I think both Moore and Chol would both need to be upgraded to the main list if they are to stay, however I am unsure it they get automatic 2 year contracts or just a single year.
Just to revisit the 2018 list from my previous post.
Townsend (50-50), Broad (2 Years), Grigg (1 Year), Houli (1 Year), Conca (1-2 Year), Markov (50-50), Drummond (1 Year), C Ellis (2 Years depending how he finishes the season), Menadue (2 Years depending how he finishes the season), Soldo (2 Years), Short (2 Years), Bolton (2 Years)
Llyod and Miles to get delisted this year to make room for 3 draftees 1 Lynch and 2 Rookies
Side Note: Stengle and Baker would both need to have spots available for them on the main list if they were to stay the year after
