Patrick Franziska plays inefficiently. He makes lots of unforced errows, which make all his strategies and techniques become meaningless. If professional players make too much unforced errors, then they become less efficient than amateur players.
@@callingthecopswinkler4924Indeed. Who knows what OP is talking about. At this level unforced error are nearly non existant. If a player makes a "mistake", it's due to the trickery, tactics and speed, spin of the opponent who makes winning shots nearly impossible, but extremely risky.
