Jordan Spieth failed to win the PGA Championship on Sunday, but he moved to No. 1 in the Official World Golf Ranking.
Spieth, who had a remarkable run in the majors that saw him win the Masters and U.S. Open and miss a playoff by one stroke at The Open, finished three strokes back of PGA Championship winner Jason Day.
The solo second-place finish coupled with Rory McIlroy's 17th-place finish meant a new No. 1 for the first time in more than a year.
At 22, Spieth becomes the second-youngest No. 1. Tiger Woods was 21 when he went to No. 1 in 1997.
Spieth has earned over $10 million this year and collected a cool $1.1 million with Sunday's second-place finish.
Spieth needed at worst a two-way tie for second if McIlroy was worse than a three-way tie for 13th.
"The way Jordan has been playing and the way I haven't played much this year ... if he goes to No. 1 today, it's very deservedly so," said McIlroy, who shot a final-round 69 and finished some 90 minutes before the final group. "Winning two majors, winning a couple other times this year, had a chance at The Open, has a chance obviously today...
"And if he was to get to No. 1 today, I'd be the first one to congratulate him because I know the golf you have to play to get to that spot, and it has been impressive this year."
