds if necessary.

The Mubadala Silicon Valley Classic will take place July 30-August 5, 2018 at San José State University. Tickets are on sale now at
