The revolving door atop the Official World Golf Rankings keeps spinning.
After returning to world No. 1 this week without hitting a shot, Brooks Koepka went to the Dunlop Phoenix in Japan needing to play well to protect his ranking. Because of the metrics by which the rankings are calculated, Koepka needed to finish in a two-way tie for 11th to keep an idle Justin Rose from moving back to No. 1.
Instead he finished alone in 12th, leaving the rankings in a near dead heat: Rose is projected to move to No. 1 in the next update with a 10.
