I haven't heard any "the Yankees Are Coming, The Yankees Are Coming" promotions on 820 this year. The WWBA webisite posting IS from last year, and 2013 is a new season. (and as I write this I am listening to Oakland beating the Yanks 5-4 on 1040). Why the WHBO website is not promoting it, I don't know, but I would if I was running things. 1040 needs to make all the noise it can.
The Rays won't be leaving the market without a major collapse in attendance, similar to the Expos after the strike. The 2027 lease would also complicate any threatened move, I would bet. And the question would then still be, where will they draw better? Orlando is a possibility, but the broadcast market is at least 1/3 smaller than Tampa/St.Petersburg. Unless there was some dream of moving to Puerto Rico or Long Island, MLB would be leaving a top twenty market to go to... Portland or Charlotte?
