Janzen, who had been fighting off a bad head cold all week, was victorious in the trouble shot challenge and the putting challenge. He finished second in the bunker shot challenge and the chip shot challenge.
For his efforts, the 36-year-old from Orlando, Fla. received a record first-place prize of $233,500 from the total purse of $1 million.
David Duval also won two categories and finished in outright second place. PGA Tour rookie Gary Nicklaus claimed third.
Said Janzen: 'Sometimes when you're not feeling well you tend to concentrate better and play better.'
