The Yankees starting rotation holds the third-best ERA in baseball with a 3.23 mark as a unit entering play on July 12.But they could always look to add to this group, and it sounds like they intend to do so ahead of the Nick Vannett Jersey August 2 trade deadline.One name, whos the best option available on the market, is the ace for the rebuilding Cincinnati Reds, Luis Castillo.According to MLB insider Jon Heyman of , the Yankees like Castillo, as do many teams. However, the Reds are asking general manager Brian Cashman and staff for one of their top two shortstop prospects, Anthony Volpe or Oswald Peraza.

But in the very least, Cashman and the baseball operations group are still looking around to see if they can add in an already rich area.MORE:
