The Hudson River Rats are a men's amateur baseball team playing in the Western Wisconsin and Eastern Minnesota region of the United States during the spring and summer. Their target audience includes baseball fans, college students, and baseball players.


Since 2001 they were using a modification of the Albany River Rats hockey team's mascot for embroidery on their hats. They were looking for an image of a muscular, playful, and confident rat-- preferably holding a baseball bat or throwing a baseball.
