In the men's draw, Roger Federer was left waiting until almost midnight to start his US Open fourth round match but made up for the delay with a brutal 6-1, 6-2, 6-0 dismantling of Argentine Juan Monaco to reach the quarter-finals.

The match lasted an hour and 22 minutes the win marks the Swiss master's 30th successive trip to the quarter-finals of a grand slam, dating back to the 2004 French Open. The 16-time major champion advances to a mouth-watering clash against 11th seeded Frenchman Jo-Wilfried Tsonga. A rematch from Wimbledon that Federer lost.
