SATURDAY: Jackson cleared waivers and has been given his unconditional release, according to Clark Spencer of the Miami Herald (Twitter link).
TUESDAY: The Marlins have designated righty Edwin Jackson for assignment, the club announced. His roster spot will go to southpaw Mike Dunn, who will be activated from the DL for the first time this season.
Jackson, 32, signed on with Miami on a league-minimum MLB deal over the winter. He had previously been released by the Cubs, who are still paying out the final season of the four-year, $52MM contract he inked with Chicago before the 2013 campaign.
While the 14-year veteran had solid results last year working out of the pen, he’s scuffled to a 5.91 ERA in 10 2/3 innings thus far in 2016. Jackson has managed just seven strikeouts against six walks in his eight appearances on the year.
Meanwhile, the 31-year-old Dunn will be looking to bounce back from a tough 2015 season and forearm issues earlier this year. He was one of the game’s more effective left-handed relievers over 2013-14, when he compiled a 2.89 earned run average in 124 2/3 innings, with 10.0 K/9 against 3.6 BB/9. Dunn is in his final season of arbitration eligibility.
