(CNN) -- Tiger Woods has one last chance to salvage a victory from a sorry 2010 and claim back his World No.1 spot from England's Lee Westwood.
Woods is the tournament host this week at the Chevron World Challenge in California, which is not an official PGA Tour event but does count towards the world rankings.
If the American wins and Westwood finishes outside the top two in the Nedbank Golf Challenge in South Africa, Woods will go back to the top.
But it will be a fleeting success as Westwood is certain to go into 2011 as No.1 as Woods will lose some of the points he accumulated over the past two years by the end of the year.
But for Woods it will be a win that will be his primary motivation. CNN
