MLB.com - Tampa Bay Rays Conquer T-Shirt by Majestic Athletic

I don't get this shirt. Is this like their official AL East Champion shirts and the Yankees are the Dynasty they are referring to? Or are we the dynasty and they are just guaranteeing victory in the ALCS? I think it has to be the Yankees right? Because we won't officially be a dynasty until the playoffs are over. But at the same time how can Tampa Bay say the Yankees are still a Dynasty? I mean does that mean the Twins are a dynasty too? Seriously this is why it is bad for baseball to have the Devil Rays in the ALCS. They don't even know how to make shirts right.
