Roger Federer eight-time Halle champion German has defeated serve-and-volley player Mischa Zverev by 7-6 (7/4), 6-4 and reached the quarter-finals of the Halle grass court tournament for a 15th time.
Federer now has a 4-0 record against Zverev including a win this year in the Australian Open quarter-finals.
Federer, next faces 2016 Halle champion Florian Mayer for a place in the semi-finals.
Federer Said “Mayer plays very different to everyone else. He uses slice, he comes in, he chips and charges, he loops the ball and serves/volleys a little bit, so he’s really going to throw everything at me.
“I think he’s most dangerous on the grass. He’s a tough customer, plus he’s the defending champion. He hasn’t had the best season so far, so there is a lot riding on the match for him as well as for me because we both want to go deep into this tournament.”
