Novak Djokovic came from behind to beat Alexander Zverev 4-6, 6-4, 6-4 in the China Open quarterfinals on October 4. He secured decisive late breaks in the final two sets during the two-hour, 35-minute match. Djokovic extended his unbeaten run from his first appearance at the tournament to 32 matches, surpassing Rafael Nadal's 31-match opening run at Roland Garros. The record concerns starting a particular tournament unbeaten, rather than an entire season.
