This American referee tolerated some hard fouls from Uruguay. Diogo, for example, saw the yellow, but then he continued fouling and Toledo allowed him to break the rules. Only 2 Uruguayans saw yellow card. Very few in comparison with the way they played.
When Vicente Sanchez scored, Bolivians protested because of a possible off-side. Assistant didn´t flag and Toledo convalidated the goal. TV couldn´t show this very well, so we can say the referee was OK.
From my point of view, the way Bolivian defender Peña pushes Rodriguez at minute 52, can´t be considered as a legal action. If I had been the referee, I would have conceded the penalty.
Both teams have to improve a lot if they want to continue alive in this Copa America. Both can be in quarterfinals if they win next games.
