Abel on 1st, Baker batting with 2 strikes. Abel off with the pitch, Baker strikes out. Throw from the catcher is wild and Abel ends up on third. I know it's a K, SB (Abel to 2nd) and Error (Abel to 3rd); the question is in the proper scoring sequence.

I did the following:
Tap Abel, Stole next base
Tap Strike, select "Strikeout Swinging" in the dialog box
What happened to Abel? Safe at 3rd, Error, 2, Throwing

Since I can only enter one "action" for Abel on Baker's K (i.e. I can't enter a SB then an E), I did the SB immediately before it.
Is that correct? Any other suggestions?

That probably works. It has to be done in two sequences.

I would do:

Strike, swinging.
What happened to runner? safe, second, sb
Then tap runner, safe, third, error, 2.
