The Cardinals ended up losing 2 to 3, but in game four the Rally Squirrel made another appearance and brought the Cards some good luck.
In game four, just after the Phillies threw a pitch to second baseman Skip Schumaker, the squirrel darted out from the stands and crossed home plate. Pitcher Roy Oswalt protested when the umpire called the pitch a ball, because he claimed he was distracted by Rally Squirrel.
The Cards went on to win 5 to 3.
Since making his appearance on the field, Rally Squirrel has shown up on numerous T-shirts, hats and other merchandise. He even has a Twitter account (@BuschSquirrel).
"It's one of those neat things that comes around during postseason baseball, whether it's a song or gesture or even a squirrel," Abernathy said. "Every year something comes up, and so this year, this is our twist."
Cardinal fans may remember a similar squirrel that caused chaos during a Cards vs. Pirates game in 2007.
