With his fourth win in six events, Jason Day took over the spot for the first time in his career. He's the 19th golfer to hold the spot and the third Australian (Greg Norman and Adam Scott).
Day rolled through the BMW Championship at Conway Farms with a six-stroke win over Daniel Berger. He cruised on the weekend after shooting 61-63 the first two days to tie the lowest 36-hole score in PGA Tour history.
It pretty easy on Sunday as Day shot his second-straight 69 with birdies on two of the last three holes to get the six-stroke win. It was the second wire-to-wire win on the season (Jordan Spieth did it at Augusta).
McIlroy finished third in the field in strokes gained tee to green and 48th in strokes gained putting. That's become a too-common theme for him over the last few months. Still, he moved up enough (to No. 11) that he's in a good position to take down the FedEx Cup if he plays well at East Lake next weekend.
