Besides this, he mentioned once Imanaga coming back they could move Horton back down to AAA. I believe it was to keep an eye on his innings. So that would leave Rea and Brown in the rotation. Which is less than ideal. Of course they need a starting pitcher. To your point, it would take pressure off the others, and limit innings from iffy pitchers. Ideally, I would like to see Brown and Horton around 100-110 innings during the regular season. Then they can be used in the playoffs. Either in the pen, if the Cubs get at least one solid pitcher at the deadline, or even in the rotation. With that in mind, they need a pitcher ASAP.
