I agree at allThe worst match ive ever seen Nadal play on clay
The way Nadal return of serve was tragic. Nadal ROS today was at ATP challenger lever. Everything bad for Rafa come from this basic shot.
Nadal short ROS give Zverev many free points to pump his confidence.
Evertyhing come from frequent short ROS, make Rafa nervous and lack of confidence to see oppenent make easy winners every point.
Rafa have to practse so much on ROS in the last couple of week also in the prospective for Wimbledon and hard court season. He maybe have to try to change the possitioning on ROS to come closer to the baseline and use block ROS sometimes if it neccessary.
