Sweden's David Lingmerth beat England's Justin Rose in a play-off as Tiger Woods finished last of those who made the cut in the Memorial Tournament.
Lingmerth, 27, won at the third extra hole after carding a three-under-par 69 to finish 15-under in his final round.
Rose, 34, held a three-shot lead going into the final round, but bogeyed four of the opening eight holes.
He recovered on the back nine, carded a 72 and forced a play-off with a par on the last at Muirfield Village, Ohio.
While Rose struggled at the start of his round, Lingmerth birdied two of the opening three holes and belied his world ranking of 212 to birdie three more in the back nine without dropping a shot.
Both players rolled in curling par putts on the first hole in the play-off and after two more pars on the next, Lingmerth holed a five-footer to take his first PGA tour title at the next as darkness descended.
Woods carded a 74 after the worst round of his career on Saturday in Ohio.
The former world number one was 14-over for the tournament and finished 29 strokes behind the leaders and eight behind the rest of the field.

Woods, 39, had recorded a 13-over 85 in Saturday's third round to start from last place for the first time in his career in the final round.
He appeared to be bouncing back from his third-round nightmare as he reached the turn in three-under for the round, and then birdied the 11th before his game fell to pieces in the final six holes.
Woods double-bogeyed the 15th and 18th holes, and also suffered bogeys at the 13th and 17th.
He said: "Today was a lot better ball striking-wise but I didn't finish off very good."
