Link to the full policy for March 26-April 30 games: https://www.mlb.com/brewers/fans/2020-update?partnerId=it-1182103-7550-1651371 Assuming games are even played in front of fans this year (which at this point seems unlikely), singling out Opening Day seems especially detrimental to ticket-holders, as there's no refund or credit option attached: I'd expect many people to be extremely risk-adverse immediately after the quarantine is lifted, so there may be zero aftermarket value for those ticket-holders that do not want to attend and who try to sell their tickets instead. I could see those ticket-holders being forced to take huge or complete losses by this policy. I'd hope they'd offer refunds or credit towards 2021 to accommodate those who aren't willing to risk full parking lots or stadiums this year. I'm guessing a lot will change with these policies in the coming months, but for now this Opening Day policy seems poorly fleshed out.
