Cubs recalled RHP Rafael Dolis from Triple-A Iowa. He'll take the place of Randy Wells on the active roster. Dolis was demoted to the minors last month after posting a 5.68 ERA and 11/17 K/BB ratio over 25 1/3 innings. The 25-year-old right-hander appeared to make some progress on the farm, compiling a 2.92 ERA and 13/4 K/BB ratio over 12 1/3 innings. He'll likely pitch in a set-up capacity.
