10.21.17:  Lassiter is 5-10 with an athletic frame, throws from a three-quarters arm slot with a short, free arm action that is quick with normal effort. Smooth rhythm to his delivery. Shoulders are uphill and closed, swings to a square landing with a bit of a fall off finish with some recoil. Fastball was 80-81 with some late sink to it. Curveball was 66-68 with good armspeed and late sharp 11/5 break. Change-up was 75-77 with good armspeed and late run. Showed good command of all three pitches, pound the bottom of the strike zone.
