Patrick Cantlay has won the BMW Championship after a sudden-death play-off with Bryson DeChambeau.
Both players ended the four rounds on 27 under, with Rory McIlroy back in fourth place on 22 under.
McIlroy recovered after a bogey on the first to card birdies on two and four. The back nine saw four more birdies in a round of 67.
Shane Lowry finished strongly with a round of 65 that included six birdies. His 13-under score saw him in a share of 26th place.
Cantlay held his nerve on the sixth play-off hole for victory.
De Chambeau look poised to win on the 18th, but a monster putt from Cantlay put pressure on a player seeking his third title of the season. De Chambeau missed. With light starting to fade at the Caves Valley Golf Club, it was now sudden-death.
Both had chances to win it in the five holes were subsequently played, before Cantlay holed a ten-footer on the 18th (sixth play-off hole). Pressure then on De Chambeau to hole his six-footer, but it drifted to the right and the title was Cantlay's.
