All German tie in the first round of the Halle Open. Zverev fresh from a brilliant clay court season in which he lost a five setter in the semi against Tsitsipas, was pushed the distance by his unseeded compatriot. Zverev rallied from 4-1 down in the first set after an error strewn opening 5 games. But the number 3 seed found his stride when his serve started finding its mark.He won an eye catching 89% of his points on first serve, serving at 70% first serves. Koepfer was also guilty of double faulting on important service points. Watch 4-4(40-15) Zverev.

The left handed Dominik Koepfer started the second set really well and broke Sasha in the seventh game 4-3 doing as best what lefties do, that is using that solid forehand. He safely negotiated the next service game to clinch the set. Watch third set 1-1(30-0) focusing on the service motion by Sasha. Look how high Zverev tosses the ball, he doesn’t allow it to fall too low and hits it almost a millisecond after tossing it generating the speed. That was the key to this solid service display. FAIRLY COMFORTABLE THIRD set going to Sasha and will face Frenchman Ugo Humbert in the round of 16.
