The Twins like a certain profile of pitcher, that’s for sure. Someone with an elite pitch and increase the usage (Wisler, Clippard, Hill, Minaya, etc) as well as tweak the location of their fastball to be up in the zone.
That’s why I’m particularly fond of signing Jon Gray this offseason. His slider is elite, with a mid 90s fastball to go with it. If he ditched the 3rd pitch, increased usage of the slider, and tweaked his FB location, he could be a really solid value.
