Novak Djokovic claimed his 102nd ATP Tour title after Alex de Minaur retired early in the second set of the China Open final, SGGP reports. Djokovic won the opening set 7-6, taking the tiebreak 7-3. De Minaur received treatment for a groin problem and stopped after winning the next set's opening game. The result gave Djokovic his seventh Beijing title, with the final decided by retirement rather than the completion of two sets.
