WASECA, Minn. - Authorities suspect the fire that destroyed part of Tink Larson Field in Waseca was intentionally set.

Firefighters were called to the iconic Minnesota ballpark the night of April 6. Flames quickly spread to the concession stand, the grandstand, and swallowed part of the grandstand roof.

The baseball field, home of the Waseca High School team, has been there since 1938. It was named after Larson, the longtime head baseball coach, in 1994.
