LONDON - Former champion Maria Sharapova saved six match points before falling to Angelique Kerber in the fourth round at Wimbledon on Tuesday, ending her bid to win a second title at the All England Club a decade after her first. Wholesale Hockey Jerseys Store . Five-time champion Serena Williams, meanwhile, struggled to even hit the ball over the net in a doubles match with sister Venus and pulled out after only three games with what officials called a viral illness. Sharapova, a five-time major champion, saved one match point at 5-2 down in the third set and five more in the final game before hitting a backhand long on the seventh. That gave the ninth-seeded Kerber a stirring 7-6 (4), 4-6, 6-4 win on Centre Court in a match that lasted 2 hours, 37 minutes. "Its unbelievable," said the German, a semifinalist two years ago. "It was so tough (a) match. Every single set was so close. Marias a great player. I was just fighting, concentrating and focusing on myself. Im so happy to be in the quarters now." Kerber will next face 20-year-old Canadian star Eugenie Bouchard, the only woman to reach the semifinals this year at both the Australian Open and French Open. Bouchard beat Kerber in the fourth round at the French. Sharapova, who won her first Grand Slam title at Wimbledon in 2004 at the age of 17, was coming off her latest major championship at the French Open last month. "Its absolutely normal for people to have high expectations of me doing well in Grand Slam stages," Sharapova said. "I certainly do, as well. Today could have gone either way, and it didnt go my way." On a day when seven-time mens champion Roger Federer sailed into the quarterfinals, Serena was out of sorts from the moment the pre-match warmup began. She had trouble collecting tennis balls from the ball kids and missed completely on some practice strokes. The start of the second-round doubles against Kristina Barrois and Stefanie Voegele was put off for about 10 minutes while Serena sat in her chair and was examined by medical staff. In the third game, Serena hit four double-faults. She hit serves that bounced before reaching the net. Umpire Kader Nouni climbed down from his chair and walked over to speak to Serena. The sisters walked to the sideline holding hands, and the match was stopped. Serena wiped away tears as she left the court. The Wimbledon referees office and WTA said Serena had a viral illness. She left the grounds a few hours later in a tournament car with Venus. While Sharapova sought to dictate play with her big-swinging groundstrokes, Kerber played counter-attacking tennis and went for her shots when the opportunities came. The match featured high tension and intensity. Sharapovas shrieks grew louder and louder as the match wore on. Kerber went up 4-1 and saved two break points to lead 5-2 in the final set. She held a match point on Sharapovas serve, but the Russian hit a deep backhand that she couldnt handle. With Kerber serving for the match in the next game, Sharapova broke for 5-4. Then Kerber went up 0-40 on Sharapovas serve, but the Russian erased those three match points. Two more came and went. Sharapova twice earned game points but couldnt convert. Finally, on the sixth match point of the game, it ended with Sharapovas backhand error. Federer kept up his bid for a record eighth Wimbledon title by beating Tommy Robredo to reach the quarterfinals for the 12th time. Federer, who has not dropped a set in the tournament, overwhelmed the Spaniard 6-1, 6-1, 6-4 in just over 90 minutes. "All the things are happening that need to be happening to go deep in this tournament again," he said. Federers win set up an all-Swiss duel with Australian Open champion Stan Wawrinka, who beat Feliciano Lopez 7-6 (5), 7-6 (7), 6-3 to make it to the quarterfinals for the first time. Eighth-seeded Milos Raonic became the first Canadian man to reach the Wimbledon quarterfinals since Robert Powell in 1912, beating No. 10 Kei Nishikori of Japan 4-6, 6-1, 7-6 (4) 6-3. The first woman into the semifinals was No. 23 Lucie Safarova of the Czech Republic, who beat Ekaterina Makarova of Russia, 6-3 6-1. French Open runner-up Simona Halep breezed into the quarterfinals with a 6-3, 6-0 win over Zarina Diyas of Kazakhstan. Her next opponent will be 2013 finalist Sabine Lisicki of Germany, who overcame shoulder trouble to defeat Yaroslava Shvedova of Kazakhstan 6-3, 3-6, 6-4. ___ Cheap New York Rangers Jerseys .

NEW YORK -- Steve Kerr said Sunday he spoke with Phil Jackson twice over the weekend and that they will continue discussing the possibility of him becoming coach of the New York Knicks. Kerr said he had dinner with Jackson, his former coach with Chicago and the new Knicks team president, on Friday night and they talked again Saturday. Kerr is in New York to work the game between the Brooklyn Nets and Toronto Raptors for TNT. "Theres a lot to cover on both sides and this was the first time weve talked about the job. It just opened up last week and so weve got a lot of things to discuss," Kerr said. Jackson fired Mike Woodson and the rest of the Knicks coaching staff after a 37-45 season, and again said he wasnt interested in returning to coaching. Though Kerr has never been a coach, he has been mentioned as a candidate for the job since Jackson was hired in March. Jackson said last week he hoped to speak with Kerr soon to see gauge his desire to do the job, and it definitely interests Kerr. "How could it not?" Kerr said. "I mean, its the Knicks and its Phil Jackson, my coach. So Id be crazy not to look into it." Kerr said he has wanted to coach since stepping down as Phoenix Suns general manager in 2010. He won three titles playing for Jackson in Chicago, and agreed with his former coach that they have similar views of the game. "I know Phil last week said we share the same space, which I think is well said," Kerr said. "Wee share a lot of the same philosophies. Cheap New Jersey Devils Jerseys. I learned a lot of my basketball from him and Tex Winter, and so I think its safe to say that we have a lot of the same ideas." Winter taught the triangle offence and was a longtime Jackson assistant when he used the system to win an NBA-record 11 championships as a coach. Jackson said he wont insist the Knicks coach run it, but has made clear his belief in it. Woodson went 109-79 with the Knicks, leading them last season to their first division championship since 1994, but was fired with a year left on his contract. He said Sunday on NBA TV that coaching the team that drafted him out of college was like a "dream come true." "And the last two years, prior to coming into this season, was a good two seasons for our ballclub and our fans. And this year things just didnt work out," Woodson said. "Sometimes in life things just dont work out according to plan. But I look at it, overall, it was a good run." Jackson said he doesnt have a timetable, though he hoped to have a coach in place by the July summer league. Kerr said it was tough to do things quickly because hes on the road so much of the spring working games. Hes been going to training camps and meeting with coaches, and wants to work with players instead of another role in a front office. "Ive been preparing for this and if its something that feels like the right fit, its something Im going to do," Kerr said. ' ' '
