Ana vs Clijsters

Ana vs Clijsters

Ana takes on world No.3 and defending champion Kim Clijsters in the fourth round of the US Open on Sunday, after she beat Virginie Razzano 7-5, 6-0 in round three. The match will be the third between the pair and the second in a month, following their aborted meeting in Cincinnati when Ana was forced to retire because of injury.

Only three games were on the scoreboard when Ana retired last month amid distressing scenes for her supporters. She has recovered well and, despite being forced to withdraw from New Haven, Ana has swept into the last 16 without losing a set - and so has Clijsters.

The Belgian also beat Ana in Antwerp four years ago by a 6-2, 6-1 scoreline. Furthermore, the pair enjoyed an entertaining one-set exhibition match in New York earlier this year, with Ana missing a match point before losing 7-6.

"It's going to be a tough match, no doubt about it," said Ana. "But I'm really looking forward to it, because I was really disappointed that I had to stop in Cincinnati. So it's kind of a new opportunity for me.

"Kim is a great player. She hasn't lost a match here in a long time (since 2003, to be exact). So I can go out there and try to do my best. I've been playing really well. It's gonna be exciting no matter what.

"I think in some ways we have similar games. It's going to be a fun match, I think."

Ana and Clijsters are both known for their sunny dispositions, and so it's no surprise that they share a friendship. "She is such a nice person," said Ana when told that Clijsters had expressed a desire to play her in round four.

"When I was struggling, she was messaging me. She was very supportive. That's really rare and really nice to see.  In those times, you know who your friends are. She's definitely a nice girl.  We always have a nice time catching up. So it's going to be fun."

The match is scheduled to take place at 11am local time (5pm Central European Time) on Arthur Ashe stadium. Click here for live point-by-point scoring from the Billie-Jean King USTA National Tennis Center.
