Best Grand Slam runs came in 2023

Her only two Round-of-32 finishes both came in 2023, at the US Open and Wimbledon. That is her best result in the dataset, and it stands out against a career otherwise dominated by Round-of-64 and Round-of-128 exits.

Wimbledon is her most productive major

Wimbledon accounts for 8 of her 22 Grand Slam appearances and all three of her best results. She has reached at least the Round of 64 there in five different years, including both Round-of-32 runs in 2023.

2024-25 brought a stable middle tier

Across 2024 and 2025 she reached the Round of 64 in seven of eight Slam starts, with only one Round-of-128 exit in that span. That is a clear step up in consistency from earlier seasons, even though it did not produce another Round-of-32.

Her Slam record is close to break-even but still negative

She has played 39 Grand Slam matches and won 17, a 44% win rate. The totals show a career that has moved well beyond early exits, but still sits slightly below .500 overall.

She has already reached Grand Slams at age 30

The dataset shows appearances from age 20 in 2017 through age 30 in 2026. Her latest listed result is a Round of 64 at the 2026 US Open, showing she is still active in the draw at 30.
