Three players at the Masters have a chance to replace Tiger Woods as No. 1 in the world.
Masters champion Adam Scott, who squandered a great shot at being No. 1 when he lost a three-shot lead at Bay Hill, would need to finish in a two-way tie for third this week at Augusta National.
Henrik Stenson (No. 3) would need at least a two-way tie for second at the Masters to become the first Swedish play at No. 1 in the world.
Jason Day (No. 4) would have to win the Masters to have any shot at being No. 1.
Woods is not playing the Masters for the first time in his career because of back surgery that will keep him out of golf until the summer.
