Thanks, Mookie Betts Thursday is the day when you can cash in on Taco Bell's "Steal a Base, Steal a Taco" promotion. During the World Series, Taco Bell promised if a player stole a base, they would give you free tacos. Mookie Betts of the Boston Red Sox did it during Game 1. How do you get your free taco? Stop into any participating Taco Bell location today between 2 pm and 6 pm local time and pick up a Doritos Locos Taco. Remember, the free tacos are while supplies last and you only get one!
