Highlights of the fourth day at the Australian Open, the first Grand Slam tournament of the year, on Wednesday (times AEST; GMT+11): 1100 PLAY DELAYED BY RAIN

Morning rain delayed play on the external courts for at least an hour but matches at the roofed showcourts proceeded only slightly behind schedule, with twice Grand Slam champion Garbine Muguruza taking on Australia's Ajla Tomljanovic in the early match at Rod Laver Arena.
