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.

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.

Australian concerns about the readiness of their young batsmen to cope with Asian conditions have been underlined by the decision to send Travis Head to Sri Lanka ahead of the dead rubber third Test in Colombo, which starts from August 13.Head was initially omitted from the ODI squad to face Sri Lanka in limited-overs matches, but following Australias heavy defeats in consecutive Tests to surrender the Warne-Muralitharan Trophy, he will now train with the Test squad before remaining as part of the ODI team. This drastic change in plans emphasises the urgent nature of Australian worries about their substandard displays in this series.The coach and selector Darren Lehmann categorically ruled out the possibility of Head taking part in the Colombo Test, but admitted the panel could now see the very real need to give young players as much exposure to Asian conditions as possible. Head must now be considered a strong chance to be taken with the Test squad to go to India next year, provided he can maintain his upward curve of run-making in the Sheffield Shield as captain of South Australia.Well probably look at if there are any players who go home at the end of the Test series, but with Trav, we want him to come in for this prep for this Test, Lehmann said. Hes not going to play. Theres no doubt about that. We see him as a really exciting young player for the future ... give him as much experience around one our Test group, and two our one-day group as we possibly can. Weve been impressed with him. Thats why he has come in a bit early. Hes a young player who has thhe attributes we think are quite important here.dddddddddddd We want to give him as much experience, because hes a young guy who has had some success. He hasnt had enough international exposure and we think its a really good time to do that, with an eye on the future as well.Heads progress as a young player has been watched closely by the selectors for some time, as they are eager to get another young batsman into the Australian side across all formats with the prospect of forging a long career in the manner of Ricky Ponting, Michael Clarke and Steven Smith before him. Earlier this year he was withdrawn from the Australia A side to play a winter series at home in order to allow him to gain greater exposure to English conditions with Yorkshire.Youre always looking at those things, Lehmann said. When you havent had the success youd like, youve got to look at different things. Were really happy with the group. Obviously wed like different results. But we are just bringing him in for the experience more than anything else.Another factor in Heads selection is the desire to familiarise him with the Australian team set-up and players, ideally to form relationships that will help him when he does play. The left-arm spinner Jon Holland had a contrasting experience last week when he was thrust into the Test team without having spent much recent time around the national side, and without any of his Victoria team-mates having made the tour.
