Kyrgios overcomes tantrum, bagel to advance in Cincinnati

Nick Kyrgios has bounced back from a bout of tantrums and a disastrous second set to eliminate Borna Coric and advance at the Cincinnati Open.

The No.15 seed was pushed to a tiebreaker in the first set but overcame the Croatian 7-1 to strike the early blow in the match.

But it quickly went pear-shaped for the temperamental Australian, who lost his cool and composure in the second set before surrendering 6-0.

Kyrgios, however, rallied in the third set, the Canberran delighting the crowd with several shots between his legs on his way to taking the deciding set 6-3 in a match lasting one hour and 47 minutes.

The Australian No.1 will now face either South Korea's Hyeon Chung or Argentine Juan Martin del Potro for a spot in the quarter-finals.

Earlier, Novak Djokovic came from behind to beat Adrian Mannarino in the second round of the tournament.

Djokovic, the 10th seed, recovered from losing the opening set as he saw off Frenchman Mannarino 4-6 6-2 6-1 in two hours and six minutes.

Serbia's Wimbledon champion will face defending champion Grigor Dimitrov in the third round after the Bulgarian dispatched German Mischa Zverev 7-6 (7-5) 7-5.

Meanwhile, Zverev's younger brother, third seed Alexander Zverev, was eliminated by Robin Haase after he produced a surprise turnaround.

The Dutchman, ranked 55th in the world, advanced at the expense of world No.4 Zverev 5-7 6-4 7-5.

Haase, who last week kicked off his North American hardcourt swing by reaching the Toronto quarter-finals, converted six of seven break point opportunities in a match lasting two hours and 25 minutes.

Haase improved to a 2-2 career record against Zverev, including victories in their last two meetings.

"We've played four times now," Haase said. "The first time he literally kicked my ass ... that was the tournament where he actually came up. And, yeah, since then he's come a long way.

"And now I was there twice physically, mentally and game-wise I was there. And we have to be a little bit lucky as well against these top guys."
