Ellington will be called up by the Marlins prior to Friday's game against the Reds, Clark Spencer of the Miami Herald reports.
Ellington will take the roster spot of the recently departed David Phelps, who was sent over to Seattle on Thursday. During 11 adventurous appearances in the big leagues this season, Ellington allowed 10 earned runs off 19 hits and 13 walks while striking out 18 over the course of 11.2 innings. He figures to slide into a low-leverage role while trying to work back into the form that he showed the past two seasons.
