Kim Clijsters

Insights

Four titles, four runner-up finishes, four semifinal runs

Clijsters’ Grand Slam résumé is unusually balanced at the top: 4 championships, 4 finals lost, and 8 semifinal appearances. That means 16 of her 36 Slam tournaments ended in at least the last four.

Peak years clustered between 2003 and 2011

Her four titles came in 2005, 2009, and 2011, while her four finals also include 2001, 2003, and 2004. Across that span she repeatedly reached the decisive rounds, with semifinal runs also appearing in 2002, 2003, 2006, 2007, and 2012.

Best Slam was the US Open

The US Open produced two of her four titles, plus one final, one semifinal, one quarterfinal, one round-of-16, one round-of-32, one round-of-64, and one round-of-128 result. No other Slam matches that breadth of deep runs and titles in the data.

Late-career comeback still reached the top four

After her 2009 return, she won the 2009 US Open at age 26 and the 2011 Australian Open at 27, then reached the 2012 Australian Open semifinal at 28. Her final recorded Slam appearance was the 2020 US Open at age 37, ending in R128.

Early breakthrough came before age 20

By age 16 she had already reached the Wimbledon round of 16 and the US Open round of 32 in 1999. At 17 she added a French Open round of 128, a Wimbledon round of 64, a US Open round of 64, and a French Open final at 17.
