Who wants to be eight years old and have to put on the colors of the team you hate the most? If I was eight, and had to play for the "Yankees", I would've probably cried at the very least and likely quit. (I still wouldn't like it very much if my High School team adopted the name)
Not to mention, what a thrill for the kids getting to play in such a nice ballpark for a game. Great idea by one of the best promotional teams in minor league ball, It's a brilliant marketing campaign they've come up with. I wouldn't be surprised if Little Leagues in the tri-state area start doing the same thing with the Red Sox, and it wouldn't bother me.
Like I said, it is a brilliant marketing campaign by the Spinners, not hatred toward the Yanks...
