One of the highlights of the St. Louis Cardinals' improbable run to a championship last fall has been captured on one of the new 2012 Topps Series 1 Baseball trading cards.

But it's not Albert Pujols' historic three-homer outburst in Game 3 of the World Series.

It's not David Freese's walk-off home run that won an epic Game 6.

It's not even Chris Carpenter's gutty pitching performance in Game 7.

No, the magic moment came from Game 4 of the NL Division Series when a furry rodent bolted across the field at Busch Stadium and gave the Cardinals their unofficial playoff mascot, the Rally Squirrel.

Cards second baseman Skip Schumaker was at the plate when the squirrel made his dramatic appearance. And Schumaker's 2012 Topps card only shows his right foot in the batter's box ... alongside the sprinting squirrel.

The squirrel may end up being nearly as valuable to card collectors as it was to the Cardinals. Beckett reports that the Squirrel and Schu version will only be available as a short-printed variation card, so a standard one with Schumaker's picture will eventually replace it in the set.
