The Brewers have done a much better job connecting with fans which gets 500,000 more people to Brewers games than the Twins despite the Twins being able to draw from a metro population roughly twice as large. In 2023 the Brewers drew 2.5M fans out of a population of 1.5M. The Twins drew 2M fans from a population of 3M.
I think a lot of that is the Brewers are trying harder to win than the Twins.
