5/1 for 2013 Grand Slam Repeat

After a year which saw four different Grand Slam winners, bet365 quote 5/1 that 2013 follows suit.

Novak Djokovic won the Australian Open to start things off, Rafael Nadal followed up with his now-customary French Open win, Roger Federer returned to his best at Wimbledon before Andy Murray landed a first Grand Slam of his career at the US Open.

And Djokovic's win in the ATP World Tour Finals means he heads into the winter break as 7/4 favourite for the Australian Open with Boylesports and William Hill.

Murray has now taken over as clear second-favourite at 11/4 with Ladbrokes despite being beaten by Federer in London, with the Swiss now a general 5/1 chance.

Nadal - who missed the O2 finale with a long-standing knee injury - is as big as 7/1 in a market which predictably sees four men dominate.

However, Nadal remains favourite for the French Open at 10/11 with BetVictor and Stan James ahead of 2/1 chance Djokovic, whereas Murray and Federer can be backed at 8/1 and 14/1 respectively.

Wimbledon is seen as the most competitive of the majors with Djokovic and Murray sharing 3/1 favouritism, Nadal quoted at 4/1 and Federer somewhat surprisingly a 5/1 fourth-favourite with BetVictor.

And finally the US Open betting takes a similar shape, with 2/1 shot Djokovic narrowly heading the betting from Murray at 5/2, Nadal available at 4/1 and Federer 5s.

Murray is 5/4 to win any of the four with Sky Bet, who quote 6/4 that he ends the 2013 season as the world number one.
