Defending champion Daniil Medvedev said missing one key opportunity had cost him a spot in the Shanghai Masters’ fourth round after he was knocked out in straight sets by 26th-ranked Sebastian Korda on Sunday.
The Russian fell apart in the second set after Korda won the first on a tiebreaker taken to the brink, with the match finishing 7-6 (10/8), 6-2.
Earlier, world number nine Casper Ruud continued his smooth progress through the tournament with another straight-sets win, this time against the United States’ Christopher Eubanks.
The Norwegian’s next challenge is Fabian Marozsan, who celebrated his birthday by defeating Serbian Dusan Lajovic in straight sets on Sunday.
Poland’s Hubert Hurkacz is also through to the fourth round.
