Jamie Murray becomes first British man ranked no.1 in world
Jamie Murray has become the first British man to be ranked number one in the world, after rising to the top of the doubles rankings.
Murray will rise to the summit when the updated list is released on Monday after Marcelo Melo lost in the second round of the Miami Open.
Melo and partner Ivan Dodig lost 7-6 6-4 to Treat Huey and Max Mirnyi, causing Melo to drop below Murray's 7,505 ranking points.
Murray is the first Briton of either gender to top the rankings since Virginia Wade in 1973, getting the better of his brother Andy who is the singles number two.
Jamie Murray won his first Grand Slam title at the Australian Open in January, and played a key role in Britain's Davis Cup success last season.
