Tireless Dominic Thiem came from a set down to outlast German Alexander Zverev and make his first Australian Open final Friday, booking a showdown with seven-time champion Novak Djokovic. The 26-year-old fifth seed, the first player from Austria ever to reach the Melbourne decider, battled past seventh-ranked Zverev 3-6, 6-4, 7-6 (7/3), 7-6 (7/4) on a sweltering evening. mp/th
