Major League Baseball will make sure Masahiro Tanaka's Japanese team, the Rakuten Golden Eagles, does not receive more than its $20MM posting fee as a result of Tanaka's departure to the US, Bill Shaikin and Dylan Hernandez of the Los Angeles Times report. That means that Tanaka cannot donate money to Rakuten.
Rakuten's president, Yozo Tachibana, had previously said that Tanaka intended to give money to Rakuten to improve its stadium. Rakuten has reportedly investigated adding a dome. Tanaka would, according to Tachibana, "cooperate and donate . . . starting with improving the environment for the players and to make sure it’s the kind of stadium that can be loved by [local] fans."
Such a donation would violate the agreement between MLB and NPB, which forbids NPB teams from receiving any money beyond a player's posting fee. "We are intent on enforcing all the provisions of the agreement," says MLB spokesperson Pat Courtney.
