6.35pmJust when you thought Murray had done with Mayer's in this tournament, up pops another one. There isn't any relation though. This Mayer is an experienced player from Germany, and he comes into this match in decent form.
6.37pmMurray didn't look overly impressive during his second round encounter with Leonardo Mayer, but it's a match that will hopefully do him some good. He hasn't successfully fought himself through a match since Wimbledon, and if he gets through today, he is sure to have to fight in the later rounds.
6.41pmThe two players have just made their way onto the Arthur Ashe Stadium court, so that should mean that we will be starting at around 6.50pm.
6.44pmSo then, what do we know about Florian Mayer? The 29-year-old German is ranked number 47 in the world rankings and he has recorded two impressive victories over Juan Monaco and Donald Young. A couple of months ago, Mayer lost to Novak Djokovic in straight sets in the opening round at Wimbledon.
6.47pmBoth Murray and Mayer have completed their warm-up. It will be Mayer to serve first.
Murray *0-1 MayerThe two players share a superb opening exchange, which Mayer wins, but Murray replies with a forehand winner. A smash takes the German to 30-15, but a net cord helps Murray back to 30-30. Murray has control of the next point but the umpire wrongly steps in and overrules a call. Murray isn't impressed, but he wins the re-played point to earn a break point, but he frames a forehand high into the stands. The umpire correctly overrules on the deuce point, but wrongly penalises Mayer. Murray wastes another break point and the German comes through what was a crazy first game.
Murray 1-1* MayerA sharp return sees Mayer move to 0-15, but he goes wide with an attempted forehand winner. The next two points are shared, but Murray ends the game strongly and levels things up at 1-1.
Murray *1-2 MayerThat was a much more convincing game from Mayer, who blasts himself to 40-0 before a fine volley at the net seals the game.
Murray 2-2* MayerMurray replies with a confident service hold of his own. A couple of errors from Mayer help him along the way, and the German does fire a backhand winner to get back to 40-15, but the Scot makes it 2-2 after 18 minutes of play.
Murray *2-3 MayerMurray forces Mayer to volley into the net for 0-15, but the world number 47 hits back with three excellent points to move to within one of the game. He has Murray on the run during the next rally, who nets to ensure that the set remains on serve.
Murray 3-3* MayerThe number three seed gets his ace count up-and-running, before Mayer steps into a weak second serve to level the game.

The Scot makes an error on the next point, but he makes it 3-3 when Mayer slices the ball into the net.

Murray 4-4* MayerMurray is having a few issues with his back. I will keep you posted. His first serve finds the mark, but a double fault cancels it out. You get the feeling that Mayer senses Murray isn't at 100%, but an unforced error and coming into the net at the wrong time contribute to him falling 40-15 down. The reigning US Open champion slips up with a drop-shot, but a forehand error from Mayer concedes the game.
Murray *4-5 MayerErrors are exchanged on the first two points, before an excellent cross-court backhand earns Mayer the advantage.

Murray 6-6 (5-1)* MayerA lengthy first rally sees Mayer slice the ball wide of the line, and Murray takes the initiative with his third ace.

The German is crumbling, but after floating a forehand long, Murray goes for too much on a return. The players reach the change of ends at 5-1 after a well-placed serve isn't returned by Mayer.
Murray 7-6 (7-2)* MayerWhere has this play been for the past 50 minutes? Murray drills a forehand winner into the corner for five set points, but Mayer hits back with a passing shot. However, he can do nothing when Murray latches onto a short serve to seal the first set.

Murray *7-6 2-0 MayerBREAK! A quick service stat for you. Murray is only finding the service box 46% of the time, which needs to improve.

Murray sends a lob long on the first, but he secures the break when Mayer sends a backhand into the net.
Murray 7-6 3-0* MayerAn immaculate top-spin forehand wrong-foots Mayer to move 15-0 ahead before a smash doubles his lead.

Murray 7-6 5-2* MayerMayer gets himself into a couple of rallies, but Murray comes out on top on both occasions, firing a winner into the corner.

Murray 7-6 6-2 1-0* MayerThe third starts with a flashy exchange that Murray wins with his trademark cross-court forehand. Mayer makes it 15-15, but a second serve has too much spin on it for the German. The 26-year-old is moving through the gears now, caressing a forehand winner on the run past Mayer before a one-two off his first serves takes the game. Marvelous stuff.

Murray 7-6 6-2 5-2* MayerMurray takes the first two points, but Mayer keeps him honest by fighting back to 30-30.

Murray 7-6 6-2 6-2* MayerBREAK AND MATCH! The US Open champion takes advantage of a net-cord to take the first point before playing an utter genius of a shot. The Scot chased down a drop-shot before dinking a reply cross-court to the other side of the court without looking. Incredible. Murray has two match points, and he wastes no time in booking his place in the last 16, with Mayer driving a shot into the net.
8.50pmThe first set was far from straightforward, but the two that followed were his best of the tournament so far. He simply outclassed the German, who after a solid display for the first hour, wilted under the barrage of Murray's power.
8.50pmMurray will face Andreas Seppi or Denis Istomin in the next round.
8.51pmThat will be all from Sports Mole for this match. Thanks for joining us. Goodbye for now.
