In what was described by commentators as the match of the Australian Open 2018, World No.1 Simona Halep narrowly made it through to the round of 16 on Saturday after edging out American Lauren Davis in an epic 3-set contest that ended 4-6, 6-4, 15-13. Up in the first set, the world number 76 seemed to have Halep rattled as she blasted her powerful backhand shot past the Romanian, reports Xinhua news agency. But when the two squared off in the second set, the tournament's top seed regained her composure and began to take control of the tussle. It appeared over when Halep served for the match at 5-4 in the third set. However a desperate Davis was able to hold on and break Halep.
