A few years ago, the Yankees had one of the best farm systems in Major League Baseball. They had guys who were just on the cusp like Severino, Sanchez, Judge, Andujar, Gleyber. They were all in the system or well on their way to the big leagues.
The Yankees have won a lot of games the last few years, so no one has really noticed that the farm system has kind of taken a step back. That is definitely ok though. The point is to have a strong MLB team while using the farm system to supplement that, either via trade or call up.
