Marat Safin has been fined $2,000 for unsportsmanlike conduct during his first-round win over American Vince Spadea at the U.S. Open, the International Tennis Federation said on Thursday.
Safin lost his temper and argued with umpire Carlos Bernades after he was controversially foot-faulted on a second serve late in the fourth set against Spadea on Tuesday.
With Bernades refusing to overturn the call -- which gave Spadea set point -- Safin swore at the official and for a while refused to play on.
The former world number one eventually calmed down and won the match in five sets.
