Because it's all about getting the company/charity's name out there. The Brewers, like all teams I'm sure, have that sort of thing. The "Menard's" Big Inning, etc. If the 1,2,3, and 4 hitters for a cycle in the 6th and only the 6th inning, then 1 lucky person out of 3,000,000 will win a $100 gift certificate from Menards, only to be used at Dallas' Menards, 1000 miles away. It's stupid, but advertising is the name of the game.
