British number one Cameron Norrie made a winning start at the Auckland Classic and Jack Draper produced a stunning comeback to progress in Adelaide.
Norrie, runner-up last year in the city where he grew up, defeated Frenchman Luca Van Assche 6-3 6-7 (6-8) 6-1.
Draper faced two match points against Miomir Kecmanovic but battled back to earn a 5-7 7-6 (11-9) 7-6 (9-7) win.
Meanwhile, Emma Raducanu withdrew from a second exhibition match days before the Australian Open starts on Sunday.
Raducanu, who pulled out of a charity match in Melbourne on Tuesday, will no longer play 16-year-old Mirra Andreeva at the Kooyong Classic on Thursday as she continues to feel some soreness in her first weeks back on tour.
