McKenzie Mills LHP Hagerstown Suns (Evaluated 4/26/17)
Fastball (45/50+) Slider (30/30) Changeup (35/45) Curveball (30/40)
Prototypical pitchers’ frame standing 6-4 205lbs, Mills is an obvious athlete with potential to add 10-20lbs in the future. Utilizes a tradition 3/4s arm slot, near 90 degree angle at the elbow. Pitches both from the windup and stretch – windup uses a simple one-step and rock delivery into a medium to high leg lift. Has a tendency at leg lift to lean toward second base, which hinders his balance and ability to repeat his mechanics. Command also wavers due to this mechanical flaw – looks potentially correctable with repetition.
4-pitch arsenal – Fastball (89-92mph, T94 1x) shows cutting action in on right-handers and occasional late life, struggles to command especially arm-side – Inconsistent but intriguing left-handed heater. Slider (75-77mph) thrown a few times, slurvy and looked like a faster curveball. Curveball (69-73mph) showed poor shape, rather loopy and lacks tight spin, slows arm speed; will throw for strikes. Changeup (75-77mph) has promise, replicates arm speed relatively well, will show sink and occasional cutting action. Easily his best secondary pitch but needs development to improve consistency.
Overslot 18th round pick in 2015 ($150,000), this 21.5 y/o has a tremendous physique and a left-handed arm that can reach the mid-90s. However, his inability to repeat his mechanics and struggles to spin a breaking ball limits his profile and eventual ceiling. Interesting arm but unless off-speed pitches take a significant step forward, likely to stagnate in the upper minors.
