Its not easy to find a weakness in Roger Federer, who is seeking an eighth Wimbledon title and an 18th Grand Slam triumph. Pat Elflein Womens Jersey . Lets keep this between ourselves for now, but the Wimbledon Diary thinks it might have done just that.So far during The Championships, Federer has been successful with just 12.5 percent of his Hawk-Eye challenges, with just one correct query from the eight times he has called upon the technology. Contrast with his quarterfinal opponent, Croatias Marin Cilic, who has a hit-rate of 61.5 percent during the tournament to date, with eight correct challenges from 13 attempts. Of the eight men left in the singles draw, only one has a lower percentage than Federer -- thats Frenchman Lucas Pouille, who was wrong with all six of his, so is lingering on zero.In Novak Djokovics absence, Andy Murray is the highest seed left in the tournament, but he could also do some work on this part of his game -- he has been successful with 23.1 per cent of his challenges, with three from 13. The overall average for the mens singles so far is 30 percent, with the same number in the womens event, too.Golden Bear spotted in SW19Jack Nicklaus, who has been in the Royal Box for the past couple of days, is more than just a tennis fan. The golfer, who won 18 majors, has previously played some small part in tennis history -- the Williams sisters have been known to practice in the grounds of his Florida home. Nicklaus has three grass courts in his back garden.Serena aces the numbers gameAside from 22, which is how many Grand Slams Serena Williams will have if she lifts the Venus Rosewater Dish on Saturday, theres one number that fascinates her coach Patrick Mouratoglou. That number is 102, which is how many aces Williams served during the 2012 Championships. That was the first Grand Slam that we won together and she served at a higher level than I think anyone in the history of the sport, the Frenchman told the Wimbledon Diary. She served more aces in that tournament than any woman or man -- and you have to remember that the men would have been playing over five sets. Thats crazy. Her serve is just a huge weapon on grass.Passing the Wimbledon smell testUsed tennis balls can be bought from a kiosk outside Centre Court. No doubt a few tennis fans will be sniffing the Slazenger balls before using them at their local courts. Thats inspired by Slovakian Dominika Cibulkova, a quarterfinalist in the womens singles, who successfully identified a ball from each of the four Grand Slams on smell alone.

I dont know if I can quantify how far off or things like that that they might be but I would say we continue to have dialogue. Dalvin Cook Jersey . Down by seven with 90 seconds left in regulation, thats where they looked comfortable. http://www.vikingsauthoritystore.com/Authentic-Ben-Gedeon-Vikings-Jersey/ . Ibaka equaled a career high with 20 rebounds, adding four blocked shots and 15 points as the Thunder smothered the Milwaukee Bucks offence in a 92-79 victory Saturday night. MANKATO, Minn. -- In mere months, Alex Boone has established himself as the alpha male of Minnesotas offensive line.Heavily tattooed and 6-foot-8 and 310 pounds with the boisterous personality to match, Boone is already the standout in a group that has collectively struggled in recent seasons. The edge he brings to playing left guard is part of why the Vikings gave him a four-year contract this spring worth as much as $26.8 million.Humility has helped spur his development, too. Being bypassed in the 2009 NFL draft after alcohol-fueled off-the-field trouble led to a sobering up. Then there was Sept. 23, 2012, when Boone and the San Francisco 49ers came to the Metrodome to take on the Vikings hed one day be playing for.Boones opponent in that game was Kevin Williams, who recently retired after 13 seasons and five All-Pro selections. Nearly four years later, the memory of being dominated that afternoon by a defensive tackle seven years older than him is still beneficially vivid.I thought, `Hes just old. He aint got it anymore. Hes not going to do anything, Boone said, and he just beat me all up and down the field. He made me a better player, and it really opened my eyes to the league.The lesson about overconfidence came in his first season as a starter on a team that advanced to the Super Bowl.I told him during the game, too, that hes probably the most respected person in this game because of what he did to me, Boone recalled upon reporting to training camp last week.Boone received a roaring ovation that day from the autograph-seeking fans as the players filed into their residence hall att Minnesota State University, a sign of the angst that has surrounded the front five in Minnesota in recent years. Ben Gedeon Womens Jersey. Boones presence will loom large for quarterback Teddy Bridgewater and the Vikings.Hes brought an attitude, lots more character to the room, right guard Brandon Fusco said.Tony Sparano was hired as the new offensive line coach, too, another critical injection of tenacity. Left tackle Matt Kalil, his hands full in practice with defensive end Everson Griffen, has pleased the staff in camp so far with his performance. Center John Sullivan has returned from two back surgeries that erased his 2015 season to compete with Joe Berger for the starting job. Newcomer Andre Smith is on track to be the right tackle next to Fusco, who has shifted to his original spot.If everybody believes in the same thing and buys into the same thing that were going to be the toughest, the meanest, the nastiest group, its not going to take very long for everybody to get on the same page, Boone said. I think its crucial that everybody does buy into that.Coach Mike Zimmer said hes already noticed the attitude effect on the locker room. A conversation with linebacker Chad Greenway confirmed this.He said, `Hes great. People respect him, Zimmer said. He has kind of changed the mentality of the offensive line room, him and coach Sparano, and thats a good thing.---Online:AP NFL website: http://www.pro32.ap.org and AP NFL coverage on Twitter: http://www.twitter.com/AP-NFL Cheap NFL Jerseys Cheap NFL Jerseys China Cheap Jerseys From China Cheap NFL Jerseys Authentic Wholesale Jerseys China Cheap NFL Jerseys China NFL Cheap Jerseys Cheap NFL Jerseys ' ' '
