Defending champion Alexander Zverev moved into the quarter-finals of the BMW Open in Munich having come from behind to beat fellow German Yannick Hanfmann.

Zverev eventually posted a 6-7 (12-14) 6-4 6-2 victory and will face another compatriot in the next round in Jan-Lennard Struff, who beat another German, Yannick Maden, 6-3 3-6 6-3.
