Gonsalves burst onto the draft scene last spring, showcasing his talent with an outstanding performance in the CIF San Diego Section Division III championship game, where he went the distance, striking out eight and picking up his 10th victory. For the season, the lefty went 10-0 with 79 strikeouts in 66 innings.

He flew high all summer, putting on a couple of impressive performances on the showcase circuit. He further solidified his stock with a strong performance this spring, leading off with a sterling outing against Grayson High (Ga.) and fellow top prospect Austin Meadows in late March at the National High School Invitational.


Full Scouting Report

Note: Numerical scores are on the conventional 80-point scouting scale, with the current score first and projected score second.


Considering his lanky frame, Gonsalves is an exceptional athlete. When he's not on the mound, he's usually stationed in the outfield, where he's shown good range and speed. Managed to leg out a triple in the National High School Invitational matchup against Grayson HS. Good mechanics for such a big guy, but will have to be vigilant as he puts on more weight. Has great balance. The ball explodes out of his hand and gets on top of hitters really fast. Strange quick of separating the ball from his glove before he goes into his windup.

Fastball: 55/65

Velocity isn't what one would expect from a pitcher his size; fastball usually sits in the 88-93 range; can occasionally reach back for 94 mph; idea is that Gonsalves will gain velocity as he packs on the pounds and develops physically; commands his fastball really well; not much movement on the pitch; admittedly throws fastball 80-90 percent of the time; if he can squeeze a few more mph out of the pitch, it should grade out as an above average offering.


Curveball: 40/55

Curveball is clearly his third option right now; velocity on the pitch sits 78-83 mph; has shown a good breaking curve, but has shown little-to-no consistency with the pitch; bottom line is he doesn't use it enough to warrant a higher grade; with more use and great development of the pitch, it could turn out as a slightly above average offering.


Changeup: 50/60

Rarely throws changeup, but when he does he shows great feel for the pitch; like his curveball he needs more experience throwing the pitch to make it usable at the next level; should eventually grade out as a better offering than curveball.


Control: 50/60

Gets high grades for control of his fastball; changeup and curveball control is holding him back, but improved control should come with more experience throwing both pitches; always have to worry about bigger guys and their control.


Command: 45/55

Once again, command of his fastball is a definite plus; command of curveball is spotty and inconsistent at best; not able to throw changeup where he wants to in strike zone either; needs much more polish on both off-speed offerings to survive as a starter at the next level.


MLB Player Comparison: Madison Bumgarner


Projection: No. 4 or 5 starter on first-division team


MLB ETA: 2019


Chances of Signing: 55%

The odds of Gonsalves honoring his commitment to the University of San Diego are a lot higher than they were seven or eight months ago. Back then he was arguably the top left-handed pitcher in the 2013 class. He's slipped down draft boards now, so it might make more sense to head to USD, pack on some pounds, boost his velocity and try again in three years. He could have top-10 pick potential then.
