Jon Rahm defeated Dustin Johnson on the first hole of a playoff in a dramatic climax to the BMW championship at Olympia Fields in Illinois, Chicago.
Spaniard Rahm, 25, appeared to be crowned champion after a bogey-free six-under-64 left him on four-under.
But Johnson, who won by 11 shots last week, puckered the 14th and then pitted a 43 feet by 18 pit to force additional holes.
Rahm then drilled an even longer putt on the same green in the playoff while the American's attempt ended too short.
Rahm came from three shots behind that started the day after Johnson tied the lead while Japan's Hideki Matsuyama entered Sunday's round.
But Rahm birdied back-to-back at 3pm and 4pm in a scintillating round to set the clubhouse goal.
The Ryder Cup player who only dropped a shot over the weekend was given a one stroke penalty for picking up his ball without having marked it on Saturday.
Chilean Joaquin Niemann and Matsuyama finished one more battle back at two under par on the North Course at Olympia Fields in Chicago.
England's Matthew Fitzpatrick ended the weekend with four shots off the lead after a final day 67.
The top 30 players in the points table have qualified for the season-ending Tour Championship at East Lake, Atlanta, which starts next week.
Tiger Woods, who needed a finish in the top five, is one of those to be missed.
