Did he really do that? what was he even arguing about he just lost fair and square to a better player.
Well he was complaining about the calls in the tiebreak so maybe that's why
Very immature behavior.
My friend is a physio at the tournament and he said that Grigor's coach (McNamara?) left as soon as he heard of the incident
. Said something like "I refuse to be in the same cab with that kid, he's crazy!". He also complained about a MTO Grigor took in some other match, something like "That's no time to take a MTO, I should have a talk with him".
