The Diamondbacks and Marlins had worked out a trade that would have sent Shelby Miller to Miami in exchange for three starting pitchers, only for Arizona ownership to shoot down the deal, a Marlins executive tells USA Today’s Bob Nightengale. The two sides had been linked in talks about Miller, with Miami right-handed pitching prospect Luis Castillo reportedly mentioned as a trade chip before Castillo was dealt to San Diego as part of the Marlins’ deal for Andrew Cashner. As Nightengale writes (semi-facetiously), the reason given by D’Backs ownership was that such a trade “just wouldn’t look good,” considering the stunningly big trade package the Snakes gave up last winter to acquire Miller from the Braves.
