Federer, Serena Lead Wimbledon Quarters Odds

It's quarterfinal time at Wimbledon, and that means that eight men and eight women are in the running to win world tennis's most lucrative Grand Slam tournament.

Five of the top six seeds remain in the running in the men's tournament, which means the top prize is well and truly up for grabs.

Number one seed and six-time Wimbledon winner Roger Federer remains the steady favorite, 5/4 at William Hill, ahead of Rafael Nadal, 3/1, local hero Any Murray, 4/1, Robin Soderling, 8/1, and Novak Djokovic, 25/1. Rounding out the betting are Tomas Berdych, 25/1, Jo-Wilfried Tsonga, 33/1, and the only unseeded player remaining, Taiwan's Yen Hsun-Lu, 66/1.

The two top seeds in the ladies' singles - Serena and Venus Williams - remain in the tournament, but it is slim pickings after that.

Serena is an odds-on 4/5 favorite for the tournament, followed by Venus, 9/4, and eight seed and two-time Grand Slam winner Kim Clijsters, 5/1. All other contenders range from 20/1 to 125/1.

Meanwhile more than £11 was wagered at British bookmakers on the result of the record-breaking first round match between 23rd seeded American John Isner and unseeded Frenchman Nicolas Mahut.

The match which lasted more than 11 hours and was played over three days, finished 70-68 to Isner in the final set.

There is more to sports and sports betting than the World Cup. There's Wimbledon on William Hill.
