Peak came at the 1980 US Open quarterfinal

Her best Grand Slam result was a quarterfinal at the 1980 US Open, reached at age 23. That stands out as her only result beyond the round of 16 across 17 tournaments and 36 matches.

Most of her Slam career clustered in the early 1980s

Hallquist played 11 of her 17 Grand Slam tournaments from 1981 to 1983. Those three seasons also produced 22 of her 36 matches, showing that most of her Slam volume came late in the career span listed here.

Wimbledon and the US Open were her most frequent stages

She appeared at Wimbledon six times and the US Open nine times, compared with only one Australian Open and one French Open showing in the data. Her best Wimbledon result was R32 in 1978, while her best US Open result was the 1980 quarterfinal.

Her results were strongest at age 23

At 23 in 1980, she produced both her deepest run and her second-best run: Q at the US Open and R16 at the Australian Open. No other age in the table matches that combination of depth and breadth.

She finished with a sharp drop after a steady middle stretch

From 1977 through 1982, every Slam result was R64 or better except the 1982 French Open R128. In 1983, however, she opened with R64 at Wimbledon and then fell to R128 at the US Open, her weakest listed finish.
