According to Will Caroll of Baseball Prospectus, Manny may have played his last game for the Red Sox tonight:

Marlins get Manny Ramirez, one prospect (Red Sox), and cash (likely covering Ramirez’s remaining salary)

Pirates get Jeremy Hermida and three prospects (two Marlins, one Red Sox)

Red Sox get Jason Bay and John Grabow

John Grabow is a very awful lefty reliever and Jason Bay is an inconsistent but talented outfielder who is having a pretty decent year.  He’s also young and a better defender.  But still - not the kind of deal I get excited about.  This smacks of Theo having no choice and taking the best of what they can get.  The Marlins and Pirates on the other hand make out like bandits.  Manny has a club option left and if the team owner isn’t tight fisted he’s a major offensive threat in the NL East.  This might just have given the Marlins the divison.
