Due to her ongoing struggles with injuries Radwańska withdrew from the China Open tournament, thus ending the season early with a 14–14 singles record. By the end of the season, Radwańska fell to the 78th position in the ranking – the lowest since 2006, when she made her debut in the WTA series. On 14 November 2018, Radwańska announced her retirement from professional tennis. "Taking into consideration my health and the heavy burdens of professional tennis, I have to concede that I’m not able to push my body to the limits required," she wrote on her Facebook account.
