While neither he nor Jordan Spieth played a tournament last week, Jason Day is back at No. 1 as the statistical formula that determines the world golf rankings reboots for a new year.
As the rankings are based on a rolling 52-week calendar of performances, Day’s late-season wins are now in focus compared to Spieth’s early-season successes last year.
Still, the margin between them is microscopic. Day is averaging 12.4235 points per tournament, Spieth 12.3963, a difference of just 0.0272. Rory McIlroy remains No. 3 in the world following his Top 20 finish at the Frys.com Open on Sunday.
The two Sunday winners both enjoyed healthy bumps in the rankings. Emiliano Grillo jumped from 72nd to 36th with his win at the Frys.com Open, and Andy Sullivan went from 66th to 47th for winning the Portugal Masters.
