Janzen was born in Austin, Minnesota, and spent most of his childhood in Baltimore, Maryland, where he played Little Leaguebaseball.[2] When Janzen was 12, his father's company transferred him to Florida and his parents started him in golf and tennis, and he continued playing baseball. Janzen liked golf best and started playing that sport exclusively. He won his first tournament at age 15 as a member of the Greater Tampa Junior Golf Association.[2]
In 1989, Janzen joined the PGA Tour.[3] He has won eight times on the PGA Tour, most notably the 1993 and 1998 U.S. Opens. In 1993, Janzen defeated Payne Stewart at Baltusrol in Springfield, New Jersey, en route to tying the 72-hole U.S. Open scoring record of 8-under-par. Five years later, he again beat out Stewart to win his second U.S. Open, this time at the Olympic Club in San Francisco. He overcame a five stroke deficit on Sunday, marking the best final-round comeback in a U.S. Open for 25 years since Johnny Miller's win in 1973.[4]
Janzen also notched a victory at The Players Championship in 1995. The Players is a premiere event on the PGA Tour and includes the largest purse of the season. He has been featured in the top 20 of the Official World Golf Ranking.
Janzen had several opportunities to win additional major golf championships. In 1996, he was in contention at both the U.S. Open and PGA Championship before finishing in the top-10 in both events. He finished fourth at the 1997 PGA Championship after sharing the 36-hole lead at Winged Foot in Mamaroneck, New York.
Janzen also played on two American Ryder Cup teams, in 1993 and 1997.
