20 year old Se Ri Pak defeats amateur Jenny Chuasiriporn, also 20, in a 20-hole playoff for the 53rd U.S. Women's Open and claim her second major championship. This followed victory in the McDonald's LPGA Championship two months earlier, and remarkably they were her first and second LPGA titles in her rookie year on Tour; she has won 21 more events in her career since then, including three more majors, and in 2007 at age 29 she qualified for the World Golf Hall of Fame, becoming the youngest ever living inductee. The Open, held at Blackwolf Run in Kohler, Wisconsin, saw both players tied on 290 after 72 holes, and tied again on 73 after the 18-hole Monday playoff. They shared the first extra playoff hole in par 5s, before Pak finally sealed victory with an 18-foot birdie putt on the 20th. At 92 holes it became the longest ever tournament in women's professional golf.
Max Faulkner wins the Open Championship at Royal Portrush GC in Northern Ireland. It is the only time the Open has been played outside Scotland and England, and it would be another 18 years before a British golfer would win the Claret Jug again - Tony Jacklin in 1969.
Arnaud Massy is born in Biarritz, France. An ex-sardine fisherman and former caddie, in 1907 he won the Open Championship at Hoylake by two shots from J.H. Taylor, becoming the first non-Briton to win the Open. Massy died in 1950, but remains to this day the only Frenchman to have won a major championship, although two have finished second - Jean Van de Velde (1999 Open Championship) and Grégory Havret (2010 US Open).
