Roger Federer is two victories away from becoming world number two as he takes on Janko Tipsarevic in the Madrid Masters semi-finals.
Federer's path to overtaking Rafael Nadal in the world rankings looks a lot clearer after Novak Djokovic's shock quarter-final defeat to Tipsarevic on Friday. The upset was not completely unexpected as Djokovic has been complaining about the courts all week and has been far from his best. However Tipsarevic played out of his skin to force the win, smashing 30 winners past a frustrated Djokovic.
The Serb is seeking to reach his first Masters 1000 final. It's been a stunning twelve months for him, he's gone from being one of the biggest underachievers in the game to a man who's maximised his talent and has established himself at the top table.
However his path is blocked by Federer who's played some terrific tennis in the past two rounds. The Swiss is a lot lighter around the court than someone like Djokovic and he has had few difficulties with movement, playing some superb attacking tennis to see off Richard Gasquet and David Ferrer.
Ferrer had never previously beaten Federer on tour and he never even achieved a break point opportunity as the Swiss eased to a 6-4, 6-4 win.
Tipsarevic's chances do not look too great as he has lost all four of his career matches to Federer. The Swiss beat him 6-1, 6-4, 6-3 at the French Open last year and will be favourite to prevail in straight sets.
