@yankblan My memory isn’t the greatest at times. I just told him what I thought happened during the last time I saw a draft with a traded pick. The team trading the pick made the pick and the player belonged to the other team. I assume this player then cannot go to another team per the rule you mention.
However, I repeat. This doesn’t matter at all compared to Japanese players and Cuban players never have been in the amateur draft and never will be in the amateur draft. Neither are players from any other nation so that is more important in my opinion.
