This is the easiest way!!! Create interrupt save data when you start to bat. If you get an out, then hit
and select quit to title screen. Then just click back into the original game to resume where you left off. After EVERY hit or homer, create another backup save. Wash, rinse, and repeat until you have 10 runs. This saves so much time than having to deal with being lucky against the A.I. pitching without saving.
