René Lacoste won 3 French Open singles titles.
His victories came at the French Championships, the tournament now known as the French Open, in 1925, 1927 and 1929. Lacoste defeated fellow Frenchman Jean Borotra in the 1925 and 1929 finals, and American champion Bill Tilden in the 1927 final.
Lacoste’s three titles were won during the amateur era, before the tournament became an international Grand Slam event in 1925 and before the Open Era began in 1968. He was one of France’s “Four Musketeers,” alongside Jean Borotra, Henri Cochet and Jacques Brugnon. Their dominance helped make French tennis internationally famous.
Three French Open titles were part of Lacoste’s seven Grand Slam singles championships overall. He also won Wimbledon twice and the U.S. National Championships twice. A common mix-up is to count his total major titles rather than his French Open titles: the answer is three for this tournament, seven for his Grand Slam singles career.
