In my save I received news of a trade between the A's and the Pirates. Only trouble is that the Pirates dealt Oakland a player they had just drafted two months earlier, which is against MLB rules, and I know this is enforced in the game because when I've tried to trade for certain prospects I've received the message "the player cannot be traded as he was drafted less than a year ago".
This may have happened several times before but it caught my eye this time because the story referred to a 17-year-old as part of the deal.
