i wouldn't say that pena has never lived up to the hype. first, there was not all that much hype for him. second, he never really got a legitimate shot until last year. the rays don't have a very good team, but they have an ok lineup. he will probably not repeat last year, but he's still going to be good. 5th round might be a bit of a reach, but i wouldn't say you killed your season. if you had said 3rd round, that'd be a different story. even if he turns out to be a 7th/8th round quality player, you're not going to be disappointed.
such is life
