PHILLIES FAN RUNS OUT ON THE FIELD & GETS TASERED! IF HE WAS NAKED IT WOULD HAVE BEEN A CLASSIC!

A Phillies fan was tasered by cop after running onto the field during Monday's game against the St. Louis Cardinals, sparking a police investigation into whether the officer used force appropriately.

The fan jumped a fence at Citizens Bank Park, dodging two security officers in the bottom of the eighth inning against the St. Louis Cardinals.

One officer used a Taser and the fan went down in a heap.

Several Phillies placed gloves over their faces and appeared to be stifling laughter at the wild scene.

Phillies spokeswomen Bonnie Clark said the police department is investigating the matter and discussing with the team whether using the stun gun was appropriate.

Police spokesman Lt. Frank Vanore told The Philadelphia Inquirer police internal affairs will open an investigation to determine if the firing "was proper use of the equipment."

The teams said it's the first time a Taser has been used by police to apprehend a spectator who ran onto the field.

The fan was a 17-year-old male and he will be charged with criminal trespass and related offenses, the team said. The Phillies did not release his name because he is a juvenile.
