Chung hands Djokovic a dose of his own medicine

Upstart S. Korean outlasts six-time champion to advance to quarters

MELBOURNE - For Novak Djokovic it must have felt like some nightmarish fight to the death against a clone of himself on Monday as Chung Hyeon stunned the six-time Australian Open champion with a display ripped straight out of the Serb's textbook.

The 30-year-old Djokovic, who has ruled Rod Laver Arena like no other, simply had no answer as Chung, nine years his junior, wore him into the ground to win 7-6 (4), 7-5, 7-6 (3) and become the first South Korean to reach a Grand Slam quarterfinal, where he will face American Tennys Sandgren.
