How the pitching works:
1) Pull back all the way for the fastball.
2) Pull the trap door lever for a swing and miss sinker.
3) Pull the level back halfway for a changeup.
4) If throwing a change move a magnet under the playing surface to pull the ball either toward or away the batter. (But if the batter doesn't swing it will land in the "Ball" section.)
You can also move the fielders around a bit. If the ball hits a fielder and lands in the trough in from of them it's an out.
It even comes with a scoring book so you can keep track of all your stats.
