FIVE-TIME champion, Roger Federer produced a stunning display to beat fifth seed, Robin Soderling and set up a semi final clash with Novak Djokovic at the on-going US Open.

The Swiss, 29, came through 6-4, 6-4, 7-5 in the night session on Arthur Ashe Stadium as both men defied windy conditions in a high-quality match.

"It was tough conditions to play in," Federer admitted afterwards.

He goes on to face Novak Djokovic after the Serbian earlier beat Gael Monfils 7-6 (7-2), 6-1, 6-2.

The second and fifth seeds came out onto Arthur Ashe Stadium to face the same gale force winds that had disrupted the day's earlier matches, but they produced a quality of play that belied the conditions.

Federer was expected to face his first serious test of the tournament against the man who beat him at the French Open, and it was Soderling who had the early chances.

Three break points came and went in game two and another in game six, each time Federer finding a first serve when it mattered, and while both players were hitting well from the baseline it was the Swiss who was making the winners.

That proved decisive in game seven when the 16-time Grand Slam champion earned his first break point and duly converted with an absolutely magical forehand drop shot.

With his serve working at its fluent best, Federer quickly closed out the set and moved clear early in the second when Soderling cracked under the pressure and double-faulted at break point in game three.
