Zverev fights back to win opener in Munich title defence

Alexander Zverev began the defence of his Munich Open title with a hard-fought win over fellow German Yannick Hanfmann.

The top seed and world No.3 came back to win 6-7(12) 6-4 6-2 after losing a gripping first-set tiebreaker against the world No.118.

“I am always happy to get a win like that,” Zverev told atpworldtour.com.

“Obviously he played one of the best matches of his life today, so I wish him all the best and I hope he is going to continue playing like this in the next few weeks.”

Zverev goes on to face another German, Jan-Lennard Struff, in round three.

Fourth seed Hyeon Chung of South Korea beat German wildcard Matthias Bachinger 6-1 6-1 and next faces Slovakian qualifier Martin Klizan.
