Liberal played on Sunday and won, 8-0, moving them to the semifinals of the tournament. Kaiser's family wanted the team to play.

The general manager of the team said, "We just lost a little, 9-year-old Bee Jay and it’s incredibly sad. No one wrote us a book to tell us how to do this. We’re just dealing with it the best way we know how and that’s to keep coming out and keep honoring Kaiser on the field.”

A GoFundMe page has been set up to help Kaiser's family.
