At Little League, Luis is catching fly balls, stealing bases, and hitting like a champ. But there is a problem: he thinks he's getting good luck from the snacks he samples at the supermarket before every game. Then one day his mom goes directly to the field and he has a horrible practice. The day she skips the stop at the store before a game, he strikes out twice.

Luckily, Luis's father understands and convinces him that practice and concentration matter much more than any superstition.
