American Collin Morikawa emerged from a stacked leaderboard to win the 2020 US PGA Championship after a flawless final round in San Francisco.
At one point on the back nine, six players shared the lead but an eagle on the 16th saw the 23-year-old go clear.
The world number 12 carded a six-under 64 at TPC Harding Park to reach 13 under in just his second major.
England's Paul Casey was two shots back in a tie for second with overnight leader Dustin Johnson after a 66.
Like Morikawa, Matthew Wolff was another unheralded American to rise through the field on Sunday, shooting a 65 to finish on 10 under.
He tied for fourth with Jason Day, Bryson DeChambeau and Tony Finau, who all carded 66s on a nail-biting final day which made a mockery of concerns over how competitive the year's first major would be with no fans.
England's Justin Rose carded a 67 to finish a shot further back after being three behind the lead overnight, along with compatriot Tommy Fleetwood, who slipped to three under.
Two-time defending champion Brooks Koepka trailed Johnson by two heading into the final round yet stumbled to a four-over 74 to also finish on three under.
