Major League Baseball is in negotiations with its minor league teams about efforts to "reorganize elements of the system" that could reduce the number of affiliated teams from 160 to 120, according to reports.

The current agreement between Major League Baseball and the minor league teams -- called the Professional Baseball Agreement -- expires at the end of the 2020 season. MLB is looking to make some major changes, according to reports, that would overhaul all levels of the minors, particularly at low Class A and below.

Baseball America was the first to report the proposal and detail the restructuring.
