how far can he go.
Already up to 21 in the world, beat henman in round 1 for the second time in less thatnj a week and has now inflicted upon Federer his first loss in 55 hard court matches.
I think he'll be top 10 by the end of the season.
Brilliant Murray outplays Federer
Andy Murray
Murray's confidence will be sky high after beating Federer
Andy Murray pulled off the biggest win of his career, beating Roger Federer 7-5 6-4 in the Cincinnati Masters.
The teenager became only the second player to beat Federer this year, and it was the first time the Swiss had lost before the final for 18 events.
Federer was far from his fluent best, but an inspired Murray took full advantage, breaking serve seven times.
The Scot has struggled to serve out in recent matches, but had no such trouble as he completed his straight sets win.
