Who pays Major League Baseball players salaries?

The maximum a first year minor leaguer can make is $1,100 a month. After the first year, there is no monthly maximum so the player could make more. All contracts are negotiated by the major league team. The minor league team is responsible for operational expenses but not for contract expenses.

A minor leaguer player does make good money but major leaguers make way more!!

A first year player will make approx. $850 a month, then each year earn a raise. If a player moves up in the organization then a new contract is purchased and the salary increase. Minor Leaguers don't make good money till at least AA level. This is the reason that players whom get drafted ask for a larger signing bonus to make things easier month to month. AAA Players make good money. AAA contracts get a much higher salary. A Major league contract has a minimum salary of approx. 750K. All Contracts are the property of the organization and get really complicated based on performance and experience.
