Playing style

Clijsters is recognized for her deep, powerful, well-placed groundstrokes. She can hit outright winners off both wings and from any part of the court. Her forehand is one of the best and most powerful the women's game has ever seen, yet occasionally erratic and prone to unforced errors; her backhand is more reliable and consistent, and can be hit with heavy slice as a defensive shot. Clijsters is also recognised for her all-court defence, characterized by speed and athleticism. Clijsters, along with Jelena Janković

, said, "You just have to expect that she's going to get every ball back". Her first serve, while not overwhelming, is placed well and earns aces and unreturnables. Clijsters tends to rush between first and second serves, which may contribute to her occasional matches with high numbers of double faults. A former World No. 1 player in doubles, Clijsters has exceptional volleys; she has no problem switching from baseline to finishing points at the net with a volley or over-head. Her mental fragility was considered her biggest weakness, and at the earlier stages of her career she was considered a "choker", often surrendering big leads in the latter rounds of Grand Slams.
