PACIFIC PALISADES, Calif. -- Tiger Woods returns this week to Riviera Country Club, site of his first PGA Tour appearance as an amateur 27 years ago and the place closest to his boyhood home in Southern California. The iconic venue also has yielded a surprising amount of frustration for the 80-time PGA Tour winner. Now known as the Genesis Open, Woods has 12 appearances in the event without a victory -- the most of any tournament that he has not won, surpassing nine visits to the Northern Trust (played at various courses) and five to the Honda Classic.
