An unidentified man ran on the field tonight at Busch Stadium during the Chicago Cubs-St. Louis Cardinals game.
According to Deadspin.com, there were actually a series of these pranksters.
On a video (below) shot by a spectator, one man is being taken off the field by security as another one runs on.
The second fan is quick enough to outrun a security guard in right field, and several more security guards in the infield.
As the crowd cheered, he somersaulted over home plate, noted Yahoo! Sports.
A close-up video was shot by another crowd member and posted on Instagram.
