Nike Air Max 90 For Sale Cheap .Wozniacki won 7-6 (4), 6-7 (5), 6-2 to beat Sharapova for the second-straight time, having also won in the fourth round of the U.S. Open. Tuesdays result in the round-robin match dealt a major blow to Sharapovas hopes of claiming the year-end No. 1 ranking.Wozniacki, who has always been regarded as one of the fittest players on tour, said her additional running work in preparation for the marathon had taken her stamina to a new level and also given her added belief in Tuesdays 3 hour, 15-minute match.I just feel like right now with all the training and running Ive been doing I can keep being out there and keep running, Wozniacki said. I kept thinking to myself out there in the third set, If youre going to get tired now, how are you going to get through this marathon? You better keep going.As much as she believed the training had helped her aerobic fitness, she said the marathon will be a one-time-only affair and not one that she would recommend to other players.To do it year in and year out, I dont think its possible, Wozniacki said. Our bodies get a beating already. I dont think its necessary to do this again while Im on tour.No such stamina was required in Tuesdays other match as Agnieszka Radwanska had a comfortable 6-2, 6-3 win over Wimbledon champion Petra Kvitova.It was an impressive performance by the Pole, who had been beaten in straight sets the past two times she had played Kvitova. It was the fourth successive year in which the pair had faced each other in their opening matches at the WTA Finals.Sharapova had 15 double-faults, including two while serving for the first set, and 76 unforced errors. Wozniacki finished the match, which had 12 breaks of serve, with 35 unforced errors.The defeat in her opening round-robin match means Sharapova now needs to at least reach the final in Singapore and hope Serena Williams loses her two remaining group matches if she is to overtake the American and finish the season with the top ranking for the first time.Having staved off a set point against her in the 10th game, Wozniacki took the first set by winning the final five points of the tiebreaker.Wozniacki went up a break early in the second, but relinquished the advantage in the sixth game as she complained to the chair umpire about swirling lights which suddenly came on during the middle of a point and remained on for the rest of the game.The Dane recovered quickly after dropping the set, breaking Sharapova early in the third and then twice more to end it.Sharapova was frustrated by her error-strewn performance, blaming her mistakes rather than Wozniackis play for her two consecutive losses to the Dane.Its happened the last couple of times I played against her, Sharapova said. The chances that you have when youre serving for a set, its in your hands to finish that off.When you give those chances back, a player thats top 10 in the world and has the experience as Caroline does, youre not just going to run away with the match.The losses by Sharapova and Kvitova have thrown the White Group wide open, with Radwanskas convincing victory highlighting her title credentials.The Pole has not performed at her best in past appearances at the season-ending event, having been eliminated at the group stage in three out of four years.I feel much better than last year at the championships, Radwanska said. I havent played many matches in the past two weeks, which has helped.Ive learnt my lessons from past years about how to play at my best.The match started after 11 p.m. local time, when Kvitova said normally I am sleeping, and began as an even contest. But Radwanska managed breaks in the Czechs last two service games of the opening set, and then won the final three games of the second set to record a convincing victory.Kvitova, who won only two points on her second serve during the second set, said Radwanska did not produce anything really special but she struggled to read the pace of the court.Sometimes was so fast and so slow, so was really difficult for me to find the timing, Kvitova said. My serve was OK, but she returned a lot of balls back, which is always difficult for me, to then play rally with her.In Wednesdays matches, Williams will face Simona Halep while the other Red Group match will be Ana Ivanovic against Eugenie Bouchard of Westmount, Que.

However, Therrien added that Galchenyuks status for next Wednesdays game against the Detroit Red Wings is questionable. Galchenyuk has been out since Jan. 6 with a broken right hand.NASHVILLE, Tenn. - Jake Locker practiced Wednesday for the Tennessee Titans, and now the quarterback will see how his right wrist responds to a full session of throwing the ball.Locker isnt overly concerned, he expects to play Sunday against the Cleveland Browns.Thats the way Im going about it, Locker said.The quarterback says he feels really good and was able to do everything Wednesday, which he calls encouraging. Locker lobbied coach Ken Whisenhunt to play in last weeks 41-17 loss at Indianapolis but watched from the sideline as backup Charlie Whitehurst played. Locker says its always tough staying on the sideline.Whisenhunt still wants to see how Locker feels Thursday after a full practice. The Titans want to make sure all the soreness is out of Lockers wrist, which he injured in a 33-7 loss at Cincinnati on Sept. 21, because the quarterback easily could put his hand down to the ground bracing himself risking further injury.He did a lot today, and if it responds the way we think its going to, then everythings good, Whisenhunt said.Having Locker back is one thing. The quarterback playing better is another. Locker has struggled in his last two starts and had four interceptions in those games. The Titans also didnt score a single point in the first half of either of those losses, a trend they finally ended with 10 points in Indianapolis with Whitehurst last week.Asked what he needs Locker to do better, Whisenhunt said everybody has to play better.Its hard to single out any one person, because there are a lot of things, Whisenhunt said. First of all, weve got to quit turning the ball over, weve got to make plays on thhe ball defensively, special teams weve got to do a better job. Discount Air Max 90. . I could go on. There are a lot things that we need to improve.Locker started off the season strong throwing for 266 yards and two touchdowns in a win at Kansas City, a victory that looks more impressive with the Chiefs routing New England on Monday night. Locker said he has looked at what he didnt do well through the first month of the season, and he thinks being more precise on details in each play can make a big difference.When youre not winning and things arent going the way youd like them to go, Ive always believed the first place you have to look is yourself, Locker said. And its no different in this situation.The Titans (1-3) host the Browns (1-2) on Sunday having lost three straight. Theyve also been outscored 100-34 in this skid, and Whisenhunt has said he will simplify the offence a bit to help the Titans. Locker said that can help players not be as mindful and play faster.Its something I think is an effort on coachs part for us to really hone in and focus on the smaller details within each play and execute them really crisply all 11 guys, Locker said.Notes: CB Blidi Wreh-Wilson (concussion) did not practice, and Whisenhunt said theres a possibility Coty Sensabaugh replaces him if the cornerback is not cleared in time before Sunday. ... TE Taylor Thompson (knee) did not practice. TE Delanie Walker (shoulder) was limited.
