The 32-year-old was released recently by the Marlins, who had signed him over the winter to work from the bullpen and provide rotation depth. Jackson ultimately pitched to a 5.91 ERA over 10 2/3 frames, striking out seven and issuing six walks.
The Cubs are still paying Jackson under his four-year, $52MM free agent contract. That’s offset, but not by much, to account for Jackson’s earnings with other organizations. Miami is obligated for a league-minimum hit after inking Jackson to a major league deal. San Diego will also pay Jackson at the lowest possible rate for whatever time he spends in the majors.
