That’s not how posting works. When a layer gets posted from Japan, they have 30 days to negotiate with any team in MLB they want. There’s no posting fee just to talk to the player. Teams then sign the players for whatever contract they agree to, and the team who posted him gets a piece of the contract, which has different %s based on total guaranteed money. The way you’re describing it hasn’t been done in years, for good reason.
• For Major League contracts with a total guaranteed value of $25 million or less, the release fee will be 20 percent of the total guaranteed value of the contract.
• For Major League contracts with a total guaranteed value between $25,000,001 and $50 million, the release fee will be 20 percent of the first $25 million plus 17.5 percent of the total guaranteed value exceeding $25 million.
• For Major League contracts with a total guaranteed value of $50,000,001 or more, the release fee will be 20 percent of the first $25 million plus 17.5 percent of next $25 million plus 15 percent of the total guaranteed value exceeding $50 million.
• For all Minor League contracts, the release fee will be 25 percent of the signing bonus. For Minor League contracts that contain Major League terms, a supplemental fee will be owed if the player is added to the 25-man roster.
• If a posted player signs a Major League contract that contains bonuses, salary escalators or options, a Japanese team may receive a supplemental fee equal to 15 percent of any bonus or salary escalators actually earned by the player, and/or 15 percent of any option that is exercised.
