The German was 5-3 in front in the opening set and he served for it in game 10 (he lost just three points in the opening four service games), only to get broken and lose all the momentum, unable to recover until the end of the match.
Mischa was off to a better start, holding with ease and putting Tomas under all kind of pressure on the return, creating six break points in Czech’s first four service games. He couldn’t convert four in the opening game but a forehand winner in game three gave him the advantage that he carried until game 10 when he could close the set.
Instead of that, Berdych broke back out of nowhere and this turned the strings of the match into his hands. Tomas served at love in game 11 and he earned another break with a solid return in the following game for 7-5. The Czech did everything right in set number two, losing just four points on serve and finding the way to break Zverev in game four that proved to be the crucial moment of the set.
A volley winner at the net gave Tomas the lead and he carried it home with no troubles, holding at 15 in game nine to advance into the last 16. Alexander Zverev was more successful than his older brother, scoring a 6-4 6-3 triumph over David Ferrer in an hour and 24 minutes, improving his mediocre Rotterdam score to 3-3.
