I didn’t pull waiver back.
I let him go to gain cap space and roster spot
A's will drop RP Tyler Duffey P-2018 $0.5M to make room for SP Lance Lynn $3M and pay cash $1M to Red Sox on waiver trade.
In reviewing this transaction, although Oakland wants to give Boston a $1.0m cash exchange for relinquishing the Lynn contract, such a transaction is not allowed because we do not allow cash to be traded unless it is tied to player. If Oakland had acquired Lynn as a part of a trade and traded a player to Boston, the cash exchange would have been allowed. But since it was simply relinquishing the contract through waivers, no cash exchange can be made.
As the Boston GM clearly states, he "let him go to gain cap space and roster spot", this is not a trade, it is a waiver transaction.
Sorry for the confusion.
