ISTANBUL, Turkey -- Top-ranked Serena Williams breezed past Angelique Kerber 6-3, 6-1 to open her bid for a fourth ATP Championships title on Tuesday. Adidas Superstar 2 Hombre . Williams, the defending champion, had no trouble against Kerber, who also lost to the American 6-4, 6-1 in the round-robin at this event last year. Kerber was the only player to beat Williams last year - in Cincinnati - after the Americans first-round ouster at the French Open. "Today she was playing unbelievable, and I had actually no chance. I mean, she was serving great and also returning unbelievable," Kerber said. "So I was just giving all I could, but yeah, its tough to play against Serena like this." Williams was particularly effective with her backhand return, the shot she also used on her first match point. Kerber, who had two straight double-faults to surrender the first game of the second set, produced another to give Williams three match points. Although she is 32, considered a ripe age in tennis, Williams is enjoying the finest season in her career, having already won 10 titles. She added the French Open and U.S. Open titles to bring her Grand Slam record to 17 championships and is 74-4 for the year. Earlier, second-ranked Victoria Azarenka overcame an erratic performance to beat an ailing Sara Errani 7-6 (4), 6-2 in the opening match of tournament. "I was a little rusty at the beginning. I think its a little bit expected after a break, and playing right away against a top player always makes it a little bit difficult," Azarenka said. Williams, making her eighth appearance in the event, is looking to become the first player to successfully defend the title since Justine Henin in 2007. If she achieves the feat, she would equal Chris Evert for third most WTA Championships with her fourth. Henin was also the last to win 10 titles in a season, in 2007. Williams has clinched the year-end No. 1 ranking for the third time in her career after 2002 and 2009. Errani hurt her right calf in the third game of the second set and took a medical timeout to have it treated. Several times after that she seemed to be bothered by the injury and to favour her right leg, although she returned after the medical timeout to break Azarenkas serve to level at 2-2. She did not win another game though. "In the tiebreaker I felt a pain in my calf on serve," Errani said. "The first set was very tough, very long. I was running a lot." Errani served for the set three times -- and dropped serve each time as both players produced sloppy play with little rhythm. Azarenka, the Australian Open champion, managed to hold her serve only once through the first eight games but seized her chance when it came. She won four straight points in the tiebreaker to take a 5-3 lead, then faltered when she served her sixth double-fault. But an error by Errani gave Azarenka two set points. Errani then committed a double-fault and Azarenka had the set. "I think, overall was important to take that first set. It was a big turnaround point," Azarenka said. Azerenka, who was runner-up in the event in 2011 and a semifinalist last year, finished with eight double-faults but she also had 51 winners for Erranis 28. Azarenkas win was her first since losing the U.S. Open final to Serena Williams. Azarenka lost both of her opening matches in Tokyo and Beijing, where she had 15 double-faults. The tournament brings together the top eight players in the world. Third-ranked Maria Sharapova dropped out with a shoulder injury. The players are split onto two round-robin groups, with the top two finishers from each pool advancing to the semifinals.

