If you press A and the directoin of the base you are going to throw to right after the computer catches the ball you will have a harder throw. To get auto batting aim just use rookie difficulty and slightly move the analog stick.
To get your cursor to follow your ball automatically, Hold your analog stick a little off center(in any direction) and the cursor will automatically follow the ball as it's being pitched. This makes things a lot easier. It's just one more thing you won't have to worry about when you're at bat.
When you create a player you can only use a certain amount points to strengthen different skills. These points can be raised throughout the season. Create your player then sign him to a team. Throughout the season release him into the free agent list. Then go back into "create player" and you'll gradually recieve points to be added on. Continue this througout the season and you'll make the best player with full points on every skill.
