WIMBLEDON -- Annika Beck was to Serena Williams on Sunday what a decent cup of morning coffee is to the rest of us.If the six-time Wimbledon champ needed a little jolt to pass Chris Evert for Grand Slam match win No. 300, Becks early service break on Centre Court seemed to do just the trick.Playing on the first middle Sunday here in 12 years, Williams shook off her boredom or whatever made her look like she woke up in a bad mood, and like the aftermath of the infamous racket smash in her previous match, she went to work.Winning 11 of the last 12 games, including the last seven, Williams polished off the 43rd-ranked German 6-3, 6-0 in 51 minutes to reach the fourth round at Wimbledon.I think the [Christina] McHale match really helped me, Williams said, referring to her second-round encounter last week. To be honest, I felt like losing that first set so tight and her playing better than shes ever played in her life really helped me to realize that I can play better.Williams coach, Patrick Mouratoglou, told ESPN.com on Saturday that Serena was too calm at the French Open, where she was defeated in the final by Garbine Muruguza. He was glad to see a little rage in her racket-smashing moment during a changeover against McHale.On Sunday, Williams was aggressive only in her on-court play, finishing with 25 winners to only 14 unforced errors. Williams cracked seven aces and limited Beck to four points in the second set, all on the return of serve.I wasnt sure what the stats were, obviously, but on that last service game, I was thinking, Have I lost on my first serve yet? Williams said. I wasnt sure, but I just tried to stay focused.It gives me a lot of confidence. I know what it takes to win these tournaments. Its just about now just doing it.Clearly that is tougher than it looks, as another No. 1 can attest.Asked what she thought of watching fellow American Sam Querrey derail Novak Djokovics pursuit of a calendar-year Slam on Saturday, Williams said she was surprised Djokovic didnt come back from his two-set deficit to win.But it happens to all of us, said Williams, who lost her bid to sweep all four majors when she was defeated in last years US Open semifinals. Every time I step out on the court, if I dont win, its major national news. But if I do win, its just like a small tag in the corner.If that sounds like a burden, Williams said it isnt any longer.I look at it almost like something thats really awesome to be in that position. There are only two people you can say that about out of all the athletes, Williams said of herself and Djokovic.Williams will next face 13th-seeded Svetlana Kuznetsova, who rallied back from a 5-2 third-set deficit to eliminate American Sloane Stephens 6-7 (1), 6-2, 8-6.Williams is 9-3 against her upcoming Russian opponent, although Kuznetsova won their last meeting, a three-set upset at the Miami Open in March. The two have yet to play on grass.Were both ready for this match, Williams said. Were both going to give it our heart, as we always do when we play each other.While Mouratoglou has worried about Williams level of motivation since the US Open, during which time she finished as the runner-up at both the Australian and French opens, he said it is definitely not OK with her to finish anywhere short of winning the title and maintaining her No. 1 ranking.She hates [losing], Mouratoglou said. Shes not losing in the second round, third round, quarters. She was two times in the final and two sets away from the Grand Slam, so this is definitely not satisfying at all to stop there.Serena wants to be No. 1. She wants to win Grand Slams because when you win Grand Slams, you are a champion. If she feels she is not a champion anymore, then she will not enjoy it and she wont play.Custom Arizona Cardinals Jerseys .Y. -- Bills receiver Stevie Johnson has a bone to pick with the NFL schedule maker.

Numbers Game looks into the Canadiens securing the services of Thomas Vanek in a trade with the New York Islanders. The Canadiens Get: LW Thomas Vanek and a conditional fifth-round pick.Anthony Joshua has named Rob McCracken as his full-time coach.McCracken will be in Joshuas corner when he makes the latest defence of his IBF heavyweight title against Eric Molina at the Manchester Arena on Dec. 10.Joshua excelled under McCracken as an amateur, eventually winning an Olympic gold medal at London 2012 before turning professional in 2013.The 27-year-old will now be trained by McCracken after an agreement was reached to combine the new role with his position as performance director of Team GB boxing.Tony Sims had overseen Joshuas impressive progress as a professional but rumours had long persisted in boxing circles of the London fighter spending more time working with McCracken.It is little secret that, as with Carl Froch who McCracken also successfully guided as a professional, Joshua spent a significant amount of time training with the GB boxing squad at the English Institute of Sport in Sheffield. Sims -- one of Britains busiest trainers -- will continue to assist McCracken.I have remained close to Rob and the GB Boxing squad since 2012, Joshua said. I have consistently turned to him for advice and gguidance so I am really excited to have him in my corner.ddddddddddddI would like to put on record my thanks to Tony Sims who will remain in my corner working with Rob as he did to such success with Carl Froch.The 48-year-old McCracken, who once challenged for the WBC middleweight title having also been the Commonwealth champion, added: Anthony is a special talent.I am looking forward to working with him on the next stage of his career as he looks to defend his titles and, ultimately, to unify the heavyweight division.I know from working with Carl Froch that combining my work coaching a top professional boxer with the role of performance director has mutual benefits and that having a world champion in the gym has a very positive impact on the whole of the GB Boxing squad.It gives the boxers an insight into what it takes to be the best in the world and provides top-class training opportunities that will help to develop and improve the heavyweight and super-heavyweight boxers in the squad.
