Roland Garos

The French Open is the only major tennis event held on clay, and takes place at the end of May each year. Nadal has won the title an amazing 7 out of the last 8 years, and his dominance on clay looks to continue in 2013 as he is currently odds-on favourite with most online betting firms.

The women's event at the French Open looks set to be a lot more competitive for 2013, with Serena Williams, Victoria Azarenka, and Maria Sharipova all popular in the early betting.
