Solid frame, more athletic than he appears at first glance; high three-quarter slot, simple, repeatable mechanics, fluid delivery, quick to the plate, occasionally falls off to the third base side; decent leg drive, above-average arm speed
60; No. 3 Starter
Low-90s offering plays up due to feel for the pitch, able to move it around the zone at will, very advanced command, projection for improvement if he focuses on pitching, holds velo well
Solid glove-side cutting action, induces weak contact; not a swing-and-miss pitch, shows potential for improvement, potential to be an average pitch
Two versions, harder one with 10-4 action, slower variant with 12-6 break and better depth; flashes solid command of both versions, feel to manipulate, room for improvement in consistency
Hard change flashes plus, might be better than the breaking ball(s); quality command of the pitch; small velo separation drives weak contact, generates some movement, commands it just off the zone as a chaser, potential plus utility
McKay came into the 2017 season as one of the top pitchers in the draft class, and he has met those lofty expectations, striking out north of 12 batters an inning as Louisville's ace. He doesn’t have raw stuff that’ll blow opposing hitters away, but the arsenal is very good and he commands it with advanced precision to outsmart hitters. He's been worked hard in college, so there are some flags there, but his floor is very high with room for plenty of projection thanks to the command profile and baseline stuff. As a top 3 potential draft selection, McKay provides security with a chance to be a top-of-the-rotation starter with additional refinement.
