With everything that has gone on so far I am wondering if Chapman's agents/handlers knew he was better than the intial reports from the WBC and were all over the contract the Reds offered because they figured he would play right away and get to the big time contract sooner.
That being said, my opinion is the Reds should send him to the minors until 6/1 for any reason they can make up. The Reds 5th starter is only scheduled to make 5 starts between opening day and 6/1. If you are telling me by skipping 5 starts I can control the guy at decent money for 5 years vs 3 years its a no brainer.
I will say he is going a long way toward making the decision for the Reds really difficult. If I am Dusty and he has one more dominating start, I pull my catchers aside and say "hey I would not be pissed if you happened to tell the hitters what pitch is coming." Although the way he is throwing even that may not matter
