Beginning in 2009, the Diamond Games in Antwerp was reorganized from a WTA tournament into an exhibition series. During her comeback, Clijsters played at the event three times, winning matches against Venus Williams in 2009, Henin in 2010, and world No. 1 Caroline Wozniacki in 2011. She continued to play at the event after retiring. The 2012 edition was named "Kim's Thank You Games" in honor of her retirement, and the following year the event was known as the Kim Clijsters Invitational. In 2015, the Diamond Games were revived as a WTA event with Clijsters serving as the tournament director. She also played an exhibition set with finalist Andrea Petkovic after her opponent withdrew before the start of the championship match due to injury.
