Fastball

56.1% Thrown  92.0 MPH

Despite its crazy good movement and unreal ability to generate groundballs, Tyson's Two-Seamer returned a very negative -8.8 RAA value in 2015 due to its wild nature - it allowed a staggering 13.5% walk rate in 2015. But man, I could watch this GIF for days.

Slider

44.0% Thrown  85.1 MPH

Ross' Slider is one of the deadliest of its kind in the majors, and allows him to dance around his horrific walk rate as it has featured a 21%+ whiff rate for three straight seasons.
