10.07 Stolen Bases And Caught Stealing

(g) The official scorer shall not score a stolen base when a runner advances solely because of the defensive team’s indifference to the runner’s advance. The official scorer shall score such a play as a fielder’s choice.

Rule 10.07(g) Comment: The scorer shall consider, in judging whether the defensive team has been indifferent to a runner’s advance, the totality of the circumstances, including the inning and score of the game, whether the defensive team had held the runner on base, whether the pitcher had made any pickoff attempts on that runner before the runner’s advance, whether the fielder ordinarily expected to cover the base to which the runner advanced made a move to cover such base, whether the defensive team had a legitimate strategic motive to not contest the runner’s advance or whether the defensive team might be trying impermissibly to deny the runner credit for a stolen base.

What a noble thought.  Scoring baseball is, I think, the task I am probably most perfectly suited to do.  The Major League Baseball rule book
