@knuckleman_37 impresses Charlie Hough! The lefty flew in from Seoul, South Korea, for the 2026 Charlie Hough Knuckleball Clinic. He spent seven years pitching in the KBO with a 90 mile-per-hour fastball before injuring his elbow which required Tommy John surgery. He then turned to the knuckleball. His top velocity for the knuck is 78 mph, but Charlie slows him down to talk about hand position and feel. #knuckleball #knuckleballnation #knuckleballmechanics #너클볼 #ナックルボール | Knuckleball Nation
