Novak Djokovic was jeered by the crowd during a 6-2, 6-7(7), 6-4 loss to Olivier Rochus in his opening match at Miami, producing a sub-par performance that included 62 unforced errors.
"I was just kind of waiting for him to make the shots, and it wasn't the right approach," said Djokovic, who reached the final last year. "He was making me run a lot, so points were really long.
"I don't feel great on the court, and everybody could see that."
