He’s definitely been affected by this change in energy. It’s amazing the impact the crowd can have on a momentum of a match.
*Rinderknech 6-2 4-6 3-6 Fritz
Arthur Rinderknech is calling for more noise from the crowd after another hold to love - and they respond!
The cheers turn to boos when a line call goes against Rinderknech to start Taylor Fritz's service game. The line judge called it out, the umpire overruled and Fritz sent his shot long.
But when the umpire goes to check, she indicates there isn't a mark and the original 'out' call stands! That goes down about as well as you would imagine.
Fritz is unfazed, though, and a thumping forehand winner gives him a two sets to one lead. Cue more boos.
*Zverev 6-4 6-2 4-1 Molcan
