Pitch Type Present Grade Future Grade Sitting Velocity Peak Velocity Report
Fastball 50 60 90-92 93 Easy velocity, sharp arm side run; movement flattens out up in the strike zone. At present command is below average. Shows ability to throw good strikes but he can lose the release point and miss to both sides of the plate. Given size there's reason to believe there's more velocity in the arm.
Curveball 45 60 75-78 79 Sharp 11-5 movement with a tight break. Pitch is very effective in the lower half of the zone. Present command is below average. Isn’t consistent with staying on top of the pitch, command drifts, misses north and south. Has bat missing potential, command needs to be tightened up.
Split Change 40 50 82-83 84 Didn’t go to the pitch much, lacks confidence and feel for the pitch. Misses up with the offering, doesn’t finish it. Movement flashes plus with downward tumble.
Overall

Mejia is a raw product with a long development path. The tools are loud, the fastball and sharp curve are a solid base to start with and the split change flashes potential. There’s risk in the profile; he has a limited professional resume, he threw a total of 49 innings in rookie ball last year and will be making a big jump to full season ball this year. There’s 3 starter potential; While I’m wary of pitchers learning the split this early in the developmental curve the offering flashes plus potential. Even if a third doesn’t come around the arm can work in a relief role as a fallback.
