IMPORTANT NOTE:
Walker Buehler is a Blue Chipper.
When he was traded, it means that Parkes had to activate him before he was traded as Blue Chippers cannot be traded.
This means that Parkes would have needed to release a player on his roster to make the activation legal and keep his team under 35 players.
From what I can see here, Parkes released 3 players after the fact, but as he acquired 3, it means he is currently running with a 36 man roster. Obviously, this will need to be fixed.
In my opinion, the trade doesn't need to be reopened; but it is important to point out what should have happened.
This hasn't come up much, so want to make everyone knows the procedure moving forward.
