I've seen estimates of between 65% and 75%. What we need to keep in mind, though, is: 1. The breakeven point changes dramatically based on the base/out situation. 2. The breakeven point is based on maximizing runs. What we really care about is the probability of winning and how it is affected by a SB or CS. Early in the game, maximizing runs is a good proxy for maximizing your odds of winning, obviously. What I'd like to see is the "win probability added" (WPA) from stolen base attempts, caught stealing and pick offs for each team. That would tell us a lot more about how well the Angels were picking their spots. I am not aware of any site that offers that. Here is some team baserunning information: http://www.baseball-reference.com/leagues/NL/2010-baserunning-batting.shtml#teams_baserunning_batting::none "Stats do not tell the entire story. Sometimes you can believe your eyes and my eyes told me the Brewers were a below average offensive team in 2010 despite their impressive numbers." Aggregate stats don't but there are plenty of stats that can tell you what you are looking for. Perhaps just look at the median runs scored per game, for instance. Your eyes told you that the Brewers were a below average offensive team in 2010 but what does that even mean? Most define that as the collective team talent to score runs but your definition is different. It's you definition, so you can't be wrong but if you want to compare your opinion to others, shouldn't we be comparing apples to apples? Because of it's makeup (lot's of HRs), I have no doubt that the Brewers are someone predispositioned to get runs in bunches but I don't think the effect is nearly as dramatic as it was in 2010. It was mostly a fluke, just like the Brewer's early home record last year. Reading some of Roenicke's interviews, I like to hear him emphasizing the value of getting runners on base. I also appreciate that he completely dismisses superstitions. I am a little concerned about him possibly being too aggressive on the basepaths but there's really no way to know how he's going to manage until he actually manages. I will give him the benefit of the doubt. He may pick his spots perfectly and add a couple of wins next year. We shall see.
