Zverev wasn't initially in the match with the World No.257 replacing Tommy Haas after he pulled out with a calf injury earlier today but he proved an adequate replacement claiming a 6-4, 6-3 victory.

In the first set, Zverev took a break to make it 2-1 and from there held serve to make it 6-4. It was a similar story next up with an early break of serve making it 3-2 and taking control from there at 4-2.

In the final game, he broke serve again to claim it making it 3/6 of break points converted overall throughout the tie. As total points won showed with 46% compared to 54%, it was closer than the scoreline dictated but Zverev did the right things at the right moments to win through.
