I'll give you two reasons why we should bring Cease up now 1) The difference between Giolito this year and Giolito last year. 2) The difference between Moncada this year and Moncada last year.
Sox did the same thing with both guys: brought them up for a brief time in August of 2017. Going through September, everything looked peachy. But for both guys, 2018 was a huge let down, using the word terrible (less for Moncada) is not off base.
But this year?!!! Given a full year, then an off season to ferment and correct things, the White Sox have two very special players now. Since we saw what happened with both of them when they were brought up in August and how the next year was a lost year, why repeat that mistake with Cease?
I say don't follow that formula. Bring Cease up now, give him more than 8 or 6 weeks in the majors to learn and (yes) struggle. I say give him the end of June, then July, August, and September; whatever he can take for pitched innings, but let it be facing major league pressure and major league bats. Giolito and Moncada had to struggle first, let's get that struggle over with Cease now. Why waste next year?
Here's a crazy idea (and I know I keep putting this out there), but let's try to win. Let's try to win now, and absolutely, let's try to win next year. Is Cease great? Is he perfect? I don't know, but he's a hell of a lot better than the guy we're throwing against the Nats tonight. Pitch Cease in the majors and let him start taking his lumps and learning, just like Lucas and Yoan did last year, but let's get that out of the way so that the Sox can start winning for real next year.
