Rafael Nadal avoided meeting a seed first up at his comeback tournament after drawing a qualifier in the Brisbane International, with Russia's Aslan Karatsev a potential second-round opponent

Nick Kyrgios and former world number one Andy Murray will play in the Sydney Tennis Classic, which begins on January 10, ahead of the Australian Open.

Australian Open: Aslan Karatsev beat Grigor Dimitrov 2-6, 6-4, 6-1, 6-2 to reach the semi-final in his maiden Grand Slam.

Australian Open: Andrey Rublev ensured Grand Slam history will be made for Russia after setting up an Australian Open quarter-final against compatriot Daniil Medvedev on Monday.

Aslan Karatsev powered 50 winners, including nine aces, past the shell-shocked Diego Schwartzman who could muster only five of his own in return in a 1hr 52min drubbing.
