Slender, well-proportioned frame, narrow shoulders with some slope, moderate muscle tone in upper body, could add additional strength; fluid, above-average athleticism, graceful movement; semi-wind, slight rock, moderate leg kick, low hand break, stays closed; mild stab, arm swing has some length, above-average arm speed, excellent extension with mild deception, three-quarters release will wander higher, creates strong attack angle; tall and fall, long stride, mild effort, occasional head whack; mildly inverted, closed at strike, moderate crossfire; up-tempo delivery, loses timing, struggles to get across front side and finish, inconsistent arm slot; 1.28-1.42, minimal velocity loss in the stretch
Above-average plane, boring action with mild run, occasional cutting action, stays true and flattens out when elevated, lacks life upstairs; aggressive with the pitch, established it early; 40 present command, bouts of yanking it glove-side, half-dozen hard-hit balls all up in the zone
Hard split-like action with late trap-door movement, mild fade; manipulates depth, will work it in-zone; shows feel, trusts it, will double- and triple-up, throws right-on-right, swing-and-miss potential, groundball pitch with true plus projection
Tight 11-6, two-plane action with snap, quality depth; inconsistent present execution, struggles to command, chaser frequently starts at bottom of the zone, will roll it; relatively new pitch, still raw, above-average projection with additional repetition
Johnson suffered a complicated Tommy John recovery in college leading to limited amateur innings and a 23rd round selection in 2014. He struggled to find his rhythm in this start, with an inconsistent tempo and repeatability issues dampening his command and leading to some hard contact. The arsenal is solid, with above-average sitting velocity that plays up a hair with extension and multiple secondaries that show utility. The hard changeup offers true plus projection, while the curve is further behind but moves well. Johnson's arm action and physicality both suggest potential for refinement, though the delivery has enough trouble spots that there is significant command-dependent variance still remaining in the role projection. The upside is a No. 3 starter in an average rotation.
