MELBOURNE, Australia --- Jannik Sinner has upset Novak Djokovic to reach the Australian Open men's final, ending the 10-time champion's career unbeaten semifinal streak at Melbourne Park. The 22-year-old Italian broke Djokovic's serve twice in each of the first two sets but missed a match point in the third set of a 6-1, 6-2, 6-7 (6), 6-3 victory Friday that earned him a place in a Grand Slam singles final for the first time. On his second match point, 55 minutes later, he made no mistake and completed his third win in four head-to-head encounters since a straight-set loss to Djokovic in last year's Wimbledon semifinals.
