Who is the youngest golfer to win a PGA Tour event?

John McDermott was the youngest golfer to win a PGA Tour event. He won the 1911 U.S. Open at 19 years, 10 months and 14 days, a record that remains part of the Tour’s historical youngest-winners list.

McDermott defeated George Simpson and Mike Brady in an 18-hole playoff at Chicago Golf Club after the three players tied after 72 holes. His victory made him the first United States-born golfer to win the U.S. Open, which had previously been dominated by players born in Britain and Ireland.

The record can be surprising because the PGA Tour did not yet exist as an independent organization in 1911. Modern PGA Tour records retrospectively recognize many early professional championships, including the U.S. Open, as PGA Tour victories. McDermott also won the U.S. Open again in 1912, becoming the first player to successfully defend the title.
