Insights

Six titles, all in a four-year peak

Her six Grand Slam championships came in 1946, 1947, 1948, 1949, and 1950, with multiple wins in 1949 and 1950. That means every title in the data was captured within a five-season span.

Wimbledon was the most volatile major

Wimbledon produced one title, two finals, one semifinal, and three quarterfinal exits. Across seven Wimbledon appearances, she reached at least the semifinal stage four times but never repeated the title after 1947.

US Open was her most productive event

The US Open accounts for three of her six titles, plus one final and two quarterfinals. No other Slam in the data matches that combination of repeated championships and deep runs.

Late-career results stayed elite into her 30s

Her last title came at age 32 in 1950, and she still reached the French Open semifinal at 33 in 1951. Even at 38 and 40, she was still appearing in Grand Slam quarterfinals at the US Open and Wimbledon.

French Open shows the widest spread of outcomes

At the French Open she won twice, reached one semifinal, and also had one quarterfinal exit. That mix of results across 1946, 1947, 1949, 1950, and 1951 shows a broader range than any single-event pattern elsewhere in her record.
