One of the fascinating aspects of sports gambling, particularly online sports gambling is the range of different sports we can now follow. Clearly Irish sports gambling fans continue to follow horse racing and football as the top two sports gambling activities, but online sports gambling is now so accessible that almost every sporting event in the world is within our scope. Take tennis for example, not a major sport in Ireland by any measure but certainly a sport which offers a wide range of gambling opportunities all year round. As with most sports it is the major tournaments which attract both serious tennis gambling fans and those sports gambling fans who are interested in all sports, but there are also many big tournaments taking place throughout the year with all the top players in action and well worth a look for all sports gambling enthusiasts. The clay court season is now well under way and sports fans who enjoy gambling on tennis will be watching all the tournaments leading up to the French Open which starts on 25th May. Rafael Nadal is of course the top clay court specialist and has also reclaimed the World number one status this year following his injury problems, so it is no surprise that he is currently favourite to win all the clay court tournaments leading up to the French Open. Those who enjoy gambling on tennis will however know that any one of the top four players is capable of winning on the day, so there can be some excellent gambling opportunities available. The Monte Carlo Open for instance is now underway, and although Nadal is 8/11 favourite with Novak Djokovic second favourite at 13/8, you can get odds on Roger Federer of 9/1 with Paddy Power. Those odds on a player with the talent of Federer must be an attractive proposition for aany tennis gambling fan who does not believe that Federer is a spent force.
