Tiger Woods moves up rankings

Behind his dramatic 1-shot victory at the Chevron World Challenge on Sunday, Tiger Woods soared in the Official World Golf Rankings to No. 21 after nearly three months spent outside the top 50.

The silly-season event, with only 18 players in the field, began awarding world ranking points in 2009.

Woods dropped as low as 58th on Nov. 6, 2011 and hasn't been inside the top 20 since mid-July. He's expected to continue to climb in 2012 since the two-year rolling scale used by the rankings will be taking off his 2010 performances now, instead of victories earned earlier in 2009.

At one point during his drop earlier this year, Woods went down in the world rankings for 15 consecutive weeks.

Woods has not been No. 1 in the world since Lee Westwood took over the spot on Halloween in 2010.
