Acapulco is pretty slow, humid and sometimes even windy. Tricky place to play really.
Sascha needs to do a better job adjusting his game to play unorthodox players like Mahut, Granollers, Jaziri and company. Looks like he's always a mess against this kind of player. I assume he would struggle a lot playing his brother too.
He admitted a few times in German media that he's Mischa's ostrich, so yeah good guess
