Michael Hill, current President of baseball ops, assuming GM duties for the Fish. I think he's kind of a doofus?
He was an assistant to Beinfest and has been Jennings' boss for the past year. It's an in-house reassignment so I wouldn't expect any major changes. I don't really know what that means because the Marlins recent personnel decisions seem tactically driven without any apparent long-term strategy. Are they trying to build their organization from the ground floor? are they trying to compete now? who can tell? Some of their deals have worked out in isolation but the team seems constrained financially and talent-wise to topping out around the .500 mark.
Hill is African and Cuban-American which makes him the highest ranking minority in a MLB front office position so there's that
I imagine that Loria's pretty fickle, too. He can't be easy to work for.
The mid-season Latos etc. deal was just a pure salary dump. They gave up a comp balance pick that was better than any of the minor leaguers they got from LA!
Heaney deal was also horrible, obviously. Feel bad for the six Fish fans that are left. But hey two WS!
The Heaney deal returned Dee Gordon who was a 4.9 WAR player this year and is cost-controlled through 2018. He's a whole lot more valuable than a one year rental of Howie Kendrick. The Marlins' organizational depth is at pitcher and you have to put some major league talent on the field. I like DeSclafani but I think the Latos deal is defensible from the Marlins' perspective. Buy low on a distressed asset and hope he brings a bigger return at the deadline. It's basically a cut-rate version of the Beane/Holliday gambit and worked out about as well.
For all Loria's flakiness, his front office has been relatively stable. There have only been three GMs since he bought the club. Larry Beinfest, Jennings and Hill were all inside hires. Their oddball decisions have been with on-field leadership. The hiring of Trader Jack worked out great and Ozzie Guillen was a disaster.
ETA: they sure gave Joe Girardi the quick hook
