Fitzpatrick is the second man to win a US Amateur and US Open on the same course, joining Jack Nicklaus who turned the trick at Pebble Beach. Juli Inkster won the US Women's Amateur and US Women's Open at Prairie Dunes.
Along with the $3.15 million in prize money, Fitzpatrick had that gold Jack Nicklaus medal draped around his neck.
Fitzpatrick, who briefly played at Northwestern before turning pro, won for the eighth time worldwide, and this was his first in America — at least a tournament everyone knows about.
Fitzpatrick said he won the member-member at The Bear's Club in Florida at the start of the year, the course Nicklaus built.
"He gave me a bit of abuse at the start of the year. He said, 'Finally. Congratulations for winning in the States,'" Fitzpatrick said. And then slightly lifting the trophy, Fitzpatrick sent a fun message to Nicklaus: "Jack, I won a second time."
