There were top ten finishes for Thorbjørn Olesen and Charl Schwartzel as Japan's Hideki Matsuyama won the Memorial Tournament in a play-off with Kevin Na after a dramatic final day at Muirfield Village.
Na was in early at 13 under after a superb eight under par 64 and waited for around 90 minutes while the other leading challengers fell apart on the closing stretch.
Overnight leader Bubba Watson dropped out of contention altogether after shedding three shots on the 14th and 15th holes of the Jack Nicklaus-designed course.
Matsuyama almost followed, requiring birdie at the last - after breaking his driver - to finish alongside Na and force a play-off.
Both players made a mess of the extra hole, with Matsuyama's tee-shot - with a wood - finding sand before Na drove into the creek on the left of the fairway.
Na then missed right while Matsuyama struck a spectator on the other side, but the Japanese player produced a superb flop on and holed out for par and victory.
Earlier, Na came from off the pace with the help of birdies at all four par fives in a tremendous bogey-free round.
World Number One Adam Scott shared fourth place with Chris Kirk, having gone out in 32 but come home in 39.
South African Schwartzel finished in a group at eight under and produced arguably the shot of the day, holing an outlandish flop from creekside rough at the 11th for birdie.
Olesen was on the same mark, while England's Paul Casey was seven under and Northern Ireland's Rory McIlroy a further shot back after finishing an eventful tournament with a level par 72.
