Easy training points - When you are a pitcher in Road To The Show mode, a good way to get extra training points is to catch every possible pop up you can reach on the infield. One out is worth 5 points, two outs are worth 10 points, three outs are worth 15 points, and it goes up. Make sure you can easily reach the pop up. If you get to the ball at the same time it is about to reach the infielder who is calling for the pop up, it may fall in.
