While the stalled development of several heralded prospects has hurt the Yankees in recent years, new names are emerging. Right-hander Luis Severino and shortstop Jorge Mateo highlight New York's aggressive pursuit of talent in Latin America, while first-round picks Aaron Judge, Ian Clarkin and Eric Jagielo all came from what could be a very productive 2013 First-Year Player Draft.
When catcher Gary Sanchez and outfielders Tyler Austin, Slade Heathcott and Mason Williams teamed up at high Class A Tampa in 2012, they looked like they'd form the core of the Yanks' lineup two or three years down the road. But injuries have impeded Austin and Heathcott, while inconsistent production and effort have slowed Sanchez and Williams, forcing New York to continue to tap the free-agent market.
How much has the stock of the once fab four fallen? On MLBPipeline.com's new Yankees Top 30 Prospects list, Sanchez checks in at No. 7 (down from No. 1 a year ago at this time), Austin at No. 18 (down from No. 6) and Williams at No. 27 (down from No. 2), with Heathcott unable to make the cut (after ranking No. 3 a year earlier).
