The posting system (ポスティングシステム, posutingu shisutemu)[1] is a baseball player transfer system that operates between Nippon Professional Baseball (NPB) and Major League Baseball (MLB). Despite the drafting of the United States – Japanese Player Contract Agreement, unveiled in 1967 to regulate NPB players moving to MLB, problems began to arise in the late 1990s. Some NPB teams lost star players without compensation, an issue highlighted when NPB stars Hideo Nomo and Alfonso Soriano left to play in MLB after using loopholes to void their existing contracts. A further problem was that NPB players had very little negotiating power if their teams decided to deal them to MLB, as when pitcher Hideki Irabu was traded to an MLB team for which he had no desire to play. In 1998, the Agreement was rewritten to address both problems; the result was dubbed the "posting system".
Under this system, when an NPB player is "posted", his NPB team notifies the MLB Commissioner, with the posting fee based on the type of contract a player signs and its value. For minor-league contracts, the fee is a flat 25% of contract's value; for MLB contracts, the fee is based on the value of the contract that the posted player eventually signs. The player is then given 30 days to negotiate with any MLB team willing to pay the NPB team's posting fee. If the player agrees on contract terms with a team before the 30-day period has expired, the NPB team receives the posting fee from the signing MLB team as a transfer fee, and the player is free to play in MLB. If no MLB team comes to a contract agreement with the posted player, then no fee is paid, and the player's rights revert to his NPB team. The current process replaced one in which MLB held a silent auction during which MLB teams submitted sealed, uncapped bids in an attempt to win the exclusive negotiating rights with the posted player for a period of 30 days. Once the highest bidding MLB team was determined, the player could then only negotiate with that team.
Up to the end of the 2017–18 posting period, 23 NPB players had been posted using the system. Of these, 12 signed Major League contracts, four signed minor-league contracts, five were unsuccessful in attracting any MLB interest, and two could not come to a contract agreement during the 30-day negotiation period. The five highest-profile players that have been acquired by MLB teams through the posting system are Ichiro Suzuki, Daisuke Matsuzaka, Yu Darvish, Masahiro Tanaka, and Shohei Ohtani. The first three attracted high bids of $13.125 million, $51.1 million, and $51.7 million respectively. Tanaka was the first player posted under a revised procedure that was in place from 2013 to 2017; he was posted for the maximum $20 million allowed under the new rules. Ohtani was the first player posted under the current procedure; his posting fee of $20 million was grandfathered in under the previous agreement. Since its implementation the posting system has been criticized by the media and baseball insiders from both countries.
- ^ The agreement is officially called the "United States – Japanese Player Contract Agreement" (日米間選手契約に関する協定). In English, the process is most commonly referred to as the "posting system", though it is also sometimes referred to as the "posting agreement". The corresponding Japanese term is most commonly written in katakana as "ポスティングシステム", though "ポスティング制度" is sometimes used.
