Novak Djokovic raced into the third round of the French Open after he was booed by the Roland Garros crowd.
The defending champion was 5-4 ahead in the first set against Roberto Carballes Baena when he complained to chair umpire Nico Helwerth that a spectator had called out as he chased down a drop-shot.
Djokovic was jeered by some of the fans on Court Philippe Chatrier – and he promptly won 13 of the next 16 games to claim a statement 6-4 6-1 6-2. victory.
The world number one said: “He shouted actually a few words during the rally.
“I mean, when Carballes Baena made a drop-shot and as I was running, he was there in the first row – and he started from the beginning of the match.
“He went on several times, which was fine, he was supporting my opponent, but I thought that this was a bit of a hindrance as he was so close and then, you know, as I was about to hit the ball, he was shouting.
“So that’s what I asked the chair umpire, but he explained that he cannot call that a hindrance. That’s it. Very simple.
“At times they are not easy and I have been having some love affairs with the fans here – and also some tough matches, some tough seasons. I have experienced both sides.
“Obviously you always want to be the one that they support or at least have kind of a neutral atmosphere on the court, but it’s not possible always for that to happen.”
