Is there a way that I can change the player lineup for different inning? I'm still new to this,lol, maybe there is?

Not sure what you mean by changing the player lineup for different innings. Are you talking about entering subs? The training video at http://iscoresports.com/baseball/training.php" onclick="window.open(this.href);return false; covers substitutions.

or perhaps preset fielders?

options menu from game lineup screen before game starts.
