Who are the youngest players to win a major championship in golf history?
In the history of major championship golf for men and women, there have been fewer than two dozen times that a player who was under 22-and-a-half years wound up hoisting the trophy. There are four majors in the men's game -- the Masters, PGA Championship, US Open and British Open Championship -- and five majors in the women's game -- ANA Inspiration, US Women's Open, KPMG Women's PGA Championship, AIG Women's Open and Amundi Evian Championship. On the men's side, six players under 22-and-a-half years old have won a major, with Johnny McDermott being the youngest in the modern era. He was 19 years, 10 months, 14 days old when he won the 1911 U.S. Open. Young Tom Morris is the outright youngest major winner in history, even though they didn't really exist back in 1868 when he won the Open Championship at 17 years, 5 months, 8 days old. Tiger Woods is the second-youngest major winner in modern men's golf history. He was 21 years, 3 months, 14 days old when he won the 1997 Masters. Lydia Ko is the youngest winner of an LPGA major championship. She won the 2015 Evian Championship at 18 years, 4 months, 20 days to take the mantle from Morgan Pressel, who was 18 years, 10 months, 9 days old when she won the 2007 Kraft Nabisco Championship (now known as the ANA Inspiration).
