2022 FUTURE GAMES: Only a 2026 grad, and more than two years younger than some of the participants, Tronstein hardly looked intimidated, but rather mirrored the elite talent present, and surpassed it in most instances. The 5-foot-10, 160-pound shortstop, who is equally as comfortable in the outfield, is an elite athlete who already produced a graceful 6.8 60-yard dash time that carries over to a quick first step on the bases and on the infield. Working side to side at shortstop with confident hands, his glove-to-hand ability stands out along with a strong arm with a quick release. The right-handed stroke is loose and athletic with the hands working fluidly down and back before triggering big bat speed with present intent to do damage. The intent, done with some controlled aggression, should get a boost of power as the frame continues filling out, but Tronstein more than declared himself as a player to know in prep scene’s newest high school class.
James Tronstein, Harvard-Westlake (CA), 2026
Positional Profile: INF/OF
Physical: 5-10, 150-pounds; Lean and athletic with some present strength throughout. 6.8 runner in the 60.
Offensively: RHH. Even setup, with feet just outside his shoulders; bat positioned at a 45 degree angle. Short take back with the hands with a toe-tap for timing. Stays behind the ball while showing a strong lower half. Showed a compact swing path with one-handed finish. More line drives than flyballs and groundballs with a peak exit velocity of 95 MPH via Trackman. Advanced hitter. Natural rhythm in swing. Present bat speed. Worked gap-to-gap with LDs throughout his round. Barrel stays in the zone a long time. Projectable power.
Defensively: INF - 81 MPH. OF - 84 MPH. Showed solid actions from both spots. In the INF showed light feet with heel-toe actions and soft hands. Fluid exchange. Above average arm strength. Changed up arm slot when needed. Aggressive feet in the OF coming in hard with his glove out front while creating good momentum to get off strong throws. Showing early ability to play both positions well in HS.
