final score West Indies (172 for three in 15.5 overs) beat Australia (169 for seven in 20 overs) by 7 wickets Gayle force In the 2007 edition,Chris Gayle plundered a century in the opener against the hosts,but the effort went in vain. Gayle might have fallen short of another three-figure mark on Saturday but did enough to lead West Indies to their first World T20 win. Along with Andre Fletcher,the skipper put on 133 in 69 balls to steer their team to an easy seven-wicket victory over Australia in the tournaments toughest group which also includes Sri Lanka. Gayle smashed six sixes and as many boundaries in his 88 off 50 balls while Fletchers 32-ball 53 included seven hits to the fence as West Indies achieved the 170-run target with more than four overs to spare. Blown away Brett Lee was brutally punished,getting smashed for 27 runs in his third over by Gayle,returning figures of 1 The pair soon brought up their century stand in just 51 balls. By the time Fletcher holed out to a Johnson delivery,the damage had been done. Even as Gayle took the long way back to the pavilion three overs later,Ramnaresh Sarwan and Shivnarine Chanderpaul saw West Indies through. Warner shines Earlier,David Warner led Australia to a defendable total after his team lost Shane Watson and Ricky Ponting in consecutive balls of the first over by Jerome Taylor. Reeling at 3/2,Warner steadily propelled the Australian innings with a 53-ball 63. Warner was out in the 16th over with the total on 113. The Hussey brothers brisk 14-ball 30 partnership took the Australian total past the 150-mark.
