Nick Kyrgios has guaranteed himself some Australian Open practice with a debut appearance at the Hopman Cup in Perth. After being a late scratching last year with a back injury, Kyrgios (left) has been confirmed to lead the Australia Green outfit as two local pairings feature in the mixed teams' exhibition tournament for the first time in 30 years. Retiring champion Lleyton Hewitt and Casey Dellacqua will form the Australia Gold team, with officials yet to find a partner for Kyrgios for the   January 3-9 Open warm-up event. With the threat of a 28-day suspension from the ATP Tour hanging over his head, Kyrgios would be banned from official Open lead-up tournaments in Brisbane, Chennai, Doha, Auckland and Sydney if he accrues fines totalling $US3500 ($A4820) in his final two outings of 2015 in Valencia and Paris. But now he is assured of at least three singles and doubles matches in a solid start to the Australian summer. The Hopman Cup has also attracted big names in world No.2 Andy Murray, Frenchman Gael Monfils and Serena Williams. "I didn't get to play this year so I'm really looking forward to just being healthy and getting out there," Kyrgios said.
