Murray has set his sights on a Grand Slam title
Andy Murray will become the first British man to reach number three in the world rankings on 11 May.
The 21-year-old Scot will overtake Novak Djokovic in the ATP World Tour standings after the Serb failed to defend his title at the Rome Masters.
Murray lost in round two but has been on a superb run since last summer and now has 11 career titles to his name.
He is next in action at the Madrid Masters from 10 May as he prepares for the French Open later this month.
He has been playing really well lately but it's still close. I can get it back.
Murray is the defending champion in Madrid, although it is a vastly different event this year as it has changed from an indoor tournament in October to an outdoor clay event in May.
Since the computerised rankings were introduced in 1973, both Tim Henman and Greg Rusedski have made it to number four in the 52-week rolling standings.
But Murray has broken new ground in a year that has seen him suffer just five defeats so far and collect titles in Doha, Rotterdam and at the prestigious Miami Masters 1000.
He reached his first Grand Slam final at the US Open last September, losing to Roger Federer, and landing one of the game's four major prizes remains his primary target.
"Andy will deserve it," world number two Federer told BBC Radio 5 Live earlier this week when asked about Murray's possible move to number three.
"He didn't win the big ones but he was very, very solid in Masters Series play and I think if he becomes number three in the world everybody will agree that he absolutely deserves it."
Asked about losing third spot to Murray following his defeat by Rafael Nadal in Rome, Djokovic said: "It's very close. I'm defending a lot of points, so it's not strange that it happened.
"He has been playing really well lately but it's still close. I can get it back. It's really up and down."
