St. Louis, MO (KSDK) - A streaker is behind bars after trotting across the outfield naked during Thursday night's Cardinals-Phillies game.

The streaker, identified as 22-year-old Collin Grundstrom from Jefferson City, appeared on the field before the seventh inning and was eventually tackled and apprehended by Busch Stadium security and police.

Authorities retrieved towels from the Phillies' bullpen to cover Grundstrom while stadium personnel got the man's shorts from the stands.  He was escorted from the field out of the Cardinals bullpen.

Grundstrom, charged with lewd and lascivious conduct, apparently told police he'd lost a bet.

The Cardinals lost Thursday's game 10-9.
