US Open 2012: Sharapova and Djokovic in Action on Day Seven, Where to Watch Live

Tougher competition awaits top tennis players Novak Djokovic and Maria Sharapova on the seventh day of the US Open 2012.

Day Six Round-up

Men's Singles: Olympic champion and third seed Andy Murray of Great Britain goes through after seeing off Spain's Feliciano Lopez, the 30th seed. The Scot won 7-6, 7-6, 4-6, 7-6 in the Louis Armstrong Stadium.

Also through to the next round are 12th seed Marin Cilic of Croatia, who beat 17th seed Kei Nishikori of Japan in four sets, and world number one Roger Federer, who thumped Fernando Verdasco of Spain (the 25th seed) 6-3, 6-4, 6-4 at the Arthur Ashe Stadium. Slovakia's Martin Klizan upset 32nd seed Jeremy Chardy of France in straight sets, winning 6-4, 6-4, 6-4.

It was not, however, a good day for the American contingent at their home event: local boys Jack Sock and James Blake were defeated. Unseeded Sock's 6(-7, 7-6, 6-7, 1-6 defeat to 11th seed Nicolas Almagro of Spain may not have been a surprise, but Blake's straight set 3-6, 0-6, 6-7 loss to 15th seed Milos Raonic of Canada was a mild shock. Fortunately for the home crowd, 23rd seed Mardy Fish kept their hopes alive, with a 6-1, 5-7, 7-6, 6-3 win over 16th seed Gilles Simon of France.

Women's Singles: In the women's half of the draw, 12th seed Ana Ivanovic of Serbia registered a 6-7(4), 6-4, 6-2 win against American teenager Sloane Stephens to progress to the next round, while Olympic gold medallist and fourth seed Serena Williams continued her all-conquering Wimbledon and grass court form, sweeping aside Russian Ekaterina Makarova 6-4, 6-0 to the delight of the home crowd. Meanwhile, 10th seed Sara Errani of Italy also progressed in style, crushing Russia's Olga Puchkova 6-1, 6-1.

Here are the other significant results:

• Angelique Kerber (GER)[6] beat Olga Govortsova (BLR) 6-1, 6-2
• Maria Kirilenko (RUS)[14] lost to Andrea Hlavackova (CZE) 5-7, 6-4, 6-4
• Tsvetana Pironkova (BLR) beat Silvia Soler Espinosa (ESP) 6-1, 6-7, 6-3
• Agnieszka Radwanska (POL)[2] beat Jelena Jankovic (SRB)[20] 6-3, 7-5
• Roberta Vinci (ITA)[20] beat Dominika Cibulkova (SLO)[13] 6-2, 7-5

Day Seven Matches (All Times BST):

The day's action starts at 4pm on Arthur Ashe, where second seed and defending champion Novak Djokovic will face 23rd seed Julien Benneteau of France. That will be followed by home crowd favourite Andy Roddick[20] facing Fabio Fognini of Italy and then by women's top seed Victoria Azarenka of Belarus playing Anna Tatishvili of Georgia, in a fourth round singles match. The two men's encounters are both third round affairs.

The evening session at Arthur Ashe will see third seed Maria Sharapova take on 19th seed Nadia Petrova in a battle of the Russians, with a place in the quarter final at stake. That game will start at midnight on 2 September in the UK.

Over on the Louis Armstrong court, Australian Lleyton Hewitt takes on Spain's David Ferrer, the seventh seed, in a third round match that is scheduled to start at 4pm. The highlight of matches on Louis Armstrong will certainly be British teenager Laura Robson's fourth round clash with seventh seed and defending champion Samantha Stosur of Australia; the match is the last of the day on Louis Armstrong. Robson has already beaten former champion and former world number one Kim Clijsters of Belgium and China's Li Na, the 2011 French Open champion.

On the Grandstand court, Argentines Juan Martin Del Potro [7] and Leonardo Mayer will face each other in a third round match scheduled for 5.30pm at the earliest. That will be followed by Richard Gasquet of France, the 13th seed, taking on the US' Steve Johnson and the 2011 women's singles Wimbledon champion, Petra Kvitova, seeded five here, taking on Marion Bartoli [11] of France, in a fourth round match.
