Taco Bell keeps putting together World Series promotions aimed at giving away free tacos for baseball feats.

Last year it was any player hitting a home run to left or left center field during Game 3 of the series. In 2002, it was hitting a floating target outside San Francisco’s AT&T Park.

This time, the quick service restaurant chain might just have found the formula to give “everyone in the U.S.” a free taco: if any player steals a base during any game of the 2007 World Series, U.S. consumers can pick up a free crunchy seasoned beef taco (retail value approximately 77 cents). The company says there's been a stolen base in every Fall Classic since 1990.

Redemption is limited to specific times. If the first base is stolen during Games 1 or 2, consumers can pick up a taco between 2 and 5 p.m. local time on Oct. 30 at participating Taco Bell locations; if it occurs during Games 3 through 7, the redemption time is 2-5 p.m. local time on Nov. 6.
