Just finished reading "Money Ball". Very interesting take on stealing bases in the Pros by Billie Bean GM of the Oakland A's. At the Major League level, where the players are more likely to make the plays, Billie Bean believes that you don't steal unless it is almost a sure thing. His philosphy is that you only get 3 outs an inning and 27 per regulation game, so an out is too precious to risk with a steal (unless you are almost certain it will be successful) when the next batter may get a PB/WP, E, D3S, HBP, BB, 1B, 2B, 3B, or H to move the runner over.
Now his take on the SAC bunt is even more extreme. Basically you don't as statistics have shown the SAC bunt is a waste of an out except in special situations! In the book they told about the A's Manager asking one of his players why he bunted a player over when he, the Manager, had not called for it and then had the player advise the press that the player had done that on his own so Billie Bean wouldn't jump the Manager.
An interesting book that presents an interesting philosphy about managing and building a team that appears to be slowly spreading to a few of the other MLB teams.
