Right now MLB.com has up a 5 part series on baseball in the Dominican Republic that shows how things are for kids growing up to the point when they sign with a team and get to play in the Dominican Summer League.
Go to www.reds.com and in the flash menu that scrolls different stories is the Beisbol Dominicano: Training at the Academy story and gives you a chance to watch all 5 parts. Each part is four to five minutes long and its really a great piece that gives you an insight into things that you may not have known before.
