Karatsev won 6-3, 6-3 over Andy Murray
in the final of Sydney on Saturday.
Karatsev overpowered the British wildcard as he smashed 29 winners across one hour and 32 minutes to claim the third title of his career in impressive fashion. The 28-year-old Russian improves to 3-1 in finals in his career, with all of those matches coming in the last year. Karatsev, the No. 18 seed at the upcoming Australian Open, could face No. 10 seed Hubert Hurkacz
in Round 3.
