If the runners advanced on a thurd ball, even by mistakes, I would think that you could score them as a stolen base. Especially in fastpitch, my sport, there are lots of crazy base stealing opportunities outside of a straight steal (drop third strike comes to mind). On the umpires getting it "right"...

jdale,
I would suggest that you check out the individual games. They can be associated with a league as well.
1) Set your league to ALL
2) Do you see the 6 games? You should at that point.
3) Select the games you didn't see in the team stats, verify the league for those games.
Hope this helps.
