This is one of the greatest baseball promotions that has ever happened!
The Madison Mallards are honoring Nirvana and how 35 years ago, in the spring of 1990, they went to Wisconsin to record their new album Nevermind. It went on to be kind of successful, if you haven't heard.
Fast forward to now, and the Madison Mallards just made the announcement that on July 5th, they will play as the Madison Neverminds! They have the duck in a pool, like the kid on the album cover, and other Madison Neverminds gear that is really cool.
You can check out more about the game and the Madison Mallards / Neverminds here. I love it!
