Welcome to my baseball website. To start, I guess I'll explain the "Arm Side Run" name. A fastball is usually identified as a four-seam or two-seam pitch. If a pitcher has good arm side run, that means the ball will cut a bit on the arm's side of the pitcher. A two-seamer usually has arm side run, while a cutter has a good amount of glove side run.

With this blog, I'll be talking a lot about the little things in baseball. Hopefully, people can learn from this site. I doubt there will be much connection from one post to the other, but I guess that will help keep things interesting. Check back for more posts.
