Rory McIlroy was pipped to the BMW Championship title in St Louis by Wyndham Clark after his final-round fightback fell short.
The back-to-back Masters champion started the final round five shots behind overnight leader Clark but was level after 15 holes.
But while McIlroy bogeyed the 17th, Clark maintained his composure to birdie the 16th, 17th and 18th holes to wrest back control.
The two-time US Open champion ended the tournament three shots clear of Patrick Cantlay, who edged McIlroy for second.
It moves Clark up to third in the FedExCup Rankings after won his third PGA Tour title of the season.
McIlroy had multiple chances to take the lead but he was not able to take them, ultimately making a bogey six on hole 17 to end his challenge.
