For tennis gambling fans the 2011 season is very nearly over for the top players in the world, with just the ATP World Tour Finals starting in London on Sunday, 20th November to come. In a year when all the Grand Slams and Masters tournaments have been dominated by the top four players in the world, it is difficult to look beyond the top four for a winner in the last major event of the season. Most bookmakers have last year’s champion Roger Federer as favourite to retain his title, in spite of the fact that three of the four Grand Slams have been won by Novak Djokovic this season, but we understand that Djokovic is nursing an injury and indeed pulled out of his last event. Sports fans gambling on tennis may also be surprised to see Andy Murray as second favourite ahead of both Djokovic and Rafael Nadal with both Paddy Power and Ladbrokes. Gambling on tennis is not the most popular sports gambling activity in Ireland or the UK, but perhaps now is the time for Murray to finally make the breakthrough having just had his best run of tournament victories in his career losing just one match out of his last twenty three. If you fancy a Murray victory, Ladbrokes are offering 3/1, but if you tend to agree with the bookmakers and think Federer will retain his title Paddy Power are offering 7/4. Outside these two, Paddy Power have Djokovic at 4/1 and Nadal at a surprising 5/1, although it has not been his best season he remains number two in the world. Tennis gambling fans can of course bet on each individual match during the tournament and who will win each of the two groups, plus a variety of alternative bets on sets won or games won by every player. Gambling on tennis is not restricted to outright winners, and offers a variety of gambling opportunities for tennis fans, so keep a weather eye on how the matches are playing out and place your bets.
