Ian Poulter's sparkling final round 65 in China earns him second WGC title with 'killer instinct' It came about because of a summit meeting with Paul Dunkley and James Dunkley, the father-and-son management team who have been such an influence in his extraordinary rise. Immediately following last month's one-point defeat of the US, Poulter expressed his doubts about taking his Ryder ruthlessness into the much calmer atmosphere of his "day job." But the sit-down with the Dunkleys forced him to try. The $1.2m first prize was emphatic evidence he had been successful. "We talked about how I could convert that "killer instinct" I have in the Ryder Cup and in match play events into stroke play competition," said Poulter, who moved back into the world's top 15. Everyone kept asking me why I couldn't do it, why I didn't have that mindset week-in, week-out. It's about going out there and knowing exactly what have to do, about knowing the course and about being aggressive. I have done exactly that here. I have been very aggressive to targets and converted putts at the right time. I've definitely taken a lot from the Ryder Cup and am obviously riding that wave as much as I possibly can. I need to bottle as much of that confidence to use in stroke play events. It's definitely worked this week. Hopefully it will for a long time. For now Poulter will revel in the continuation of his streak which has featured him winning every season but one in his 13-year career. "This was sorely needed," he said. As well as I've played this year, and as special as the Ryder Cup was, I really would have been disappointed to finish the campaign without a personal victory. This has confirmed to me that I have the game to win majors. That must be the next step for Poulter and when he comes to negotiate it - whether it's at next April's Masters or not - he should remember how he consigned some of the world's best to the shade with his stunning 14-under weekend. Poulter began the final day, four off the pace set by Westwood and Louis Oosthuizen and when Westwood went three clear with two birdies in the first four holes it seemed there would be only one British winner. But Westwood double-bogeyed the par-three fifth, courtesy or an unlucky bounce and a missed tiddler, and from there his putter began to misbehave. Suddenly, the likes of Poulter, Mickelson and Els could sniff the scent. With nine remaining, Westwood was still one clear, but this is where Poulter grabbed the opportunity, birdieing the 11th to claim top spot. From there it was about courage, particularly on the par-five 15th. "That birdie was huge, " said Poulter. I knew it was crucial because Phil was on the hole behind me and with his length it would be easier to make a four. I managed to hole a beautiful 20 foot putt. There was one wobble, when bogeying the 17th. But from the bunker on the last he splashed to eight-feet and anyone who watched Medinah knew what happened next. The putt dropped, a second successive 65 was recorded and win was confirmed on 21-under, with Mickelson, Els and two other Americans in Jason Dufner and Scott Piercy tying for runner-up. Westwood cut a dejected figure in sixth as he signed for a level-par 72, 11 shots worse than Saturday's 61. What he would give for Poulter's short-game. The CV certainly makes impressive reading for a former assistant pro who sold Mars Bars. He had won both versions of the World Match Play - the first WGC title coming in 2010 - but in terms of stroke play this takes him on to a new level. He is up to fourth in the Race To Dubai, but refused to alter his plans to return America to see his children to try to chase down Rory McIlroy at the top of order of merit. With Peter Hanson and Justin Rose not joining McIlroy at the Singapore Open and Hong Kong Open this next fortnight, the young Northern Irishman is almost certain to win both the European and US money lists this season.
