Bet Live: US Open Day Four

The US Open heads into day four today, with Serena Williams, Roger Federer and Rafael Nadal among those who will appear on the Arthur Ashe Stadium main court throughout proceedings. Center Court opens with Sara Errani (4) v. fellow Italian Flavia Pennetta at 11am local time (4pm UK time).

In one of the most interesting men's singles matches, Australian Bernard Tomic will be looking to extract Ashes revenge for his country against fellow young gun Dan Evans of Britain. Evans shocked 11 th seed Kei Nishikori in the first round, while Tomic also has some big scalps to his name.

In the women's singles, 7 th seeded Czech Petra Kvitova will be looking to return to form in her match against unseeded Serb Bojana Jovanovski. Kvitova is considered one of the few women capable of defeating Williams or Victoria Azerenka on her day, so her success will keep the title race interesting.

According to William Hill Sports, there are only five main contenders for the men's championship: Nadal 6/4, Novak Djokovic 15/8, Andy Murray 4/1, Juan Martin del Potro and Roger Federer 12/1. Likewise in the women's, where it's Serena 8/11, Azarenka 11/4, followed by Agnieszka Radwanska and Na Li at 16/1.

Hill is offering pre-game betting on every match being played at Flushing Meadows over the next two weeks, whether a contest of heavyweights or a match on an outside court between unseeded hopefuls.
