Djoker rallies in comeback win, young star crashes out
Novak Djokovic came from behind to beat Adrian Mannarino in the second round of the Cincinnati Open, while third seed Alexander Zverev was eliminated by Robin Haase.
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.
The Serbian Wimbledon champion was joined in round three by Haase after he produced a surprise with a turnaround of his own.
The Dutchman, ranked 55th in the world, advanced at the expense of world No.4 Zverev by defeating the German 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."
Zverev's older brother Mischa was scheduled to face defending Cincinnati champion Grigor Dimitrov but their match was delayed by rain.
Australian No.1 Nick Kyrgios continues his challenge at the ATP Masters 1000 event later when he plays world No.21 Croatian Borna Coric in round two.
