Fitts will start Friday against the Twins, Christopher Smith of MassLive.com reports.
Fitts most recently made a spot start Sept. 13 in place of Tanner Houck, who was dealing with shoulder fatigue. Even with Houck back in action, Fitts will get another turn through the rotation. He has yet to allow an earned run across 10.2 innings, though his 4:4 K:BB is less impressive.
