Choi won Jack Nicklaus's Memorial Tournament in 2007. He mentioned on CBS during the AT&T National that he read Jack Nicklaus's "Golf My Way" book early in his golf career, which assisted him in becoming the golfer he is today.
Choi won the first AT&T National hosted by Tiger Woods at the Congressional Country Club in Bethesda, Maryland. The trophy is a small replica of the United States Capitol building in Washington, DC. He made a spectacular sand trap shot on the 17th hole for a birdie to clinch the win over Steve Stricker by 3 shots. Choi was a crowd favorite and threw his golf ball into the crowd after holing his sand shot on the 17th hole.
Choi represented South Korea in the WGC-World Cup in 2002, 2003 and 2005, and was a member of the International Team in the Presidents Cup in 2003 and 2007. In August 2007 he reached the top 10 of the Official World Golf Rankings for the first time. In January 2008, Choi won the Sony Open in Hawaii and rose to world number 7. In March 2008, Choi reached fifth place in the rankings. He has spent over 20 weeks in the top-10 of the rankings.
Before picking up golf Choi was a competitive power lifter, being able to squat 350 pounds as a 95 pound 13 year-old teenager, thus aptly nicknamed "Tank" by South Koreans.
After his 7th PGA Tour victory at the 2008 Sony Open in Hawaii, Choi donated $320,000 of his earnings to the victims' families of a warehouse fire in Seoul, South Korea, which killed over forty people.
