LATEST PG SHOWCASE REPORT
2016 World Showcase  
Johnathan Jahn is a 2016 LHP with a 6-3 195 lb. frame from Augusta, GA who attends Westside HS. Big and strong broad shouldered build, especially strong in the lower half. Big back turn delivery with lots of moving parts, big leg raise and body curl, hides the ball and has lots of deception, has really improved over the last year and half about getting fully rotated back and directional to the plate, extended low 3/4's arm slot, repeats his mechanics better out of the windup than the stretch. Fastball topped out at 88 mph, gets on hitters sneaky quick, good arm side run and life down in the zone. Primary fastball pitcher this outing, curveball is a big sweeper with good depth and spin at times, has thrown a change up frequently in the past but did not show one this outing. Good student, signed with South Carolina.
