Dan Evans and Nick Kyrgios progressed to the round of 16, while top-seeded Casper Ruud lost at the Japan Open on Tuesday.
British No. 2 Evans defeated Moldova’s Radu Albot in three sets, 7-6 (7-3), 6-1, 6-4.
Ruud, who reached the final at both the French Open and the US Open this year, lost to Jaume Munar 6-3, 6-3.
Kyrgios, who lost in the Wimbledon final, defeated Tseng Chun-hsin 6-3, 6-1 to reach the next round. He will next face Kamil Majchrzak, who beat Sho Shimabukuro 7-6 (2), 6-2.
The victory for Kyrgios came on the same day that his lawyer asked an Australian court to dismiss assault charges against him on mental health grounds. Magistrate Glenn Theakston adjourned the case until Feb. 3.
The 27-year-old Kyrgios will appear in court in person on that date for the first time since he was charged by police by summons in July.
The common assault charge, which has a potential maximum sentence of two years in prison, relates to an incident in January 2021 that was reported to local police last December. The charge reportedly relates to an incident involving his former girlfriend.
