Over the last few seasons, the Yankees farm system has improved dramatically from the days where it was mostly a barren wasteland. They seem to always have several prospects in the top 100, an ample supply of useful relievers, and young talent to keep an eye on. It's too bad that it could have been much better if the team drafted better in 2010, 2011, and 2012 because they're still paying the price now.
The 2009 MLB Draft gave the Yankees Slade Heathcott, John Ryan Murphy, Adam Warren, and even Caleb Cotham (he helped get Aroldis Chapman), who all played some kind of major league role.
