Good evening (or morning) tennis fans! Welcome to Sports Mole's live text commentary of Richard Gasquet vs. Roger Federer in the quarter-finals of the US Open. The weather in New York has been somewhat turbulent over the cause of the day, but the skies have calmed - for now at least - and so the show will go on, an hour earlier than originally intended.

This game has the potential to be a cracker. 12th seed Gasquet has performed well so far in the US Open, and produced a shock to upstage Tomas Berdych last time out in four sets. As for Federer - what can I say? The five-time champion has had an impressive tournament so far, and beat John Isner in straight sets last time out.

The world number two has just spoken to ESPN ahead of the match, on Gasquet: "He's playing very well, I really think it's linked to confidence and shot selection at the right times." And on himself: "The match was great against Isner, it was tough, I played well... I hope I can keep going here."

The players are on the court, and after a warm-up the action should be under way soon...

In 16 attempts, Gasquet has only beaten Federer twice - the most recent being at the Rome Masters in 2011. This is the first time that the two have met at the US Open, where the Frenchman made his best appearance two years ago, reaching the semi-finals.

One minute until the match begins. Can Federer progress as expected, or will Gasquet maintain his good 2015 form tonight?
