Five-time champion Roger Federer produced a stunning display to beat fifth seed Robin Soderling and reach the semi-finals of the 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.
It was to the Swede's credit that he recovered the deficit immediately with a backhand arrowed down the line, but a third successive break followed when he let a 40-0 lead slip as Federer fired a forehand past him at the net.
That was enough for the world number two to take the second set, such was his dominance on serve, and a straight-sets win seemed inevitable as the third set began with neither man able to fashion a break point.
When it came, it was a surprise that Soderling was the man to get the breakthrough, but Federer missed a mid-court forehand to put the Swede 5-3 ahead and within sight of a fourth set.
Soderling's attempt to close out the third went horribly wrong, however, with three successive forehand errors giving Federer the break straight back and the Swiss reeled off four straight games to seal victory with sucessive aces after one hour 56 minutes.
