Nobody is going to give a 3rd starter at least for those. I'd be willing to give up one or even two (If the pitcher is controlable for a few year) of Castro, Osuna and Norris. Also, we could give up Pompey if it's really worthwhile because Alford looks like a good option for the future too. I'd do Chapman and Cueto for Castro, Norris and Tepera with the Reds. That would be a trade that would really help us in the bullpen and Cueto would likely keep similar numbers due to the fact that he is already pitching in a sandbox. It could also turn in the advantage of the Reds if Castro and Norris fully pan out
