(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.
"That hasn't changed. I love winning," Woods said Tuesday as he spoke with reporters at the elite 18-man tournament.
"Coming down the stretch on the back nine with a chance to win -- that's the rush, that's the thrill of why we practice.
"That's why we train, why we hit all those balls tireless hours, is to put ourselves in that one position."
Woods has not been in contention much in 2010, with a pair of fourth places in the U.S. Masters and U.S. Open about the highlight.
A year this week, Woods crashed an SUV outside his Florida home and set in chain a series of events which led to a scandal which cost him his marriage and left his reputation sullied.
It also meant a self-imposed five-month break from the golf course, pulling out of the corresponding event at Sherwood Country Club last year as his problems made worldwide headlines.
After he returned at Augusta in April, Woods struggled with swing changes under new coach Sean Foley and was no longer the irresistible force of the past, but he is putting on a brave face.
"As a golfer I learned so much more this year than any other year, and as a person infinitely more," Woods said.
"So it has been a very successful year, even though it was a very painful year, as well."
Woods finished with a 65 in the final round of his latest tournament in Australia and will be hoping for a similar result when the action starts on Thursday.
