Wimbledon.com's highlights from the fifth day of play at the 2013 US Open in Flushing Meadows, New York...
Match of the day
Lleyton Hewitt d. Juan Martin Del Potro 6-4, 5-7, 3-6, 7-6(2), 6-1
It couldn't be, could it? Surely Hewitt, the man who has had more operations on his foot than there are bones in the foot, could not take down the physical beast that is Juan Martin Del Potro, especially not over five sets. But that's exactly what he did. The two-time Grand Slam champion, who seems to be eternally young, played a match of poise, precision and power, passing Del Potro in astonishing fashion time and time again. "It was unbelievable atmosphere. I just kept fighting and putting it out there. You know, I kept coming at him the whole night. Felt like I was seeing the ball well. Felt like I played a good game plan for most of the night as well," Hewitt said, saying that it is moments like this that keep him playing the game.
Ekaterina Makarova d. Sabine Lisicki 6-4, 7-5
These two share the fact that they have both upset Serena Williams in the fourth round of a Grand Slam, but Makarova proved to be the giant-killer today, beating the Wimbledon finalist in straight sets. Lisicki never really got going, too many unforced errors her downfall, and a particularly poor serving performance. Makarova is through to the fourth round here for the first time, and plays Agnieszka Radwanska for a first US Open quarter-final.
A little tricky
Andy Murray's four set win over Leonardo Mayer for the chance to face Florian Mayer. Murray seemed to be cruising along before dropping the third set. But still. The title defence survives.
Lightning doesn't strike twice
There was no second upset for Laura Robson over Li Na, the fifth seed proving just a bit too good for the Brit, winning 6-2, 7-5 on Arthur Ashe Stadium. Li's winner-error count was unremarkable 23-22, but 11 aces and 78 % of points won on first serve was much more telling. Robson meanwhile had seven errors to 30 unforced errors, a tricky position to win a match from. Could 2013 be Li Na's year at Flushing Meadows? Quite possibly.
Biggest win of the day went to Tim Smycek, who battled past former American now Russian Alex Bogomolov Jr in five sets, 3-6, 7-6(6), 2-6, 6-4, 6-4 to reach his first Grand Slam third round.
Sloane Stephens won the American face-off against Jamie Hampton for the chance to reach the fourth round, Stephens outplaying Hampton to win 6-1, 6-3. Hampton later admitted she was very disappointed with how she had played and that she hadn't brought it for the big occasion.
There was heartbreak though for Rajeev Ram, who was a set away from his first-ever Grand Slam third round, only to lose 3-6 4-6 6-2 6-3 7-5 to Marcel Granollers, while Donald Young departed more meekly.
Agnieszka Radwanska, Tommy Haas, Mikhail Youzhny, Novak Djokovic, Angelique Kerber, Tomas Berdych, Florian Mayer, Ekaterina Makarova, Florian Mayer, Carla Suarez Navarro, Jelena Jankovic, Julien Benneteau, Andreas Seppi, Denis Istomin, Serena Williams, the Bryan Brothers, Colin Fleming & Jonny Marray, Dom Inglot & Treat Huey, Jamie Murray & John Peers.
Martina Hingis's long-awaited comeback to the Grand Slam court ended in a straight sets defeat to the top seeds, Roberta Vinci and Sara Errani, 6-3, 7-5. Hingis buried her head in her towel at the end. The grass is always greener.

Did-you-see of the day
Serena Williams hitting one-handed backhands during her warm-up.
Junior qualifying started today. The poor umpires had to contend with names such as Wishaya Trongcharoenchaikul from Thailand and Usue Maitana Arconada from the USA. Katharina Hobgarski was simple in comparison.

20:08It brings me no pleasure but it's time to bring the curtain down for another year. Seemed somehow appropriate to leave the last word to Roger Federer. Thanks a billion for reading. What a fortnight, what a final, fast forward to 2015 please...
20:03"I already have seven. It's not like I need another one. But it would have been awfully nice to have it. I think that's what the feeling was of the people, and I felt that... I know they love tennis. They love tennis after we're all gone."View all
