US golfer Tiger Woods watches his approach shot to the 18th hole on the final day of the Chevron World Challenge at Sherwood Country Club in Thousand Oaks, California, on December 4, 2011.  Woods won the Chevron World Challenge on a one-shot triumph in an unofficial 18-man event, his first victory since a 2009 sex scandal shattered his iconic image. Woods had gone 26 starts worldwide without a victory as personal turmoil was followed by struggles on the course with swing changes and, this year, injuries that curtailed his playing time and stalled his pursuit of Jack Nicklaus' record of 18 major titles at 14.
