Georgia high school pitching usually produces a first-round candidate or two but hasn't lived up to those standards in the past three Drafts. The best of this year's crop, Livingston has a quick arm and present and projectable velocity that could get him picked as early as the third round.
Livingston can sit at 92-94 mph and touch 96 with his fastball, though he favors a sinking two-seamer that doesn't miss as many bats as his riding four-seamer does. He hasn't had much need for it yet but flashes an effective changeup in the low 80s. The biggest concern is his inconsistent feel for spin, and he struggles to land his low-80s slider and upper-70s curveball.
At 6-foot-4 and 205 pounds, Livingston has an extremely projectable frame and some scouts believe he could throw 100 mph once he matures physically. The Georgia recruit generates velocity with arm speed and an athletic delivery that should lend itself to average control. He also offers some intriguing right-handed power and didn't crack the Hebron Christian HS (Dacula) rotation until this spring, so he could get considerably better as he gains more experience.

Georgia high school pitching usually produces a first-round candidate or two but hasn't lived up to those standards in the past three Drafts. The best of this year's crop, Livingston has a quick arm and present and projectable velocity, and that helped him go to the D-backs in the fourth round. Speaking some to his ability and his Georgia commitment, he signed for above slot at $1 million.
