With Tiger Woods forced to sit out this week's Masters tournament for the first time in 20 years, the first major golf championship of the year could produce a new world number one - and it could be an Australian.
The reigning Masters champion Adam Scott, the current world number two, could suprass Woods if he tied for third with no more than one other player, and Jason Day, who hasn't played since February because of a thumb injury, would go top of the rankings with a win at Augusta.
Day has finished second and third in two of his three Masters appearances.
Sweden's world number three Henrik Stenson can also take top spot if he ties for second with no more than one other player.
