Maria Sharapova calls for three-set Grand Slam matches for men
Maria Sharapova says men's Grand Slam matches should echo the women's game and be played over three sets.
The Russian, 26, told BBC Sport it would not only make the men's game more appealing, but could lengthen careers.
"It would be more exciting from the beginning of the match because you know that first set is extremely important," said the four-time Grand Slam winner.
"When you are watching a three-out-of-five-set match, the first set sometimes doesn't mean too much."
Speaking in the build-up to this week's WTA Tour event in Indian Wells, Sharapova, one of only 10 women to have won each of the four Grand Slam titles, added: "Five-setters are extremely tough on the body.
"Men have expressed a lot of concern, especially to the matches that last five hours, in terms of recovery."
However, Britain's Andy Murray is totally against Sharapova's suggestion.
The reigning Wimbledon champion and world number six said Grand Slams need to be five sets to set them apart from other events.
"You spend more time in the gym putting your body through its paces to get ready for the Grand Slams, but they are the biggest events and should be the toughest test of a player physically and mentally," he said.
"I like that it's best of five sets. because I don't think you get fluke results."
Victoria Azarenka suggested at last year's WTA Championships in Istanbul that three-set matches would be "more interesting" and this must no longer be seen simply as a riposte to male players who believe women should play five sets to justify the equal prize money introduced at all the Grand Slams since 2007.
The demands of the modern viewer and the attritional nature of many of the men's hard-court matches mean this is no longer a purely hypothetical debate.
The International Tennis Federation told BBC Sport last year that it was actively considering reducing Davis Cup rubbers to the best of three sets in the early rounds of the competition.
