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. Rashan Gary Jersey .J. -- Seven games into a disappointing season, New York Giants defensive catalyst Jason Pierre-Paul is getting the feeling hes back. Rashan Gary Youth Jersey .S. -- Nikolaj Ehlers registered a hat trick for the third straight game and Jonathan Drouin had a goal and five assists as the Halifax Mooseheads hammered the host Cape Breton Screaming Eagles 10-1 on Tuesday in Quebec Major Junior Hockey League action. http://www.packersrookiestore.com/Packers-Dave-Robinson-Jersey/ . Breaking three of his own world records on his way to winning in Paris, Chan silenced the critics and left the audiences standing in appreciation and awe. Jaire Alexander Youth Jersey . -- Al Jefferson found a groove just in time for the Charlotte Bobcats. Brett Favre Jersey . Boucher previously coached the Tampa Bay Lightning and had a 97-78-20 record over two-plus seasons. He was dismissed by the team last March after the Lightning struggled in the lockout-shortened season with a 13-18-1 record.Brent Seabrook scored in overtime, again, and the Chicago Blackhawks won Game Four, 6-5 over the Boston Bruins, evening the series at two games apiece. Seabrook, who has three goals and four points in the entire playoffs, has two overtime winners, his earlier one coming in Game Seven of the second round against Detroit. The Blackhawks outshot the Bruins 47-33, tying Bostons worst shot deficit (-14) in a game this postseason. The Bruins had a shot deficit of minus-14 or worse twice in the 2013 regular season. Chicago shook up their lines heading into Game Four, putting Patrick Kane on the right side with Jonathan Toews at centre and Bryan Bickell on the left wing. The results were favourable, as Kane had a goal and an assist, Bickell had two assists and, not only did Toews score a goal, but his positioning in front of the Boston net was instrumental to Seabrooks game-winning goal. Kane, Toews and Seabrook were plus-2 for the game, while Bickell and Duncan Keith were both plus-3. As the Blackhawks basically didnt use D Nick Leddy, playing him a total of 2:37, it was imperative to get a strong performance from veteran Michal Rozsival, who had two assists, was plus-3 and had strong possession numbers while playing 26:36, second-most on the Blackhawks, behind Keiths 32:37. Bruins D Andrew Ference struggled in the possession Game Wednesday, spending most of his night matched up against Chicagos second line of Patrick Sharp, Michal Handzus and Marian Hossa. Sharp had a game-high eight shots on goal and scored the Blackhawks fifth goal. Bruins C Patrice Bergeron scored twice and ledd the Bruins with six shots on goal, though he was minus-2.dddddddddddd. RW Tyler Seguin, LW Brad Marchand and D Zdeno Chara were minus-3 for the game. Chara was a minus-3 once in the regular season and its the first time in the playoffs hes finished worse than minus-1 in a game. Chara and Bruins RW Jaromir Jagr each contributed a pair of assists. On for two goals for and still minus-3, Chara was on the ice for five goals against. Bickell led the Blackhawks with six hits; Bruins LW Milan Lucic had a game-high eight hits and D Dennis Seidenberg registered seven. With the series now even, and heading back to Chicago, the advantage slides to the Blackhawks, but its ever so slight. There is such a razor-thin line between winning and losing in a series that has seen three of the first four games go to overtime, that neither team has a decided edge. The Blackhawks simply have to like being even in the series with the opportunity to get matchups on home ice in two of the remaining three games in the series. If they also happened to figure out how to beat Bruins G Tuukka Rask (who still leads the playoffs with a .941 save percentage), that could play in their favour. This series has been all about ebbs and flows, though, with momentum gained and lost over the course of single games. Its a wonderfully competitive matchup, so pretty great that there will be at least two more games between Boston and Chicago.
