Kiki Bertens

Insights

Peak came in 2016, with a semifinal run at Roland Garros

Bertens’ only semifinal is the 2016 French Open, and it is also her best Grand Slam result overall. That season stands out as her deepest major campaign by a clear margin.

Wimbledon 2018 was her only quarterfinal and her best non-Roland Garros result

Her second-best Grand Slam finish is the 2018 Wimbledon quarterfinal, the only time she reached the last eight. No other major outside Paris went beyond the round of 32.

She was most productive at age 26-28

Her strongest stretch runs from age 26 to 28: in 2018 she reached a quarterfinal and three round-of-32s, and in 2020 she made two round-of-16s. By age 29 in 2021, both majors ended in the first round.

Her career ended with a sharp drop after 2020

After reaching the round of 16 at both the Australian Open and French Open in 2020, she lost in the first round at Wimbledon and the French Open in 2021. That is a clear two-year decline from second-week contention to R128 exits.

Clay was her best surface by results, but not by volume

Her deepest runs came at the French Open: one semifinal, one round of 16, and one round of 32. Across 34 Grand Slam tournaments, that clay success contrasts with mostly early exits elsewhere.
