Lacoste won the U.S. Women's Open in 1967 as a 22-year-old amateur, playing in just her third professional golf tournament. She was only the second non-American to win an LPGA major after Fay Crocker of Uruguay (whose father was American), and she remained the only Frenchwoman to do so until Patricia Meunier-Lebouc won the 2003 Kraft Nabisco Championship. To date, she remains the only amateur to win the U.S. Women's Open.
In 1968 Lacoste won the Women's Western Amateur. In 1969, Lacoste also won both the U.S. Women's Amateur and British Ladies Amateur, but she never turned professional. Lacoste was a member of the French team that won the inaugural Espirito Santo Trophy in 1964. She was part of her country's team again in 1966, 1968, 1970, 1974, 1976, and 1978.
Lacoste is the daughter of French tennis player René Lacoste and his wife Simone de la Chaume, winner of the 1927 British Ladies Amateur. She sits on the board of Lacoste, the major fashion company founded by her father. She has been president of the Chantaco Golf Club, founded by her grandfather René Thion de la Chaume in Saint-Jean-de-Luz, near her home, for many years. She married Jaime Prado y Colón de Carvajal; the couple had four children. She also has a home in Spain. She has played little tournament golf for many years, but serves as non-playing captain of the French women's amateur team. She is now married to Angel Piñero, who is a classical guitar player.