PETERSBURG, Fla.CHICAGO -- First-time manager Rick Renteria is focused on the future of the Chicago Cubs, rather than their past failures. Renteria preached accountability Thursday when he was introduced via teleconference as the franchises 53rd manager. He takes on a challenging job that goes beyond merely trying to bring a winning team to Wrigley Field. The development of young ballplayers has been labeled as one of his strengths. And with Starlin Castro and Anthony Rizzo needing help, the former San Diego Padres bench coach has got lots of work ahead of him with a team that finished 66-96. "My personality doesnt allow for being counted out," Renteria said. "I think what were trying to do between the lines will speak for itself. In the end, were all judged in one fashion or another, but I dont preoccupy myself too much about what I thinks going to happen. I preoccupy myself with what I want to do." First thing he needs to do: Get healthy. Renteria will be introduced at Wrigley at a later date as he is recuperating in San Diego following hip surgery in October. The 51-year-old Renteria got a three-year contract with club options for 2017 and 2018. He is another unproven hire by team president Theo Epstein and the Cubs after the struggling organization initially expressed interest in New York Yankees manager Joe Girardi. Girardi, a Peoria, Ill., native and Northwestern product who once played for the Cubs, signed a four-year contract worth up to $20 million to stay with New York. "Ricks reputation is impeccable," Epstein said. "He stood out throughout the process to lead the Chicago Cubs into our next chapter." "You cant find anybody in this game to say a bad or neutral word about Rick Renteria," he said. The Cubs are relying on Renteria to improve on a 127-197 record during Dale Sveums two years as manager. Despite the franchises four consecutive losing seasons and a last-place finish in the NL Central in 2013, Renteria refused to accept the assumption that the Cubs wont be competitive next year. The Cubs last made the playoffs in 2008 and have not won a playoff game since 2003. Under Renteria, theyll be coming off their first last-place finish in seven seasons. Renteria, who has spent 30 years in pro ball, is the latest manager hoping to bring the Cubs their first World Series title since 1908. "I cant speak to whats happened in the past," he said. "I can only think about moving forward with the kids that we have and the product thats being placed before us." "I know it might sound naive, but I still believe that any team that goes in and plays between the lines has a chance to win a ballgame every single day," he said. "If I was to come in here and assume that we were going to lose, what kind of expectations am I laying for the players who are here?" Epsteein said the rest of the coaching staff with be announced in the coming days and will feature a mix of turnover and returning coaches. Zapatillas Nike Air Max 90 Outlet. Renteria does have history with the Cubs front office, which immediately put him on its radar when the managerial position opened. General manager Jed Hoyer and senior vice-president of scouting and player development Jason McLeod both worked with Renteria during their days in San Diego. "It was very clear when I was in San Diego that Rick was going to be a big league manager and pretty quickly," Hoyer said. Renteria spent the last six seasons in San Diego, the last three as bench coach. He also has coached in the Miami Marlins organization and in March managed Mexico in the World Baseball Classic. Besides Renteria, the Cubs interviewed former Mariners and Indians manager Eric Wedge, Rays bench coach Dave Martinez, former Nationals and Indians manager Manny Acta, former Diamondbacks manager A.J. Hinch and Brad Ausmus, who was hired by the Tigers on Sunday. The Cubs have dumped long-term contracts and traded most anyone of value in an effort to stock the farm system ever since Epstein was hired, hoping the payoff will be the sort of championship success he enjoyed in the front office in Boston. Among Renterias tasks will be getting the most out of Castro at shortstop and Rizzo at first base, two young players who have long-term contracts. Both were underwhelming last season and pitcher Jeff Samardzija had an up-and-down season. Renteria believes Rizzo, who he worked with in 2011 before getting traded to the Cubs, has a "tremendous future ahead of him." Settling in with his approach at the plate will be key, Renteria said. "Hes a very gifted athlete and obviously has some tremendous power," Renteria said. "He has a very good eye." With prospects Javier Baez, Jorge Soler, Albert Almora and Kris Bryant in the pipeline, the Cubs made it clear they want to provide the right environment for their young players to develop. Renterias bilingual background enhanced his resume with his ability to speak Spanish with Latin players. That will only help communication between the coaching staff and players, which was an issue at times the past two seasons. "Im hoping to be a good coach who happens to speak Spanish," Renteria said. "But I think the ability to communicate in the same language, it sometimes creates a bit of a comfort zone." Renteria was a minor league manager in the minors for eight years with the Padres and Marlins. That followed a 13-year playing career as an infielder that included all or part of five seasons with the Pirates (1986), Mariners (1987-88) and Marlins (1993-94). The 1980 draft pick was a career .237 hitter with 20 doubles, four home runs and 41 RBIs in 184 major league games. cheap jerseys Cheap NFL Jerseys ' ' '
