Detroit Tigers Announce COVID-19 Refund Guidelines
As of right now, the Tigers are undefeated.
Basically, you have two options: you can get a full refund or a credit towards a future game. With the credit, you'll also receive an extra 30% over what you paid. So far, that's the biggest bonus of all the MLB teams.
Unfortunately, if you purchased your tickets through a broker like StubHub, you're subject to THEIR refund policies, which have a reputation to absolutely suck.
As far as games being scheduled, the MLB is holding out that they can push the season to start in late June/early July and only have 100 games.
