LONDON: The Grand Slam Board on Tuesday announced a number of changes that will come into play at the four tennis majors in the coming years.
The announcements are the outcome of decisions arrived at after two days of meetings here last week:
— A player who retires from a first-round match or "performs below professional standards" could face a fine as high as the entire prize money due a loser in that round.
— A 25-second serve clock will be tried out at the Australian Open in January, but like at this year's US Open, only in the qualifying rounds.
