Vijay Singh shot a bogey free round of three-under-par 70 to win the PGA Tour’s season opening Mercedes-Benz Championship at the Plantation Course at Kapalua, Hawaii, by two strokes from Australian Adam Scott. Singh climbs 2 places to World Number 5 while Scott improves his position in the Official World Golf Ranking by one spot to a career best of 3rd.

At its meeting at the 2006 Open Golf Championship the Governing Board for the Official World Golf Ranking approved the following adjustments to the Official World Golf Ranking which became effective from January 1 2007:

1) The minimum points level for the Sunshine Tour in Southern Africa are increased from 12 to 14 points for first place in line with the Asian and Nationwide Tours.

2) The graduated decline of a player's Ranking points over the rolling two-year measurement period are changed so that following an initial 13-week period of full weighting the player's points are reduced on a weekly basis in equal decrements for the remaining 91 weeks of the two year Ranking period. Previously, a player's points were devalued by 1/8th weighting every 13th week over the two year Ranking period. This change is designed to place additional emphasis on current performance whilst at the same time causing a smoother transition of a player's weekly loss of ranking points.
