Jason Day Becomes World No. 1 for First Time Following BMW Victory
After winning his first career major at the PGA Championship last month, Jason Day has now crossed another career goal off his bucket list, becoming the World No. 1.
Day's 6-stroke victory at the BMW Championship this weekend vaulted the 27-year-old Australian from third in the ranking to the top spot for the first time in his career. He is the youngest Australian to ever hold the number one spot, joining Greg Norman and Adam Scott as fellow countrymen to be ranked No. 1.
It was Day’s fifth victory of his 2015 season. Four of them have come since the beginning of July, which means they retain their full value now while Jordan Spieth and Rory McIlroy’s respective victories from spring have progressively lost value in the ranking system. As of this week, Day’s world ranking average sits at 12.64, but his two predecessors at No. 1 still remain less than a full point behind.
McIlroy and Spieth entered last weekend as the top-two golfers in the world, separated by the narrowest margin that Nos. 1 and 2 have ever been. After they both finished in the top 15 Sunday, very little has changed as McIlroy still has a slim edge (.03 points) over Spieth.
With just one tournament remaining on the PGA Tour schedule, the Tour Championship at East Lake is the last significant strength event for the next month. With three players stuck in proximity to each other, next week may very well bring another player to the top of the ranking.
