Third-seeded Stefanos Tsitsipas of Greece avenged his loss to Frances Tiafoe at Wimbledon, defeating the American 6-3, 6-4 on Tuesday to advance to the third round of the 2020 Olympics in Tokyo.
Tsitsipas needed just 77 minutes to eliminate Tiafoe in a turnaround from June, when Tiafoe stunned the Greek in straight sets on the opening day of play at Wimbledon. With rain falling outside, the two played under the closed roof at Ariake Coliseum as Tsitsipas struck nine aces and won 28 of 31 points on his first serve.
Next up for Tsitsipas is Ugo Humbert of France, the 14th seed, who came from behind to beat Miomir Kecmanovic of Serbia 4-6, 7-6 (5), 7-5.
In other action, home-crowd favorite Kei Nishikori defeated Marcos Giron of the United States 7-6 (5), 3-6, 6-1. The former world No. 4, Nishikori won the bronze medal in singles in the 2016 Rio Games. He will meet Ilya Ivashka of Belarus, a 6-7 (4), 6-3, 6-3 winner over Mikhail Kukushkin of Kazakhstan.
Other third-round matches will feature Russian Karen Khachanov and eighth-seeded Diego Schwartzman of Argentina, and Jeremy Chardy of France vs. Great Britain's Liam Broady, who upset Hubert Hurkacz of Poland, the seventh seed.
