Fifth Italian banned for betting
Luzzi has been banned from playing for 200 days
The world number 139, who plays mainly on the challenger circuit, was found guilty of gambling on 836 matches.
Luzzi, 28, has been suspended for 200 days and fined US$500,000.
Fellow Italian Giorgio Galimberti was banned earlier in February, following compatriots Potito Starace, Daniele Bracciali and Alessio Di Mauro.
Luzzi was found by the ATP to have “wagered 273 times on 836 tennis matches between May 2004 and April 2007″ and once placed a bet on himself to win a match.
However, the ATP confirmed the player was not found to have made any attempt to “affect the outcome of any tennis match”.
The fine of US$500,000 is considerable, bearing in mind Luzzi has career earnings of US$540,892.
