Australian Nick Kyrgios warmed up for a meeting with Andy Murray by recording an opening-day win in the Hopman Cup.
Kyrgios, fined £16,200 for remarks about Stan Wawrinka's girlfriend in August, beat German Alexander Zverev in the mixed teams event in Perth.
The 20-year-old faces world number two Murray when Australia Green, one of two teams representing the host nation, play Great Britain on Wednesday.
"I have been looking forward to that for a long time," he said.
"I'm going to go and do everything I can to physically prepare for that battle.
