How do you get steps in flick home run for the iPod?

It is determined by how many balls are pitched to you. It has nothing to do with the score. Step 1 is the first four balls. Step 2 is 6 balls, and so on. I just counted step 7 and it is 9 balls.

Also there are 15 steps in Minor league.

I think there is more on major league but I'm not sure.Sorry
