Britain's Andy Murray has climbed to a career-high of number six in the world after winning his first Masters Series title in Cincinnati on Sunday.
Murray's victory over world number three Novak Djokovic in the final saw him rise three places in the rankings.
And the Scot, who now heads to the Beijing Olympics, feels he has proved he is capable of winning a Grand Slam.
"I think Serena books showdown with Venus ...

Swiss big-cheese Federer breezes into Hamburg final ... I have the game to win a Slam," Murray said. "My results here show I have the potential to do it."
"I've started to play more consistently in the bigger tournaments," Murray added. "And winning my first Masters event makes a big difference to my confidence.
"I have never been past the quarter-finals of a Slam before so there is still a long way to go but it is up to me to continue to work hard and produce it on court - it is just a matter of putting it all together for two weeks."
The British number one's previous best ranking was eighth, which he reached in June 2007.
Murray's next tilt at a Grand Slam will come in the US Open at the end of August and he is aiming to continue his recent improvement when he goes to Flushing Meadows.
But his form at the start of the American hard court season, which saw him reach the semi-finals of the Toronto Masters before his triumph in Cincinnati, has meant Murray has swapped places with Andy Roddick of the US, who is now ninth.
Switzerland's Roger Federer hangs on to the number one spot, but only until 18 August when he will be replaced by Spain's Rafael Nadal at the top of the rankings.
