For all the IDIOTS in MTF who doesn't understand shit of life and still they talk:
Berlocq did that after winning the match, after Kohly went out of the court.
BUT BEFORE THAT: He gave a hug to his rival, he went to the German team and shake hands with every member, and hugged all the argentinian Davis cup team.
Then, when they announced him, he went to the court and do that.
He was actually really classy with his rivals, but then the emotions surfaced, after they left the court.
Agree it was not bad sportsmanship but I completely understand why some would find this pretty silly behavior.
