Johns was one of the more intriguing underclass arms in attendance, showing a projectable left-handed profile and a four-pitch mix that should continue to develop as he matures physically. The Centennial High School product worked with a fastball, curveball, slider, and changeup combination, with the slider standing out as his best offering of the day. The slider showed quality glove-side movement with depth and the ability to work off his fastball effectively. As a whole, Johns demonstrated solid feel for his arsenal, but the slider was the pitch that consistently caught attention throughout his outing. He also ran his fastball up to 79.7 mph, a notable mark for a 2028 left-hander with plenty of physical development still ahead. Standing at 6-foot, 158 pounds, Johns possesses a lean, projectable frame with room to continue adding strength. As that physical development comes, there is reason to believe additional velocity could follow. While the current profile may project more toward a relief role, the combination of a quality breaking ball, present velocity, and future projection gives him a chance to continue developing into a starter profile. Overall, it was another encouraging look at a young left-hander with upside.
