I am not sure of his innings being limited. Is that a thing if the pitcher is fully back from TJS and has pitched over 180 innings previously? And even if it is the Cubs have the other pitchers who can work in and out and all have innings limited. When Imanaga comes back they would have Imanaga, Boyd, Taillon, Alcantara, Brown and Horton. And, if they have a good enough lead in the division they can spot Rea from time to time. If Alcantara is healthy for the playoffs he adds a quality pitcher to the playoff rotation. I would be more worried about him back in form then I would be about limiting his innings.
And, honestly, doesn’t have to be him either. I just want someone asap to replace Rea in the rotation. Not many available just yet. I doubt the Dbacks are ready to admit selling yet. Same with the Rangers. I am not sure what the Braves might do. If they made Sale available he would be a good get. Maybe Eflin or Keller are also available now. As for the others, I don’t see teams deciding to sell at this time.
