Last Sunday, I dug a bit into Baseball Prospectus' new pitching metrics, in another effort to crack the enigmatic Nathan Eovaldi and Michael Pineda. It turned out that concepts such as pitch tunnels, command, and control did help explain some, but not all, of the frustration that Pineda and Eovaldi have caused the Yankees the past couple years.
Today, I wanted to look at the Yankees' staff through a lens introduced by BP, called "Two ways to tunnel.” Again, I encourage you to read through all of BP's new stuff, as it as interesting as it is potentially enlightening.
