Thanks largely to the trade deadline, the Yankees improved the depth and quality of their farm system substantially over the last six months or so. They added a dozen prospects at the deadline and two more in the recent Brian McCann deal. It sure feels like another trade is inevitable (Brett Gardner?), so chances are more prospects are on the way.
The Yankees also added to their farm system this summer with the annual amateur draft. This year they held a top 20 pick for the second straight year after having only two top 20 picks total from 1994-2014.
