Andy Murray will target Olympic Games and US Open glory after clinching the biggest title of his career.

The British number one climbed to a personal high of sixth in the world rankings after beating Novak Djokovic in two tie-breaks in the final of the Cincinnati Masters Series event last night.

Murray will be Great Britain's representative in the singles tournament at the Olympics in Beijing, where the likes of Djokovic, Roger Federer and Rafael Nadal will also be competing for medals. He will also team up with his brother, Jamie, in the doubles event.

Djokovic had beaten Nadal, the Wimbledon champion and world No 1, in the Cincinnati semi-finals, but for the second time in a fortnight Murray got the better of his fellow 21-year-old.

"I've beaten Novak twice in the last couple of weeks now and he's obviously played great all week," Murray said. "It gives me a lot of confidence going into the Olympics and US Open."

The Scot is determined to improve on his record at the highest level, having reached his first grand slam quarter-final at Wimbledon. Murray believes the sixth tournament victory of his career is a sign he is ready to improve on that record, with the US Open following the upcoming Games.

"It's huge. Masters Series titles are so huge to win," Murray said. "I played five matches in five days in this sort of heat against guys like Novak, [Carlos] Moya and [Ivo] Karlovic. They're all tough matches. It's a great test physically and all the work off the court is paying off.

"I've got to try to stay grounded and get back to the gym and practice court, and make sure I don't get too ahead of myself because I've only made one quarter-final at a slam and never gone deeper than that, and that's got to be my next goal."
