On the 09/04/2005 Ritsuko and I went along to watch our nephews play base ball (they are numbers 8 and 10 in the Navy Blue).
I was amazed at the "professionalism" that there was even in a primary/elementary school team, the uniforms were very authentic, the mannerisms of the players were like US major league players (well our nephews spend most of their time watching US major league games on TV and I suppose the other players do), and they played real hardball not softball or teeball (like kids their age in Australia do).
