Federer is through to the last eight of the US Open but will he face Tomas Berdych or Richard Gasquet?


Federer 7-6(0) 7-6(6) 7-5 Isner. Game, set and match! Once again Isner finds himself triple break point down although this time they are also match points to Federer.

He saves the first with a forehand volley winner while Federer goes just long with a forehand down the centre of the court on the second. Federer nets a backhand on the third to a scream of "yes" from Isner, who then goes on to hold. The American has not dropped a service game since 2013 in the US Open singles.


Federer 7-6(0) 7-6(6) 4-3 Isner. This match has been going two hours and 20 minutes and both players have had exactly five opportunities to break. But we've yet to see a break of serve and Federer posts another service hold, without drama, to sneak ahead once again.

Federer 7-6(0) 7-6(6) Isner. Set. Isner must be wondering what he has to do. The American has a 5-3 lead and is potentially just two points away from levelling up the match. But Federer storms back into contention with the next three points before netting a forehand drive volley to allow Isner to level at 6-6 for the second change of ends. A blistering forehand return of serve winner down the line followed by a backhand winner down the opposite line from Federer wrap up the set, however, and the world number two has one foot in the quarter-finals now.


Federer 7-6(0) 6-6 Isner. Federer throws in a poorer service game once again to give Isner a small look at finishing this set without the breaker. But from 30-all, Federer again slams the door shut and goes on to hold with a forehand winner and force the second set breaker.

He saves the first with a big serve that Isner cannot return and the second with an ace but another big serve denies Isner on the third break point. Federer also faces a fourth but this time a trip into the net and a forehand volley winner buried into the open court saves it before he too goes on to hold.

Federer 7-6(0) Isner. Set. Wow! Federer races through the breaker with a couple of aces through in for good measure.

Another backhand astray and Federer has the first set under his belt.


Federer 6-6 Isner. Shocking to no-one this set will conclude with a tie-break as Isner book-ends his game with a couple of service winners, withstanding a great bit of pressure from Federer in the middle. Isner holds to 30 to take this opening set into the breaker.


Federer 6-5 Isner. Federer's only first serve in of the game comes on the final point when he aces Isner to hold and move ahead once more. And yet, he can miss four consecutive first serves and somehow still hold with ace, such is the quality of his follow-up shot.


Federer 5-5 Isner. Very confident from Isner to keep this opening set alive with a service hold to 15. One thing is for sure, even if this match goes to five sets, it's not going to be a long match - both players moving through games so quickly.

Federer earns himself a third chance at the break with a trademark backhand winner down the line. But again Isner saves it, before going on to hold with an ace and a forehand volley winner.

Federer 2-2 Isner. An unreturnable serve and ace quickly follow one another as Isner eases through a hold to 30 - backhand winner helping Federer with his second point of the game.


Federer 2-1 Isner. Federer goes for the barn-storming smash winner across court only to pull his ball down into the bottom of the net. He could have let the ball bounce first and, in fact, it could have been pretty close to being out, but Federer goes for the big shot only to fail. Still it's only a temporary blip as he holds on the next point to hold once again.


Federer 1-1 Isner. Big serve, big forehand. That's the way of things with Isner and that's how he eases through a service hold for the loss of just the one point, sealing the game with an inside out forehand winner that lands right on the line across court.


Federer 1-0 Isner. The last meeting between these two came back at the London Olympics in 2012 when Federer won in straight sets, and that is exactly the way he has started today with a love service hold to get his side of the scoreboard ticking over.


Federer leads the head-to-heads by four wins to one over Isner, the American's one victory coming on a clay court in the Davis Cup back in 2012.
