LONDON: A Croatian umpire who worked at the US Open despite being suspended for betting offences has been given a 10-year ban, the International Tennis Federation (ITF) announced on Tuesday. Denis Pitner was originally banned for 12 months last August after passing on fitness details of a player to a coach and accessing a betting account used to place bets on tennis matches. But an error by the United States Tennis Association meant that he was able to work as a line judge at Flushing Meadows during last year’s tournament. “The International Tennis Federation announced today that tennis official Denis Pitner, of Croatia, has had his ITF officiating certification suspended for a period of 10 years after being found guilty of offences under the Code of Conduct for Officials,” the ITF said.
