With the exception of Wimbledon and the US Open, the renowned Canadian Open -- now known as the Rogers Cup -- is the oldest ongoing tennis tournament. The Rogers Cup men this year will play at the Uniprix Stadium in Montreal, Canada. The Women's group will play at the Rexall Centre in Toronto, Ontario. As an ATP World Tour Masters 1000 and WTA Premier 5 Event. That means all the cool players will be there. Get live tennis odds at Bookmaker sportsbook -- the premier site to bet on tennis!

Online Tennis Betting: On the men's side, every single player in the top 30 in the ATP World Rankings is scheduled to participate. It gets better on the women's side: so far, the top 41 players in the world are currently in the tournament draw. That includes the Williams sisters, Maria Sharapova and No. 1 ranked Caroline Wozniacki.

Andy Murray will be back to defend his title after a 7-5, 7-5 victory over Roger Federer last year in Toronto. He also beat Rafael Nadal -- then ranked No. 1 -- in the same tournament. He'll look to recapture the magic this year.

The current world No. 1, Novak Djokovic, is having a scorching hot year and is the only other player besides Nadal and Federer to achieve the top ranking since February of 2004. He won as many as 41 matches in a row until he lost to Federer in the Roland Garros semifinals.

Caroline Wozniacki and Vera Zvonoreva were the women's finalists last year, with Wozniacki taking the Cup after a thrilling finale. She'll be back to defend her title against this year, as will Zvonareva to finish what she started last year.

Kim Clijsters, the WTA No. 2 player is also participating and a threat through all rounds. Chinese player Li Na, who's having a stellar season, will test her luck in the friendly Canadian borders, and her well-rounded play is a good bet throughout the tourney.
