Wimbledon.com's highlights from the sixth day of play at the 2013 US Open in Flushing Meadows, New York...
Philipp Kohlscreiber d. John Isner 6-4, 3-6, 7-5, 7-6(5)
For the second year in a row, German No.1 Kohlschreiber took down John Isner at the US Open, playing crisply and freely on Louis Armstrong to send America's top-ranked player packing. He meets Rafael Nadal in the fourth round, his ninth Grand Slam fourth round. He's made it to the quarters just once, at Wimbledon in 2012.
Camila Giorgi d. Caroline Wozniacki 4-6, 6-4, 6-2
Playing in prime time, the young Italian gave the performance of her life to upset the former finalist and sixth seed. Aged just 21, a qualifier, and the world No.136, Giorgi dealt Wozniacki her second straight Slam loss to a player ranked outside the top 100. Her father spent the second two sets sitting on the steps instead of in the box because she began to play well while he was sat there, and he was too superstitious to move.
Victoria Azarenka  d. Alize Cornet  6-7(2), 6-3, 6-2
Don't make Vika angry. That should be any contender's motto, and, unfortunately for Alize Cornet, the world No.2 got extremely fired up midway through their match as an overrule went the wrong way for her. Cornet was painting the lines where Azarenka was missing them as she snatched the first set with an impeccably played tie-break. But the second seed fought right back, one break giving her the second set, two breaks the third.
Milos Raonic  d. Feliciano Lopez  6-7(4), 6-4, 6-3, 6-4
The ATP will have been watching nervously as the last man-of-the-future standing dropped the opening set of his match to the ageing Lopez. But Raonic gathered himself to thunder through in four.
David Ferrer  d. Mikhail Kukushkin 6-4, 6-3, 4-6, 6-4
The fourth seed seemed less than amused when the curly-haired Kazkah won the third set of their match and ground him down eventually.
Ana Ivanovic  d. Christina McHale 4-6, 7-5, 6-4
McHale, enjoying a resurgence into relevancy in front of the American crowds, had Ivanovic very much on the ropes as she pinched the first set of their third round, and looked in danger of making it a career-making win when she went a break up in the second too. But Ivanovic fought right back and is thus through to her third major fourth round of the year after a gutsy comeback. Her performance was error-strewn, 51 of them, but winner-strewn too, 45. She'll need to tighten up for her next match though, against Victoria Azarenka.
Credit to Daniela Hantuchova, too, who saved four match points to fend off American Julie Glushko. Poor Glushko lead 5-1 in the third for the chance to face fellow American Alison Riske in the fourth round.
First there was Simona Halep. The Romanian, the 21st seed, delivered a 6-1, 6-0 thrashing of 14th seed Maria Kirilenko in 51 minutes. Halep was helped by Kirilenko's 24 unforced errors, and very poor serving percentages (41% of first serve points, 26% of second serve points), but still.
Then there was Alison Riske, who pulled off an astonishing 6-3, 6-0 win over Petra Kvitova, the 7th seed. Riske's first set was flawless - just three unforced errors, although even Kvitova was fairly restrained with 13. It later emerged that Kvitova is suffering from a virus and a high fever, and was lucky to even be playing at all. Still, it was a first top 10 win for Riske, and her first Grand Slam fourth round as a result. Before this tournament, she had played in just two main draw Grand Slam matches on hard courts and lost both of them. Now she's won three matches in a row.
And then, in a match of the older goldies, Flavia Pennetta continued her hot streak, felling 27th seed and former champ Svetlana Kuznetsova 7-5, 6-1.
Finally, the Dan Evans US Open experience came to an end at the hands of Tommy Robredo in four sets, 7-6(6), 6-1, 4-6, 7-5, Evans taking it to the elderly Spaniard as best he could, and coming within a point of taking it to a fifth set. It's not the first time Robredo has spoiled the British party - he beat Andy Murray when he and Laura Robson were on the verge of clinching the Hopman Cup diamonds.

The doubles team of Daniel Brands and Philipp Oswald, who ran in to take a between-sets bathroom break in the media centre bathroom. It didn't help them. They lost.

20:24...But boy, it was a barrow-load of fun. I hope you enjoyed it even half as much as we did. Thank you for all your messages throughout, you've been the glue holding us together as the edges frayed amid the madness. Now if you'll excuse me, it's time for us Brits to raise a toast to Andy Murray and Fred Perry. British sporting legends both.
20:19It was the wackiest of Wimbledons with the most unlikely of headline-makers: Sergiy Stakhovsky, Steve Darcis, Michelle Larcher de Brito, Kimiko-Date Krumm, Jerzy Janowicz, Sabine Lisicki, Marion Bartoli...View all
