As a fourteen year old, Clijsters could only enter professional tournaments through qualifying since the WTA Tour's policy did not allow players her age to receive main draw wild cards. In August 1997, Clijsters qualified for her first main draw at her second career tournament on the lower-level ITF Women's Circuit, which was held in the Belgian coastal town of Koksijde. She won seven matches in total, including five in qualifying, to reach the quarterfinals. Clijsters did not enter another professional tournament until after her runner-up finish at the Wimbledon girls' singles event the following summer. Playing in Brussels in July 1998, she won both the singles and doubles events for her first career professional titles. Clijsters continued to excel at the ITF level, winning four more titles within the next year, two in both singles and doubles.
