My brother loves baseball, but I find it hard to get into and to understand. Any way you can help me with that?
Well, first it is good to have a basic understanding of baseball. It's a bat-and-ball game played between two teams. Each team takes turns fielding and batting. It's usually played in a stadium. 
Hm.. that all sounds well and good. I think I can grasp that. I'm interested so far. What else can you tell me?
So, the batting teams goal is to try and hit the ball. The person that hits the ball runs counter-clockwise around a series of four bases. Once they reach the fourth one, they score a point.
Ah, the bases part is what I've been messing up. Any other rules I need to make sure I get down?
After a player reaches a base, they are considered safe. If the fielder standing on the base touches the batter before he arrives, the batter is out.
I think I can start to make sense of all this! This is really helpful! Anything cool about the history of it?
