Nick Kyrgios fed off a febrile atmosphere to save two match points on his way to a 5-7 6-4 3-6 7-6(2) 6-4 comeback victory over Frenchman Ugo Humbert in the second round of the Australian Open on Wednesday. Roared on by a crowd making up in passion for what they lacked in numbers, Kyrgios scrapped his way back into the contest time and again to secure a third-round date with U.S. Open champion Dominic Thiem. He triggered bedlam when he dug deep to save Humbert’s match points in the fourth set and proceeded to even up the contest by dominating the tiebreak.
