alks + H
itched = WHIP
Earned Runs/IP*9 = ERA
As for BA, select the BA row or column (you can click the "A" or "1" on the outside of the sheet to select a row or column), select Format --> Cells (also ctrl + F1). Select the "number" tab, choose "number" and it'll give you an option to limitt he decimal places. You'll probably want to limit it to 3. You can also format cells to look other ways with this menu, so feel free to play around wtih it.
Hope this helps!
edit: hmm. According to your numbers that player is hitting .026, so you might have an issue with your BA calculations, too.
