Suzanne Lenglen
1925: Open French champion

Lenglen returned to tennis at the Beau Site New Year Meeting in Cannes the first week of the year, winning in doubles with Ryan in her only event. She played singles at only two tournaments on the Riviera, including the South of France Championships. Her only loss during this part of the season was to Ryan and Umberto de Morpurgo at the Côte d'Azur Championships in Cannes. In May, Lenglen entered the French Championships, the inaugural edition open to international players. The tournament was played at St. Cloud at the site of the defunct World Hard Court Championships. Lenglen won the triple crown and was not challenged in singles or mixed doubles. She won the singles final over McKane, losing only three games. She won the mixed doubles final with Brugnon against her doubles partner Julie Vlasto and Cochet. Although Lenglen and Vlasto lost the second set of the doubles final 9–11 to McKane and Evelyn Colyer, they won the other two sets with ease for the title.

Lenglen followed her performance at the French Championships with another triple crown at Wimbledon. She played five singles matches and did not lose a game in the second set of any of them. The five games she dropped in total remain a record for fewest games lost in a singles title run in Wimbledon history. Her opponents included Ryan in her opening match, the defending champion McKane in the semifinals, and Joan Fry in the final. In mixed doubles, she partnered with Jean Borotra to defeat Ryan and de Morpurgo in the final. In doubles, Lenglen and Ryan played their last tournament together and won the title without dropping a set. During the last part of the year, Lenglen led France to a 7–4 victory in a tie against Australia, and defeated Australasian champion Daphne Akhurst in the final of the concurrent Deauville tournament. Later in the year, Lenglen won the doubles and mixed doubles events at the Cromer Covered Courts, the only time she played in England other than Wimbledon and her only indoor wood tournament.
