I think Pena should def be on that list. I have watched him all year and he has changed that swing and seems to be only getting better. Rumor has it he may go to the yanks too, which would increase his value, sucks for the Rays if it happens
Are these rumors of a mid-season deals?
It would increase his value theoretically, but I would also be worried about how he handles the pressure (though wasn't he already in pinstripes for a short time recently) of the constant scrutiny. It would be an interesting turn of events, surely.
TB's offense is pretty good though, so I don't think his value would increase that much. Combine a decrease in opportunities because of a drop in the order, plus the increased pressure and I am not so sure that's where I would want a player who just recently has started having ANY kind of success at the MLB level. He definitely would not be hitting in the cushy 5 spot. I am not saying he would necessarily flop but he has finally gotten comfortable in the Bigs, in a TB uniform, which has to be one of the lowest pressure environments in baseball. I wouldn't be extremely confident that his success would continue if he were to switch teams again.
That said, he should definitely be on the list.
