Grigor Dimitrov is ranked 16th in the world in the ATP rankings, but is first for being a genuinely decent human being.
Despite being locked in a close match after a first set tiebreak, Dimitrov noticed that a young ballgirl was struggling with the heat at the Sony Open Tennis in Miami. Instead of passing it off, he took the time to help her off the court to the thunderous applause of the crowd.
It didn't matter that he ended up losing the match. He won the game of being a totally awesome guy.
