Good evening everyone, and welcome to LIVE coverage of the Australian Open fourth round. First up is Flavia Pennetta against Petra Kvitova on Hisense Arena.

And if you want to keep an eye on all the courts, why not try the Eurosport Player online?

And as if I need remind you, you can catch this match LIVE on British Eurosport 2. There's also Soderling v Dolgopolov deep into the fifth set on British Eurosport and Eurosport HD.

BENESOVA SO FAR: Beat Anabel Medina 6-0 6-1, Maria Kirilenko 6-3 6-1, and Anastasia Pavlyuchenkova 6-3 1-6 7-5.

ZVONAREVA SO FAR: Beat Sybille Bammer 6-2 6-1, Bojana Jovanovski 2-6 6-3 6-1, and Lucie Safarova 6-3 7-6

Zvonareva really came of age last year when she reached the final of Wimbledon and the US Open, but ultimately was beaten on both occasions. She's been playing well in the first week, too.

27-year-old Benesova has been as high as 25 in the world and is currently 59th. She's had a great tournament - her best ever performance in a Grand Slam - but she's a real underdog going into this clash.

While you wait for more women's tennis, why not take a quick look at Tramlines? Our last report from Melbourne dealt with the ever-delightful Caroline Wozniacki's spell-binding press conferences.

Next up on Hisense Arena will be Petra Kvitova's quarter-final opponent - but will it be Czech compatriot Iveta Benesova or second seed Vera Zvonareva who she faces?

Kvitova was far from perfect, but she has the more complete game. Pennetta took advantage of the errors, but when Kvitova stepped up her level, it was too much for the Italian to handle. A quarter-final against either Vera Zvonareva or Iveta Benesova awaits her!

And if you can't bear to leave the screen, fear not - there's always the Eurosport Player online - and you can keep an eye on up to three courts at once!

This match, as well as the intriguing tussle between Robin Soderling and Alexandr Dolgopolov, is LIVE on British Eurosport - Sky 410/12, Virgin Media 521 - and the coverage from Melbourne continues through the night.

KVITOVA 3-6 6-3 5-3 - The Italian grinds out the first point after getting the better of Kvitova in a lengthy rally - but back comes Kvitova with a no-nonsense service winner. Pennetta takes the next point with an overhead - or does she? Challenged by Petra - but it caught the line! Another challenge next - this time by the Italian on her forehand - just wide, and back to 30-30. Kvitova digs deep, and holds her serve. Nearly there.

KVITOVA 3-6 6-3 3-3 - Fist pump from Kvitova as she swings a forehand past Pennetta for 30-15 - and then a clenched hand from the Italian as she fires straight back. 30-30 all is dangerous for Kvitova, but she gets to game point first - and levels things up again in the decider.

KVITOVA 3-6 6-3 2-3 - Magnificent stuff from Kvitova - Pennetta finds the net trying to pass on the first point, flashes a winner down the line on the second, then hits an unanswerable return the next to bring up three break points. Flavia saves the first, then thunders a winner to save the second - and Kvitova misses her attempted winner wide by a whisker. The Italian takes the next point and screams in joy - she's done a fantastic job to save that game.
