Uncommitted. Strong 6-foot-1, 195-pound with more room for added strength and fill to his frame. Johnson lifted the ball consistently during his round of BP showing feel to drive the baseball in the air. At the plate, the right-hander starts wide, with a high leg kick that allows him to get into his legs before delivering a strong barrel to impact the baseball. Defensively Johnson plays with some bounce in the infield, with a pair of steady hands with some arm strength up to 84 mph across the diamond.

INF Jameson Johnson (Pecatonica, 2024) stood out to our scouting staff over the weekend with a quality showing overall. Listed at an athletic 6-foot, 180-pounds, Johnson still shows some room for added strength throughout his frame. At the plate, the right-handed hitter uses a minimal hand load to start his operation, moving through the zone quickly with bat-speed and an uphill path. He stayed on the barrel throughout his round, reaching up to 90.5 mph with mostly line-drives.
Johnson is listed at 6-foot, 175 pounds with a proportional frame that has room for additional strength and muscle gain. During batting practice, Johnson displayed a line-drive approach with a handsy swing that helps him drive the baseball to all fields. Defensively, Johnson showcased athletic actions, fielding through the baseball, also displaying the ability to make throws from multiple arm slots.
