Three-time Grand Slam champion Andy Murray came from two sets down to beat home hope Thanasi Kokkinakis, advancing to the third round of the Australian Open on Thursday. Murray prevailed 4-6, 6-7 (4/7), 7-6 (7/5), 6-3, 7-5 in match which ended at 4:05 am local time. However, another controversy erupted after Murray won the fourth set and forced the game into a deciding fifth set. Murray, who had already used all of his bathroom allocations, wasn't allowed to leave the court to relieve himself. However, he was seemingly not happy on being denied another bathroom break, and fumed at the chair umpire Eva Asderaki-Moore.
