According to Joel Sherman, the Mets contacted the Colorado Rockies after they acquired Huston Street. The Mets offered Aaron Heilman, but the Rockies wanted Pedro Feliciano included as well, and the Mets walked away.
Going by this, the Rockies need a left handed pitcher. Why not offer Heilman and Scott Schoeneweis? He's under contract and a lefty that they need. They'll dump Street, and keep Manny Corpas as their closer, and everyone is happy.
If somehow, they can include Luis Castillo in this deal, and get a bag of balls in return, that would be a miracle.
The Rockies are likely still listening to offers on Street, so hopefully Omar Minaya is racking up the phone bill with calls to Denver. If he can land Street and rid the team of Heilman and maybe Schoeneweis or Castillo (or both!) then I, and many other Mets fans, will be very happy. Street might not be the best option for closer, but he's damn well better than anything the team currently has.
If the No. 1 scapegoat for the last two seasons is off the team in the process of bringing in a young closer, then Minaya will have earned his extension in my eyes. At least until the next deal.
