Jordan Spieth became the 18th man to be ranked No. 1 in the Official World Golf Rankings, taking the spot from Rory McIlroy following Spieth’s second-place finish at the PGA Championship on Sunday.
At age 22 years, 21 days, Spieth is the second-youngest man to attain the No. 1 ranking. Only Tiger Woods achieved the ranking at a younger age – 21 years, 5 months, 17 days, in June of 1997.
McIlroy, the man Spieth supplanted after 54 weeks atop the rankings, first became ranked No. 1 at 22 years, 10 months, 1 day of age.
Spieth is averaging 12.4743 points, McIlroy 12.2481.
PGA champion Jason Day jumped two spots from fifth to third with his first Major, and Justin Rose, who finished fourth, climbed to No. 5. Third-place finisher Branden Grace vaulted from 28th to 20th and has risen 62 spots since the start of the 2015 season.
Another missed cut meant another slide in the rankings for Tiger Woods, who fell to 285th from 278th, and will likely drop out of the top 300 in the weeks ahead.
