The win helped US Open champion Wawrinka extend his head-to-head lead to 11-2, having now won his last seven matches against Cilic, who is out. Did you know... The last time a player lost his opening match and went on to win the title was in 2009 when Nikolay Davydenko surprised everyone to win at Londons O2 Arena. Shots of the matchWawrinka showed he is not just all about power as he lured Cilic into the net before showing a delicious touch to lob him. Wawrinka showed that hes not all about power with this delicate lob... But when it does come to pure power, Wawrinka can produce it when it most matters - especially on the backhand side. But the Swiss star does possess an awful lot of power on that missile of a backhand... Expert analysisGreg Rusedski: Hes back in business. He played great tonight. Cilic played him into form. Hes very confident going up against Marin because Marin isnt willing to come forward which allowed him to hit many groundstrokes and get a feeling for the ball. By the end of it, he was playing lights out tennis. Its not what Andy Murray wanted to see, an in-form Wawrinka on Friday.Peter Fleming: This match seemed to turn his game around. He was hitting the ball well and hes not going to be an easy guy to put out. Wawrinka joins Leif Shiras at the SkyPad to examine his victory over Cilic The matchThere was very little to choose between the two players, who both packed a punch with some blistering winners. Cilic had made very few inroads into Wawrinkas serve until he earned a set point at 5-4. However, the Swiss star quickly shut the door with a brave 100mph second serve into the body. The Wawrinka backhand was at its blistering best in the second set Quite predictably, it headed into a tiebreak, and it was the third seed who started forcing the errors from Cilics racket, which was enough to take the set.Just when it looked as though Wawrinka had the momentum, Cilic struck in the opening game of the second set. Wawrinka was happy to get his first victory in London after defeating Cilic Despite being hampered by a knee injury recently, the 31-year-old is determined to finish his season on a high, and responded with some fearsome hitting of his own to level in the fourth game.It was enough to send the tight contest into another tiebreaker. And Wawrinka struck a huge blow with an unstoppable 98mph forehand for the mini-break which he never relinquished to set up a mouth-watering clash against Murray.

And while the Edmonton skater earned bronze in the mens 500 metres, he was agonizingly close to standing higher on the podium. Gregg was paired with Tae-Bum Mo of South Korea, this years world champion in the distance. The two men played cat-and-mouse to start the race. Mos opening strides were quicker, but Gregg caught him at 100 metres. Their finish seemed a dead heat, but Mo actually edged Gregg by three thousandths of a second. Ronald Mulder of the Netherlands knocked Mo out of gold-medal position two pairings later in a time of 34.41 seconds. Mos time was 34.52.3 ahead of Greggs 34.52.6. Gregg will race another 500 on Sunday at the Oval and aims for a medal upgrade. "Every World Cup, including this one, in Calgary Ive won a medal so Im happy with that," Gregg said. "Theyve all been bronze so I want to make it a little better than that. Im always getting beat out by the thousandths in Calgary." Greggs bronze was Canadas lone medal on the first day of racing. He lost speed to the South Korean on the turn coming into the home stretch at the Olympic Oval. "You go into the year not really knowing who is going to go fast," Gregg said. "You see some times, but now everyone is at the World Cup and everyone has peaked, so you get to see where you are in the world a little bit. "To know that Im up there with even a less-than-ideal race, it gives me lots of confidence going forward." Sang-Hwa Lee of South Korea won the womens 500 in 39.91 seconds, which was .11 off her world record. Claudia Pechstein of Germany was the winner of the womens 3,000 metres in three minutes 59.04. Koen Verweij of the Netherlands took the mens 1,500 metres in one minute 42.78 seconds ahead of runner-up and world-record holder Shani Davis of the U.S. in 1:43.11. Denny Morrison of Fort St. John, B.C., was the world champion in the 1,500 two years ago, but broke his leg cross-country skiing midway through last season. Morrison says his leg his fully healed, but hes race rusty and finished 11th in a time of 1:44.42. "If you would have talked to me after a race like this in 2009, I would probably hardly have talked to you guys and probably would be freaking out throwing things around the change room," Morrison told reporters. "That doesnt help anything. All I can do is be motivated by what happened and use that to help me focus on what I need to do next. I dont think its discouraging. I know I have a few things to work on. Im pretty sure I can identify what they are already." The Essent ISU World Cup continues Saturday with another womens 500 metres, the mens 1,000 metres and the womens 1,500 metres. Olympic 1,000-metre champion Christine Nesbitt of London, Ont., will race that distance Sunday. The speedskaters can gain Olympic berths for their countries at the 2014 Winter Games in Sochi, Russia, during the first four World Cups of the 2013-14 season.dddddddddddd Canada could take a maximum of 20 skaters to Sochi in February, but has to earn those spots through World Cup results. Nesbitt was 13th and Marsha Hudey of Regina 19th in the womens 500. Winnipegs Brittany Schussler and Ottawas Ivanie Blondin finished 13th and 16th respectively in the womens 3,000. Saskatoons Lucas Makowsky was 17th in the mens 1,500. William Dutton of Regina was 15th in the mens 500. Gregg is the son of former Edmonton Oilers defenceman Randy Gregg and two-time Olympic speed skater Kathy (Vogt) Gregg. His sister Jessica is a short-track speedskater who won Olympic silver in the relay in 2010. Jamie Gregg was eighth in the 500 in 2010. The 28-year-old captured his first World Cup gold medal in 2012 in Berlin. Hes Canadas heir-apparent to Jeremy Wotherspoon in the 500 metres, although Wotherspoon is attempting a comeback and intends to race at Olympic trials this winter. "Ill step into that role," Gregg said. "We have a lot of young guys coming up and Jeremy is also coming back to try and take it back from me so Ive got to fight him off as well. I love the competition. We have some really fast guys." Wotherspoon and Gregg are in-laws, as Gregg is married to Jeremys sister Danielle Wotherspoon. Speed Skating Canada will hold Olympic trials in late December and early January in Calgary, but some countries will choose their Olympic speedskaters based on their results at World Cups. Pechstein says shes qualified for her sixth Winter Games because of her victory in the 3,000. The 41-year-old wants a 10th Olympic medal in Sochi. Shes won five gold, two silver and a pair of bronze in an Olympic career that started in 1992 in Albertville, France. Pechstein did not race in Vancouver. The International Skating Union banned her for two years in 2009 based on irregularities in her blood, although she hadnt tested positive for illegal substances. The most successful German Olympian fought her sanction in both the Court of Arbitration for Sport and in Swiss federal court, but was not allowed to race in Vancouver. Pechstein was the 5,000 metre champion in 2002 and would have competed against Canadas Clara Hughes, the 2006 Olympic champion. Hughes won bronze in Vancouver. Pechstein resumed winning world championship medals in 2011 after serving her suspension. She is currently suing the ISU for loss of income. "When I get a victory, its good for me and I think the ISU doesnt like it," Pechstein said. "Its also good motivation for me. "For me, I can go so relaxed. I never used doping, never used any illegal things. This I know. This is a nice comeback with this today and last season and two years ago too. For me, I can stand up every morning and look in the mirror and Im clear. This is the important thing." ' ' '
