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.

RENTON, Wash. -- Richard Sherman felt good enough on Wednesday to break out his Halloween costume a little early, donning a cape, grabbing a wand, and presenting a very authentic Harry Potter look.It was a drastic difference from late Sunday night and into Monday morning when Sherman was suffering from dehydration and fatigue on the flight back to Seattle after being on the field for nearly 100 plays and more than 46 minutes of game time in the Seahawks 6-6 tie with the Arizona Cardinals.Five quarters of football is pretty tough. But Quidditch -- the Beaters, the Chasers, trying to find the Golden Snitch -- is tough, Sherman said Wednesday. Five quarters of football, though, in that element, that takes the cake.In all seriousness, Sundays tie with Arizona left the Seahawks defenders exhausted. Never before had a Seattle defense been on the field longer and the effects were notable.Between special teams and defense, strong safety Kelcie McCray was on the field for 108 plays, the most of any player in the NFL this season. Linebackers Bobby Wagner and K.J. Wright were on the field for 102 total plays. Sherman and Earl Thomas played 99 plays and DeShawn Shead was in for all 95 defensive snaps.It was an exhausting experience and three days later those involved were still trying to recover.I didnt know how much it was but I did know it was a long time, McCray said.Arizona held the ball for 46 minutes, 21 seconds Sunday. According to the Seahawks, that was the 11th-highest total for any regular-season game since time of possession was first tracked in 1977. Sherman wasnt the only one who needed IV fluids. Wagner left at one point during the game to get fluids in the locker room and missed only one play.Sherman seemed to have the most side effects from the game, being told afterward he was suffering effects of heat exhaustion. Sherman said it wasnt until Tuesday night that he started to feel normal again.They said I had a fever, but I had the shivers. It was bad, bad stufff, Sherman said.dddddddddddd Probably around the third quarter, third quarter my legs started locking up. After a while you just kind of deal with it. Got to finish the game.Shermans body seemed to fail him on one play in particular in overtime where he attempted to undercut a throw for J.J. Nelson but couldnt get any push from his legs to break up the play. Nelson caught the pass and if not for McCrays effort to tackle him inside the 5, the game would have been over.At first I thought it was going to be a touchdown. I was like `this guy is about to score, game over. I just ran as fast as I (could) and gave everything I could to get him down, McCray said.Coach Pete Carroll revamped his Monday schedule to give players a few extra hours of sleep and some of the key contributors were expected to get a lighter amount of practice time this week in preparation for a long road trip to New Orleans.Right from the beginning leaving the locker room, we were talking making sure that throughout the next couple days that rest is really important, eating properly and getting everything all balanced back again, Carroll said. Weve been all over that. That kicks us really back to today, were in pretty normal mode, but were still accounting for those guys that had the big workloads and were going to take that into account as we measure the reps during the course of the week.Game notes Seattle is still unsure who will start at left tackle. Bradley Sowell suffered an MCL sprain in his right knee on Sunday but was trying to convince Carroll and the training staff he could play. Rookie George Fant, rookie Rees Odhiambo and veteran JMarcus Webb are the likely candidates if Sowell is held out. ... Seattle released veteran RB C.J. Spiller and signed FB Will Tukuafu on Wednesday.---AP NFL website: www.pro32.ap.org and AP NFL Twitter feed: www.twitter.com/AP-NFL ' ' '
