LONDON -- Novak Djokovic was embroiled in a tetchy exchange with reporters after defeating Dominic Thiem in his Tour Finals opener.The Serb -- who was overtaken as world No. 1 by Andy Murray this week -- had earlier appeared to vent his frustrations after losing a first-set tiebreaker in his 6-7 (10), 6-0, 6-2 victory.He nearly tagged his coach Boris Becker with a ball seemingly struck in the direction of his players box, and was given a code violation by chair umpire Carlos Bernardes.It was suggested to Djokovic in his postmatch news conference that he had been close to potentially hitting a spectator in the crowd, which could have resulted in him automatically defaulting the match.It didnt go down well with him. You guys are unbelievable, he said. Youre always picking these kind of things.Im close? Im still not suspended, so if Im not close, Im not close. It could have been [serious], yes. It could have snowed in the O2 arena, as well, but it didnt.Im the only player that shows his frustration on the court? Thats what you are saying?It is not an issue for me. Its not the first time I did it.Indeed, Djokovic also flirted with more serious punishment when he vented his frustrations in the Roland Garros quarterfinals earlier this year.After missing a break point in the second game of the third set of that 6-3, 7-5, 6-3 win against Tomas Berdych, Djokovic went to smash his racket into the dirt, only to see it slip out of his hand and fly into the back wall on Philippe Chatrier Court.Djokovic admitted at the time he was lucky -- had he hit the nearby line judge, who was forced to take evasive action, he could possibly have been disqualified.Instead, he escaped with a warning for racket abuse after quickly apologizing to chair umpire Eva Asderaki Moore in Paris.[It was a] high intensity, high level of tennis in the first set, Djokovic continued in his news conference. We didnt really give each other too many chances. I think we each only had one break point. We both went for shots. A lot of long rallies. It was over an hour, the first set.When I had the great comeback of saving six set points, then I didnt manage to win that first set, of course youre frustrated. On the other hand, you know, I think I managed to kind of compose myself and really gather all my attention and concentration to what was coming up after that.The great start of the second set helped me to regroup.Djokovic is chasing a record-equaling sixth Tour Finals title in London, which would see him immediately regain the No. 1 ranking form Murray.Cheap Nike Shoes UK Online .
