Product pitched by a pitcher

KOOLAID

Think of the bright powdered drink often mixed in a pitcher for kids.

This clue plays on the double meaning of "pitcher." One definition is a baseball player who throws pitches, while the other is a container for liquids. The answer, KOOLAID, is a drink often served in a pitcher, and the wordplay hints at it being "pitched" (or promoted) by the baseball kind of pitcher. It’s a clever nod to how the drink is both stored and advertised.
