McIlroy strengthens lead in the world rankings

World No. 1 Rory McIlroy closed his season in style as he birdied the final five holes to come from behind and win on Sunday in Dubai and that helped him increase his lead in this week's world rankings.

McIlroy's lead atop the rankings went from 3.53 average points to 4.33.

Luke Donald shared third behind McIlroy, but still lost ground in the rankings. Donald was again followed by Tiger Woods, who will host his World Challenge starting on Thursday.

Justin Rose took second behind McIlroy and moved up three spots to No. 4 in the latest rankings. Adam Scott remained in fifth, while Lee Westwood was down two to six and Louis Oosthuizen dropped one to seventh.

Jason Dufner held steady at No. 8 and was followed by Webb Simpson, Brandt Snedeker and Bubba Watson. Ian Poulter and Phil Mickelson exchanged spots with Poulter up to 12th.

Steve Stricker, Keegan Bradley and Nick Watney remained in the 14th to 16th positions. Peter Hanson jumped two to 17, which bumped Matt Kuchar and Dustin Johnson down a spot apiece to 18 and 19. Ernie Els was 20th again this week.
