AUGUSTA, Ga. – Even another Masters victory might not be enough for Jordan Spieth to wrest control of the No. 1 ranking.
Only one scenario exists this week for Spieth to return to the top spot, according to Golf Channel world-rankings guru Alan Robison: Spieth must defend his title at Augusta and Jason Day has to finish worse than a two-way tie for fifth.
In other words, Day will remain at No. 1 if he finishes no worse than a two-way tie for fifth, no matter how Spieth plays. Only three players have won back-to-back Masters titles.
Rory McIlroy cannot rise to No. 1, even if he completes the career Grand Slam with a Masters victory.
