Extremely athletic, fluid delivery, tilt/pause gives deception; gets extension and plane, balanced; mild stab, high-three-quarters arm slot, outstanding arm speed; ability to finish out front, strong, mature lower half, some room to fill out upper body and possibly grow; height not an issue
Gets impressive downhill plane; plays up with plus life, plus run with sink at times, tails into zone, effort at 97 is as leisurely as lower sitting velo; can regularly hit 97; already works both sides, attacks, not afraid to get aggressive and challenge inside; can reach back for elite velocity, confirmed reports up to 99; keeps it on a leash (92-94) early in games; low 4 FB command mainly due to inconsistent finish out front; prone to leaving it center-cut, leading to hard contact, causing the plus-plus raw offering to play down.
Strike-throwing ability present at 18 years old with projection for additional velocity, athleticism and fluid motion suggests further advances in command given age; will use higher end velocity as he moves up levels.
Big velo separation; downhill with plus fade and serious tumble; replicates arm speed; natural deception from motion; can get firm and on top of it; flashed 60+ repeatedly but inconsistent offering at present; can dream on grip consistency, arm speed, athleticism, and deception; advanced feel for the pitch, long fingers; innate feel for pitch; already flashes as a legitimate major-league out pitch.
Effortless ability to spin it in warmups, natural pitch; 11-5 break from high-three-quarters slot; tight spin, does not roll; shape still evolving, some show true 11-5, others feature more horizontal movement and tilt; very good depth, inconsistent and will get around it and overthrow at present, developing approach, attempting to work backwards with the pitch; flashed plus multiple times in first viewing; can spot it low and away to right-handed hitters, chase pitch; occasional out-of-zone command.
Espinoza combines pure athletic projection and advanced feel, all while at the age of a current high school senior. He shows the characteristics of a starter, with distinct routines and a slow heartbeat, and projects remarkable poise, remaining unfazed by performance adversity and the twists and turns of a game. The floor for the command looks to be average, and he already demonstrates an advanced feel for pitching, along with the ability to make adjustments between and during starts. He also has a plus glove/range and can hold runners. It's an unmatched combination of repertoire and athleticism at age and level, with an elite fastball and both secondaries projecting to plus or better with experience and reps. This is a front-line, first-division starter future with makeup to complement the pure projection; he shows everything you want to see in an elite pitching prospect at a remarkably young age.
