Query: Great for young baseball lovers

I bought this for my son's fourth birthday last year. He loves baseball and I thought this would be a book that was both entertaining and educational.He loved it. We read it everynight for about two weeks and he began to understand what the different positions and rules were.It is a year later and we still read it occassionally just for the fun of it.
