As of 2019, which tennis player holds the record for the fewest games lost in a singles Wimbledon tournament?

Suzanne Rachel Flore Lenglen (24 May 1899 – 4 July 1938) was a French tennis player. She was one of tennis's biggest stars in the 1920s, building her popularity off of her status as the youngest major champion in tennis history as well as her elegant style of play and exuberant personality. Often playing in front of sell-out crowds and appearing on the front pages of newspapers for her biggest matches, she is often regarded as the first female athlete to become a global sport celebrity. Lenglen was ranked No. 1 in the world from 1921 through 1926, winning 8 Grand Slam singles titles and 21 in total. She also won 10 World Championship titles across all disciplines.

In 1925 Lenglen won the Women's singles title 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.
