Novak Djokovic won a record-extending seventh China Open title in Beijing on Tuesday after Alex de Minaur retired at the start of the second set. Djokovic took the opening set 7-6(3) before both players called for medical timeouts. De Minaur returned to win the opening game of the second set but could not continue because of a groin issue. The title was Djokovic's 102nd at tour level and extended his perfect Beijing record to 34-0. He also became the first man in the Open Era to win a tour-level singles title in 21 consecutive seasons.

Carlos Alcaraz defended his Japan Open crown in Tokyo with a 7-6(4), 6-4 victory over Jiri Lehecka. The No. 3 player lost serve in the opening game but rallied from 2-4 down in the first-set tiebreak. He broke in the seventh game of the second set to finish the 96-minute final. It was Alcaraz's first tour-level trophy since Doha in February after missing months with a wrist injury. He is the first man to repeat in Tokyo since Pete Sampras in 1993-94.
