Head of security at Busch Stadium Joe Walsh tells the St. Louis Post-Dispatch that Colin Grundstrom "appeared to have been drinking" Thursday night.
The admission comes as no surprise considering Grundstrom stormed the field without wearing any clothes at the start of the seventh inning of the Cardinals-Phillies game Thursday.
AP reports that the 22-year-old streaker who ran naked onto the field says he did so because he lost a bet. Being on the wrong side of this wager could end up being very costly for Grundstrom, as he has been charged with violating two city ordinances - being a spectator running on the playing field, and lewd and lascivious behavior. Grunstrom spent Thursday night in jail.
