( CNN ) -- Adam Scott hopes his third Singapore Open title triumph on Monday will act as a springboard for an assault on golf 's four major tournaments next year . The Australian completed a final-round 68 after the tournament went into a fifth day following weather disruptions , finishing on 17-under-par 267 -- three shots clear of Denmark 's second-placed Anders Hansen . The victory , his first at Sentosa since the Asian Tour event became co-sanctioned by the European Tour last year , launched him back into the top-20 of golf 's world rankings . It was the seventh European Tour title of the 30-year-old 's career , and he will now turn his attention to claiming a maiden major title in 2011 . `` You just want your game to be in good shape when you get to Augusta [ the Masters ] or the U.S. Open , the British Open , PGA Championship , '' Scott told the tournament 's website after following up his 2005 and 2006 successes . `` I have n't prepared myself very successfully over the past years , but I sit back at the end of every year and look back at what I 've learnt and how I can do things better . `` If I need to do them differently , I 'll do that in a couple of weeks when the season 's over . '' The Adelaide native reached the top-10 of the rankings in 2005 and the following year achieved his best finish at a major -- tied for third at the U.S. PGA Championship . He spent over 180 weeks among golf 's elite , but his form deteriorated in the following few years and he dropped out of the top-50 in 2009 . Scott was happy with the form he showed in the rain-affected tournament at the Sentosa Golf Club -- his second success of 2010 after winning the PGA Tour 's Valero Texas Open in May -- although he admitted to finding the harsh weather conditions challenging . `` It was a great win but it was a tough week for us . Testing weather conditions with delays and even when we were on the course , it can get uncomfortable at times as it was not easy to play , '' he said . Defending champion Ian Poulter endured a frustrating final round of 73 , slipping to a tie for sixth on 11-under after starting the day only three shots behind Scott . His Ryder Cup teammate Graeme McDowell shot 70 to finish joint third alongside Sweden 's Rikard Karlberg ( 67 ) on 14-under . Spain 's Miguel Angel Jimenez ( 66 ) shared eighth place with Keith Horne of South Africa ( 68 ) , with European Tour money-list leader Martin Kaymer -- the 2010 U.S. PGA champion -- down in 10th after closing with 69 .
Adam Scott wins the Singapore Open for the third time with a total score of 17 under par . Australian won Asian Tour event in 2005 and 2006 before it became co-sanctioned . Scott claims his second title of 2010 as he rises 21 places in world rankings to 20th . Defending champion Ian Poulter fell away to finish the tournament tied for sixth position .
