Daniil Medvedev clinched Russia's spot in the ATP Cup semifinals Wednesday with a 6-2, 6-4 victory against Japan's Kei Nishikori in Melbourne.
The World No. 4 struck nine aces and 19 winners and converted four of six break points. Medvedev, who closed out 2020 with back-to-back titles at the Rolex Paris Masters and Nitto ATP Finals, has a 12-match winning streak.
Earlier in the day, teammate Andrey Rublev rolled to a 6-1, 6-3 win against Yoshihito Nishioka. Japan avoided the sweep with a victory in the doubles match, as Ben McLachlan and Nishioka posted a 4-6, 6-3, 12-10 win against Evgeny Donskoy and Aslan Karatsev.
Italy also advanced to the final four with a victory against France. Fabio Fognini defeated Benoit Paire, 6-1, 7-6 (2), and Matteo Berrettini took down Gael Monfils, 6-4, 6-2. The French won the doubles match, with Nicolas Mahut and Edouard Roger-Vasselin beating Simone Bolelli and Andrea Vavassori, 6-3, 6-4.
The remaining schedule for all events in Melbourne is in question after a worker at one of the quarantine hotels tested positive for COVID-19.
