According to FOX Sports' Jon Morosi, the Tigers had interest in trading for Colorado's Brad Hawpe, but it doesn't appear that he will be moved by the Rockies. From ESPN's Jayson Stark:
#Rockies telling teams they couldn't trade Brad Hawpe right now no matter what. Might need him to play 1B depending on Helton health #trades
Although things can change in the next four hours, it doesn't seem likely if the Rockies are flat out telling teams Hawpe won't be dealt.
