This is the dumbest idea ever. No one cares about the Rays now. They certainly aren't going to care about them if they only get them in April/May or something like that.
It makes sense if it’s two cities are nearby like Golden State for example. They play in both San Francisco and Oakland. I’ve seen other teams play in two cities/towns in close proximity like New York/New Jersey, Los Angeles/San Diego, San Antonio/Austin, and NOK (New Orleans/Oklahoma City). I feel bad for the players and coaches because they have to be forced to get passports/visas and travel across two countries.
Just a ploy by the Rays/MLB to motivate the City of Tampa/Hillsborough County to get their act together and build a proper stadium in a location where people will actually go to it.
