We've seen Campana in two games earlier this year, and the D-backs won both. His main value to this team is as a pinch runner, as he brings quite the burst of speed, and will be valuable as the fifth outfielder, although I don't expect to see him start very much, if at all. Skaggs being sent down makes it pretty well certain that Trevor Cahill makes his return, and in fact, he is already down as the starter for Saturday in Pittsburgh. With Eury De La Rosa doing well, look for Chaz Roe to be optioned to make space for Cahill. With that move, our rotation for the next few games is set with McCarthy-Cahill-Miley in Pittsburgh, then Delgado and Corbin to pitch the first two games of what could be a key series for postseason hopes in Cincinnati.
