12:57pm: The Marlins announced that Rea has indeed been traded back to San Diego in exchange for Castillo. In essence, then, last Friday’s swap boils down to Miami acquiring Cashner and Guerrero in exchange for Cosart, Naylor and Capps.
12:52pm: The Marlins will be getting Castillo back from the Padres, tweets Rosenthal.
12:49pm: In a fairly stunning bit of news, Ken Rosenthal of FOX Sports reports that the Marlins will send right-hander Colin Rea back to the Padres (links to Twitter). Rea left his Marlins debut with an elbow injury and was quickly placed on the 15-day disabled list with an elbow sprain. Yahoo’s Jeff Passan tweets that the Marlins were “absolutely livid” and felt as though they were traded damaged goods by the Padres. Rosenthal notes that the exact structuring of the deal isn’t exactly clear, but the Padres will effectively trade Rea back to San Diego in a separate deal and keep Andrew Cashner, who came to Miami along with Rea in Friday’s seven-player trade.
Rea fired off 3 1/3 shutout innings in his Marlins debut, allowing just a lone hit and no walks with four strikeouts before departing with the aforementioned elbow injury. It’s not clear precisely how Miami will be compensated in this instance, as the swap is virtually unprecedented in nature. The Marlins sent first base prospect Josh Naylor, hard-throwing Class-A righty Luis Castillo, injured reliever Carter Capps and right-hander Jarred Cosart to the Padres in that deal in exchange for Rea, Cashner and right-hander Tayron Guerrero.
