The 30-year-old Swiss holder of 16 Grand Slam titles will play on Sunday the winner between 2008 titlist Jo-Wilfried Tsonga of France and American giant John Isner.

　　A break of serve in the first game of each set was all the former world No. 1 needed to see off the challenge of Berdych who beat second seed Andy Murray in a marathon quarterfinal on Friday.

　　Federer won the 800th match of his career on Friday when he defeated Juan Monaco in the quarterfinals.

　　Federer made a storming start against a player who had given him problems in the past. He immediately had the big Czech on the defensive and clinched a first break of serve when a rasping cross- court forehand forced an error.

　　The third seed powered through his own serve and had a break point to go 3-0 up in the next game before Berdych finally started to find his range.

　　Federer though was comfortable on his own serve and took the first set 6-4.

　　Berdych stumbled again at the start of the second set handing Federer two break points by netting an easy-looking overhead smash and he then netted a routine forehand from the baseline.

　　Federer, who won just his second tournament of the year last week in his hometown of Basel, smoothly moved 2-0 up and he never looked like being caught from there on in.

　　A win on Sunday would be just the second time that Federer has lifted a title in Paris with his only triumph at Roland Garros in the French Open coming in 2009 when he beat Sweden's Robin Soderling in the final.
