Bring up the Stats report you want to change (Batting, Pitching or Fielding).

When the report displays on the screen, click Format.
Click Change.
**If there is no report listed in Reports area and Add is the only option available under Format, click Add then click the Default button on the next screen. You will now see Report 1 in the reports area. Click Change.***
The Report Line box shows the list of stats that will show on the report, while the Not On Report box shows the stats not displayed on the report.
Move stats onto the report by selecting them on the Left Side(Not On Report) and using the arrow button to move them over to the Right Side(Report Line). A stat will be placed onto the report line ahead(above) the stat that is highlighted in the Report Line box. Therefore, if you want a stat to get listed on your report in a certain order on a report, highlight the stat that it will come before in the Report Line box and then use the arrows to move it from the Not on Report box to that position. If you place a stat on the report line and it is not in the order you want, you can click and hold on that stat then drag it up or down in the box to place it correctly. Stats can also be moved off the Report Line by using the left pointing arrows to move them to not on report.
Do this for the stats you have created.
Click OK
Click OK again.
The preview should show the updated report.

I hope this helps.
