Anybody know why it seems that every pitcher from Japan or Korea has a long windup that starts with them stretching their arms over their head? I've never seen any other pitcher do this than guys from east Asia. Was this just popularized by Hideo Nomo when he became the first Japanese pitcher in MLB? Most of today's pitchers would have been growing up in the mid and late 90's when he was nearly unhittable in MLB. Or is this a phenomenon that stretches back further than Nomo's career?
