Graeme Storm of England fired a hole-in-one in his third round 6-under 64 to lead the European Masters on Saturday.
Storm's 16-under total of 194 was one stroke clear of Englishman Tommy Fleetwood, who shot 63 on the sunbathed, 6,848-yard (6,262-meter) Severiano Ballesteros course.
Using a 6-iron in thin Swiss Alps air, Storm aced the 217-yard (198-meter) par-3 11th to win a car worth $186,000.
Brooks Koepka of the United States trailed Storm by two after making double-bogey on the par-4 18th, his only dropped shots in a 66.
Another American, David Lipsky, shot 66 to be three strokes off the lead in fourth.
Ryder Cup rookie Jamie Donaldson of Wales was a further stroke back, losing the lead after triple- and double-bogeys on par-4s coming home.
