The Trop is such a terrible place to play that I think the only way to even be marginally comfortable playing there is for it to be your home park and thus the place where you play 81. It works for the Rays unfortunately as they have some additional confidence playing there...almost like if you were Sox and you knew DeJesus was going to be lost out there in LF at Fenway.
At the Trop you know something idiotic is going to happen....like losing it in the lights or losing it in the roof or having it bang off the catwalk.
I guess there is no feasible way out of the contract the Rays have with the place. So, even if they want to leave, they are stuck.
I can't see playing there being worth more than one win for the Rays though......if that.
