CARMEL, Ind. — Dustin Johnson knows as well as anyone that no matter how good he is and how well he plays, something can always go wrong in golf.
Just not this week at the BMW Championship.
Not this year, really.
Johnson ran off four birdies in a five-hole stretch to regain control Sunday, left Paul Casey feeling helpless by matching his eagle putt late in the round and sailed home to 5-under 67 for a three-shot victory at Crooked Stick.
"Ran into a buzz saw," Casey said after 67 to finish runner-up in a FedEx Cup playoff event for the second straight week. "That was something special the last two days, and I did everything I could. So I'm holding my head up very high."
Johnson, though, is at another level right now.
Known for many years as the guy who couldn't catch a break in the biggest events, he won for the third time in eight starts dating to his first major at the U.S. Open. This might have been his most complete performance: powerful off the tee, relentless with the putter, dialed in with his wedges.
"I've got a lot of confidence in every part of my game," Johnson said.
He just doesn't have much to say about it, mainly because he doesn't need to.
Casey's last hope came on the par-5 15th when he rolled in a 25-foot eagle putt to get within one shot. That lasted as long as it took Johnson to line up his 18-foot eagle putt and pour it in to restore his three-shot margin.
He finished at 23-under 265 and went over $9 million in earnings for the year, along with taking the No. 1 seed in the FedEx Cup to the finale in two weeks at East Lake for the Tour Championship.
The consolation for Casey, along with $1,836,000 for his two runner-up finishes, was the No. 5 seed at the Tour Championship. That means he only has to win at East Lake to capture the $10 million bonus.
Rickie Fowler won't have any chance at all.
Fowler, who started the week at No. 22 in the FedEx Cup , closed with 71 and finished 59th. He was bumped out of the top 10 by the smallest margin in the 10-year history of the FedEx Cup — 0.57 points behind Charl Schwartzel, who closed with 64.
The timing is particularly bad for Fowler because Davis Love makes three of his captain's picks for the Ryder Cup today, with another one right after the Tour Championship. Fowler won't have another chance to audition.
