French Open 2012 odds: Nadal and Serena are favorites

The 2012 French Open odds may shift slightly on Friday when the official draw is released, but certainly not enough to change Rafael Nadal's status as the presumptive favorite to win his seventh title at Roland Garros. On the women's side, Serena Williams has the lowest odds, swapping places with a slumping Victoria Azarenka in recent days.

Here are the odds for the top 13 players in each draw (via William Hill):

• Four men have won the past 28 Grand Slams and three (Federer, Nadal, Djokovic) have won 27 of those 28. In the same span, 13 women have won Slams, including a different victor in every major since the 2011 Australian Open. Thus, it's little surprise that the fifth best odds on the men's side are 25/1 compared to 10/1 on the women's.

• Even at 5/6, Nadal seems like a pretty good choice. Those are the same odds he was getting last year when Djokovic had defeated him twice on clay and was undefeated headed into the tournament.

• Betting is illegal in the United States; thanks, Puritans! If it wasn't, I'd be very interested in losing some cash on Angelique Kerber at 20/1.

• Will Aga Radwanska's odds shift if she gets placed on the opposite side of the draw from her 2012 nemesis, Victoria Azarenka?

• Mona Barthel? Most of the time, when you see an out of place line like that, it's a sure sign the oddsmakers know something you don't. In this case; no.
