I dunno why Girardi has this reputation of working in young players. With the Marlins, he had no choice. That's all they had. With the Yankees, young players constantly rode the bench & barring some injury to the veteran blocking them, they stayed on the bench. Dellin Betances is one of their top relief prospects & since being called up September 1st, he pitched 5 innings, most of which was when they were already eliminated from the playoffs 4 weeks after being called up. No thanks to Girardi.
