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. 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 Dave Henderson Jersey .cas NHL Play of the Year showdown continues today with a man whos spent most of his career on highlight reels and a goalie actually "reaching back" for a save.

Interim athletic director Jim Hackett made it official at a press conference, two days after Harbaugh departed as the head coach of the NFLs San Francisco 49ers. Hackett said it was a seven-year contract and various reports indicate it to be worth about $5 million per season plus incentives. We are excited to have Jim come home and lead our football program into the future, said Hackett on Tuesday. Since retiring from playing in the NFL, Jim has worked hard to become one of the elite coaches in the profession. He has been successful at every coaching stop and has done an exceptional job of molding and developing young men as football players, students and citizens. We believe that Jim is the perfect individual to balance the academic and athletic expectations that come with representing this football program and university. Harbaugh called his return to Michigan a third Homecoming. His father was an assistant coach at Michigan under Bo Schembechler from 1973-79, and Harbaugh was a quarterback for the legendary coach from 1983-86. Throughout my life I have dreamed of coaching at the University of Michigan, said Harbaugh on Tuesday. Now its time to live that. Harbaugh played 14 seasons in the NFL before embarking on a coaching career that also included collegiate stops at San Diego and Stanford before his hhighly successful four-year run with the 49ers.dddddddddddd After a 29-6 record in three years at San Diego, he turned the Stanford program into a Pac-12 powerhouse. The Cardinal went 29-21 in his four years, including a 12-1 mark with an Orange Bowl victory in 2010. The 49ers didnt have a losing season under Harbaugh, reaching the NFC title game in each of his first three seasons with a Super Bowl appearance after the 2012 campaign. San Francisco lost that Super Bowl to Baltimore, coached by his brother John. This years 49ers team went just 8-8 amid swirling rumors all season over his job security. Harbaugh will become the 20th head coach in Michigan history and will replace Brady Hoke, who was fired in early December after a 5-7 season. Hoke was 31-20 during his Michigan tenure, losing more games each year following an 11-2 debut in 2011. Im honored and humbled, said Harbaugh, who will be the sixth former Michigan player to lead college footballs winningest program. Harbaugh was one of the most efficient passers in NCAA history during his time at Michigan, leading the nation in passing efficiency in 1985. He led the Wolverines to a 21-3-1 record as a full-time starter during his final two seasons, including a pair of victories against rivals Michigan State and Ohio State. Michigans last two coaches, Hoke and Rich Rodriguez, were a combined 2-12 against the Wolverines biggest rivals over the past seven years.
