This rash of Italian players being punished may be partly explained by cultural differences. For example, players from the United States know of the stigma of Pete Rose betting on baseball, even if they are a generation or two younger than the former Cincinnati Reds manager, and surely would be wary about gambling on their sport.
Tennis is the third most heavily bet sport (behind soccer and horse racing) in Europe and the explosion of online wagering has obviously made it easier for players with down time between matches, or during weather delays, to use a computer and make bets on sports, including tennis.
Quoted on ESPN.com regarding the Galimberti suspension and fine two weeks ago, the president of the ATP player council, Ivan Ljubicic of Croatia, said, “I personally believe the suspension [100 days] was too harsh, but I definitely agree that the fine [$35,000] was good enough, maybe even give them a little bit higher fine, but just let them play. They bet on matches they weren’t involved in. They just really didn’t know it was the rule. And the moment they realized they were doing wrong, they stopped.”
All the Italian players apparently wagered with the same online firm – the Austrian-based Interwetten.
