When things get tough on-court is often difficult to keep calm.
Garbine Muguruza failed to keep her cool during her match against Andrea Petkovic in Doha. The Spaniard was 1-4 down in the third set against Andrea to call her coach Sam Sumyk to get some advice. Eventually Garbine wasn’t apply with Sam to say “tell me something I don’t know”. Sam tried to keep his calm to say It seems that you know everything.”
Eventually Garbine lost the match 6-1 5-7 6-2… there was not much glory in that.
