According to Marlins beat tweeps, the Fish have released the biggest piece they received from Boston in exchange for Jeremy Hermida, LHP Hunter Jones. Jones pitched 1 2/3 scoreless innings in three games for the Marlins this season, back in May, and has spent the rest of his time in AAA, where he pitched 45+ innings with a 4.17 ERA, until he landed on the DL.
Well that trade worked out. (It's OK Larry. We're getting used to it.)
