Fans at the Cardinals-Phillies game Thursday got a different kind of spectacle, as a streaker ran through the outfield wearing nothing but a smile.

Busch Stadium’s head of security says 22-year-old streaker Collin J. Grundstrom “appeared to have been drinking.”

Grundstrom, of Jefferson City, Mo., ran out onto the field before the seventh inning of the Cardinals’ 10-9 loss to the Phillies.

Grundstrom was held overnight at a city jail and was charged with violations of two city ordinances. Grundstrom was charged with being a spectator running on the playing field and lewd and lascivious behavior.

Grunstrom told police he ran onto the field because “he lost a bet.”

Cardinals third baseman David Freese told FOXSportsMidwest.com’s B.J. Rains that he wasn’t concerned for his safety when he saw someone on the field — “He’s naked so I don’t think he’s carrying much. That relaxes that bit of the drama. I guess naked is better. Less to worry about.”
