You could go to Toys R Us and ask where the baby toy section is and there you'll get a baby's baseball mitt.

If you can't find one online, you can easily have one custom made at a trophy/team apparel store.  My in-laws owned one, and they were always doing custom shirts for me.

The Fighting Illini have a store. It can be found here\nhttp://fightingillini.collegesports.com/store/  I did a search and went through the categories and found a jacket/windbreaker here http://store.fansonly.com/marketplace/store_contents.cfm?cart_id=&store_id=180&dept_id=2123&product_id=72155 but you can look around for yourself if you don't like that one.
