The new special advisor to baseball operations is an old friend and teammate of CEO Derek Jeter."It’s an exciting (though not too surprising) addition to the Marlins organization: longtime major league catcher Jorge Posada will become a special advisor to their baseball operations department http://www.bravesfanproshop.com/authentic-nick-markakis-jersey , according to SiriusXM/Five Reasons Sports host Craig Mish.Jon Heyman of Fancred quickly confirmed the report.Posada, 47, and CEO Derek Jeter have known each other for most of their lives. Both were drafted by the Yankees in the early 1990s who spent parts of 17 seasons together (1995-2011) at the highest level. They own World Series championship rings from 1996, 1998, 1999 Scott Kazmir Jersey , 2000 and 2009, key cogs in the most recent MLB dynasty.A native of Puerto Rico, Posada and his family are longtime Miami residents. The Marlins reportedly had free-agent conversations with him about a contract for the 2012 season, but he ultimately decided to hang up his cleats. The dangerous switch-hitter slashed .273/.374/.474 with 275 home runs in 1,829 regular season games (not to mention all his October adventures).After retirement Kurt Suzuki Jersey , Posada occasionally contributed stories to Jeter’s The Players’ Tribune, which specializes in delivering content directly from athletes to fans. He was also spotted at Marlins Park multiple times last season (as pictured above).Fish Stripes has learned that, even though the Marlins have yet to announce the position, Posada is already working directly with their players at the Roger Dean Spring Training complex in Jupiter.It’s worth noting that the MLB “special advisor” gig can be a stepping stone to more visible roles. Brad Ausmus, for example http://www.bravesfanproshop.com/authentic-nick-markakis-jersey , held a similar title prior to succeeding Mike Scioscia as Angels manager this past offseason.Meanwhile, Marlins skipper Don Mattingly is entering the final year of his contract. MIAMI (AP) — The Miami Marlins have designated for assignment infielder-outfielder Derek Dietrich, who had been with the team since 2013.Dietrich is eligible for arbitration after making $2.9 million this year, when he hit .265 with 16 home runs in 149 games while playing mostly in left field. He’s a .254 career hitter with 60 homers.The move takes Dietrich off Miami’s 40-man roster, opening a spot for one of seven minor leaguers who were added Tuesday to protect them from next month’s Rule 5 draft at the winter meetings. The Marlins have seven days to trade or release Dietrich http://www.bravesfanproshop.com/authentic-nick-markakis-jersey , or send him outright to the minors. Because he has three years of major league service, he could refuse an outright assignment and elect to become a free agent.Dietrich’s departure means All-Star catcher J.T. Realmuto has now been with Miami longer than any other player.
