The Cuban regime will collect big bucks in “signing rights fees” from MLB, just as the Japanese and Korean leagues do.
Yes, the structure of the agreement is very similar. Players get posted, then the MLB teams bid on them, and the club (in the case of Japan and Korea) or the CBF (in the case of the Cubans) gets a fee that amounts to a percentage of the amount that the player is paid by the MLB club.
Take Yusei Kikuchi, the currently posted Japanese lefthander from the Seibu Lions (27 years old.) I don’t know where he’ll sign, but for purposes of argument, let’s say it’s the Yankees. The Yankees would then pay Seibu a percentage of the amount they pay Kikuchi.
The only difference is that with the Cubans, instead of paying the Havana club of the Cienfuegos club, it’s the Cuban Baseball Federation. Technically, the CBF isn’t the government, but of course it actually is.
