This is Myrtle Beach Pelicans manager Joe Mikulik. He disagreed with a call the umpire made, so he decided to voice his displeasure. Things got out of hand quickly.
Mikulik has a bit of a reputation as a, shall we say, fiery competitor. In 2006, he threw a tantrum which he punctuated by pouring a bottle of water on home plate. In 2012, he removed third base and gave it to a fan.
So the umpire in this case got off easy. At least Mikulik left the field intact.
