The Las Vegas 51s Professional Baseball team is owned and operated by the Stevens Baseball Group.
The New York Mets Major League Baseball team is owned and operated by Fred Wilpon and his Sterling Equities partners.
Minor League Teams are then directly "affiliated" with one Major League team through a standardized Player Development Contract (PDC).
Minor and Major League teams may enter into a PDC for a two-or four-year term and may reaffiliate at the expiration of a PDC term.
The purpose of the PDC is to develop players available to play in the Major Leagues on demand.
The manager, coaching staff, athletic trainer, strength coach and players of the Triple-A affiliate are employed by the Major League affiliate through the PDC. (Las Vegas 51s manager, coaching staff and players are employed by the New York Mets, beginning in the 2013 season).
There is a total of 30 Triple-A cities that comprise the 14-team International League and the 16-team Pacific Coast League...therefore the 30 Major League teams have PDC's with the 30 Triple-A teams.
