Theo needs to strike when the iron's hot. Go get Ubaldo right now, pull the trigger so he doesn't pitch tomorrow and we can have him throw before next Thursday.
This is a trade that I would be willing to "lose" slightly, i.e. overpay for him right now. The guy's stuff is electric, and with him, Beckett, Lester, and Buchholz, this team would be borderline unstoppable.
