A stolen base is credited to a runner when he advances a base without the aid of
a base hit, a putout, a fielding error, a wild pitch, or a passed ball. If a runner
is attempting to steal as the pitch is thrown, and the catcher does not
control the pitch, it should be scored as a stolen pass, not a wild pitch or
passed ball.
Exceptions - The runner is not credited with a stolen base if:
- After reaching the base, the runner overslides the base and is put out
- In an attempted double or triple steal, any runner is put out
- The runner advances solely because of a defensive team's indifference.
This should be scored as a fielder's choice.
