I think Duran will come back. His history of success is too long. Of course, I think he is inside his own head too much, but sometimes all it takes is one hard-hit ball to make you forget a month of doing nothing.
IRT Volpe, I loved the guy coming up, but Cashman promoted him too quickly. He had a 30/8 K/W in 89 ABs. At the age of 21, he should spent at least half-season in AAA, or until he got his K/W under 2:1. But I'm convinced that Cashman thought that Volpe was the next Jeter, and maybe wanted to show the world how smart he was.
