Wimbledon was her clear peak

Her best Grand Slam result was a semifinal at Wimbledon in 1983, and Wimbledon also produced her other top runs: R32 in 1978, 1977, and 1982, plus R64 in 1981 and R128 in 1976, 1979, 1980, and 1986.

1983 was her strongest season by far

In 1983 she reached the Wimbledon semifinal, while also making the Australian Open and US Open round of 64. That was her only season with three results at R64 or better and the only year she paired a major breakthrough with two additional solid runs.

Her best French Open stretch came in the early 1980s

The French Open was where she reached her deepest non-Wimbledon runs: R16 in 1977 and again in 1982, plus R32 in 1981. Across the rest of her French Open appearances, she was mostly at R64 or R128.

She stayed competitive for a long span, but the late years faded

Her Grand Slam career ran from 1975 to 1986, spanning 33 tournaments and 70 matches. After reaching R32 or better in 1984, her final two seasons were limited to R64 and R128 results, including three straight R128 exits in 1986.

Her overall record was slightly above break-even

She finished with a 37-33 Grand Slam match record, a 53% win rate, across 70 matches. That total is built on 33 tournaments and reflects a career with more wins than losses, but not by a wide margin.
