Andy Roddick has revealed he once pinned Novak Djokovic up against a locker in the changing room after a match and a fight was only prevented by the presence of the Serbian's trainer.
The altercation came after their quarter-final at the 2008 US Open, an encounter filled with tension after Roddick had previously accused Djokovic of faking injuries.
The just-displaced world No1 won in four sets and bit back at the American in an on-court interview, prompting the Flushing Meadows crowd to jeer him.
Roddick told the story on a US TV show yesterday about a "tennis player" whose name rhymes with "Schmovak Schmokovic".
"I was talking trash, and he came out and beat the pants off me, as he would, but then kind of chirped afterwards," Roddick said. "So he comes straight in, I went right up to him, had him up against the locker. But then I realised his trainer was a little bit bigger than Donovan [McNabb, an NFL player] and I kind of checked myself."
