Emma Raducanu and Cameron Norrie were winners on the first day of the Australian Open but Jack Draper struggled with cramp during a four-set loss to Rafael Nadal.
The 21-year-old Draper took the second set against the defending champion before fading in a 7-5 2-6 6-4 6-1 defeat while Raducanu put concerns over an ankle injury behind her to set up a clash with Coco Gauff.
