Novak Djokovic produced a surprising comeback to defeat Germany’s Alexander Zverev, the seventh seed, 6/7 (6), 6/2, 6/4, 7/6 (6) to roll into the semifinals of the Australian Open.

In the women’s draw, Serena Williams defeated Romania’s Simona Halep 6/3, 62, while Japan’s Naomi Osaka tamed the wily game of Taiwan’s Hsieh Su-Wei 6/2, 6/2.

He opened serving with an ace but double-faulted twice en route to concede the break. Zverev hammered two aces to win clinch the second game and also took the fourth game for 3-1.
