Miller becomes a member of one of the World Cup's most exclusive clubs, joining Switzerland's Pirmin Zurbriggen, Luxembourg's Marc Girardelli, Norway's Kjetil Andre Aamodt and Austria's Guenther Mader as the only men to win a slalom, giant slalom, super-G and downhill as well as a combined event.
It was also the third consecutive victory for Miller, who launched his bid to become the first American to win the overall title since Phil Mahre in 1983 by winning the season-opening giant slalom in Austria.
"To move into that group of ski racers who have won four events is the most exclusive club in the world," said Miller, the first man ever to win the opening three World Cup races in different disciplines.

"I've had to battle through criticism, there's been a lot of negative energy because of my persistence to ski four events. It makes it sweet to have that fourth event win.
"I didn't have as high expectations for myself coming into these races. Usually I have pretty high expectations for myself, so it's nice to surprise yourself once in a while."
In another display of aggressive yet controlled skiing, Miller turned in a near-perfect run but had an anxious wait in the finish area for defending overall champion Hermann Maier to barge out of the start hut 16 racers later.
Gritting his teeth, the Austrian Olympic champion charged down the sun-kissed course but once again could not match his American rival's time of one minute 28.18 seconds to complete a frustrating weekend that included a sixth in the downhill.
"Today it was very close but I don't have the confidence right now," said Maier, who finished 0.14 seconds behind Miller. "I have to find the right feeling."
Michael Walchhofer was third, 0.41 seconds further back, but it was still a disappointing weekend in the Canadian Rockies for the Austrians, who had won every race staged at the resort since the events were moved here from Whistler, B.C. in 1999.
The lack of wins will increase the pressure on the Austrian team as the circuit moves to Beaver Creek for four races starting on Thursday.
