Rory McIlroy has consolidated his lead atop the world rankings with his second straight win on the USPGA Tour on Sunday, while Tiger Woods has gone back to second as his main challenger. In so doing he became the first player since Woods in 2009 to win in successive weeks on the US tour and he joined Woods and Jack Nicklaus as the only players to win at least six PGA Tour events before his 24th birthday. He also stormed ahead in the world rankings with 12.80 points, with Woods overtaking Donald on 9.63 points. Donald drops to third with 9.17 points with another former No.1, Lee Westwood of England, in fourth on 7.57 points. Woods, third and fourth in the last fortnight, lost his world No.1 spot to Westwood in November 2010 and with injury dogging him last year, he subsequently slumped out of the top 50 before beginning his recovery in the summer.
