Viva El Birdos, a St. Louis Cardinals community

Thanks to D-Dee for the gif. This is from a WGN video of a play that happened on April 16, 1969 between the Cubs and Cardinals at Busch. Mike Shannon hits a ball down the line that is a sure double, only to have it bounce off the umpire and back to Ron Santo, who makes the throw. Shannon then plows into Beckert, injuring him. Here is a newspaper article about the play.
