When I was in Jr. High, and my brother was playing Little League, my friend Kathy and I got to keep the stats in the announcer box.
So, I can understand, for the most part, all of the baseball lingo in most baseball books. Which I think is a very good thing, because the only downside I can see to book about baseball are all the stats. For some people, that is a killer. If that is the case with you, I don't think you should avoid this book for that reason alone, because in Calico Joe, John Grisham writes as much about nostalgia, relationships and forgiveness as he does dry statistics.
I say 'dry' for the non-baseball people. To baseball people, statistics are like manna from heaven.
John Grisham writes a good story.
