INF Jacob Jelinek (St. Ignatius, 2026) stands at 5-foot-11, 160-pounds and has all sorts of room for added strength in his projectable frame. The right-handed hitter gives off a confident presence in the box with a hitterish look; crouched and athletic setup, hangs foot into a controlled stride, hands work loosely through the zone with extension out front. Works deep into counts and has a good feel for the strike zone, rarely chasing and staying selective. Expect more power as he continues to fill out.

Quality defender up the middle with soft hands and fluid feet, showed some range to both sides of his glove.
