Alina Charaeva, ranked No. 118, achieved a stunning victory over world No. 1 Elena Rybakina at the China Open in Beijing on Saturday, winning 3-6, 6-4, 6-3 after coming back from a set down. This marks the first defeat for Rybakina in her debut match as a top-ranked player, and she joins Naomi Osaka as only the second player to lose her first match at that ranking.

Rybakina, the reigning US Open champion, initially appeared to be in control, taking the first set and leading 2-1 in the second. However, she faced difficulties, losing her serve three times—twice in the second set and once in the third at 3-2. Charaeva capitalized on these errors to secure her place in the last 32 of the tournament.

This match is notable as it marks the lowest-ranked player to defeat a world No. 1 since WTA rankings began in 1975. Charaeva had previously won against Ukrainian Yuliia Starodubtseva in the first round.

Next, Charaeva will compete against Britain's Sonay Kartal.
