Why steal against elite-armed catchers?
This is my first post (I could not find a Search function for this forum) in this forum, so please forgive me if this has already been discussed here or if I'm posting inappropriately.
Some of the elite-armed catchers have CS% of 50% or higher.
Do any of you have theories as to why runners try to steal when the CS% is below the break-even point for stealing?
Thanks in advance for any answers.

Thanks for the replay NoNameOncard -
Taking Ivan Rodriquez for example, looking at MLB-wide SB/CS in 2001, teams averaged about 0.9 steal attempts/game. Against iRod in 2001, there were 0.55 attempts/game.
By 2001 iRod had established outstanding CS% for a decade, so I assume (dangerous, I know) that teams were already saving their steal attempts for pitchers (on iRod’s team) that they thought they could steal against. That is, I assume that ‘stealing against the pitcher’ (choosing SB attempts against pitchers who were not good at holding the runner one) would already be factored into SB attempts against iRod by 2001. In other words, presumably, teams had been trying to steal against iRod’s poor-holding pitchers for several years, with roughly a 45-50% success rate. Why would they continue to try to steal against the pitcher if it wasn’t working? I’m not challenging your answer, but thinking (writing) aloud.
Re: failed Hit-and-Run, I hadn’t thought of that as contributing many CS, but then I don’t know how common Hit-and-Run is. Could it represent a significant number of CS, in your opinion? I suppose that if teams can’t steal against iRod, they’d have to try SOMETHING in those ‘need one run’ circumstances. Maybe, H&R was the answer.
Thanks again for the reply!

Missed hit-and-runs probably aren't going to be statistically significant, but...
It shows that not all CS are the result of a team thinking it can steal a base. However, for catchers like Pudge, the depressed number of overall CS-Attempts makes the hit-and-run number more significant than for someone like Pudge than for Jason Varitek – assuming an equal percentage of failed hit-and-run attempts. Again, this number may still be too small to create much of a difference.

right
A catcher’s CS% is based on his ability to throw out lots of different baserunners. If you have a very fast, high percentage baserunner who can steal on the pitcher no matter what the catcher does, it still may be worth it to send him in some situations.
It will probably be the case that Young IRod’s CS% is based on better base-stealers running than Mike Piazza’s CS%. But there still may be elite baserunners who can get a high percentage off of IRod+pitchers. Obviously, yes, on average, teams are failing in their efforts to do this. But I bet in some cases, if you had perfect information about pitchers and baserunners, there are still cases where a team should run on him.

SB attempts
hit and runs that don’t pan out are an excellent source of CSs, since the successful H&R is most useful with that hole between 1b and 2b, and there are many more RH [than LH] low power hitters who might be putting the ball on the ground rather than going for extra bases. the H&R is likely losing some of its strategic value as batters who can guarantee they will connect with a pitch are declining in the modern game, where even SSs hit 26 homers per season, but then strike out 22% of the time. baseball simulations would want to account for this trend in having the general population of MLers less able to connect than in the days of enos slaughter, leo durocher, rabbit maranville, etc. it is very difficult to determine from typical baseball stats how many outs and hits are resulting from H&R attempts and SAC grounder attempts. i see that stats inc and bill james DO have some hitting data re bunts. simulations should definitely have players rated for H&R ability, the better rated guys much less likely to swing and miss, giving the opposing catcher a potential CS. i would suggest a higher H&R rating for those with very low strikeout rates.
Thanks to you folks, I seem to have the answer to my original question, the answer being that many (most?) of those CS against catchers like Pudge are actually failed H&R.
Curt brings up a fascinating, related point about sim design.
I’ve seen two different, general approaches to Hit and Run in sims:
1. Give each batter a H&R rating on a scale of 1-3 or 1-4. The rating is presumably based on K rate. Then take a random number and look up the result on a H&R Chart.
versus
2. Calculate the batter’s result normally, as though it were not a H&R, then convert the result using a H&R chart.
My experience with approach #1 is that it can give unrealistic results, in part because such a limited number of H&R ratings clumps all batters into only 3 or 4 H&R results categories, and in part because a single H&R rating cannot adequately represent all of the aspects of hitting: K-rate, ground ball rate, drive rate, fly ball rate, HR rate, walk rate.
To give an extreme example, I’ve seen dead ball (read: low-K) mediocre batters (BA around .200) qualify for the maximum H&R rating, thereby ‘earning’ an effective H&R BA of around .350. BTW, the ‘.350’ number is not from simulation result; that number is derived from the H&R chart itself. These games’ H&R charts are typically not era-adjusted, although the stats that the players’ H&R ratings are based on are era-adjusted, of course.
Approach #2 has advantages: i. there is excellent granularity in terms of individual results; ii. individual results are not one-dimensional, but reflect all aspect of the batter’s ability; and iii. the batters’ ‘base’ abilities (before the H&R conversion) reflect their era (for example, low-hit/low-k vs high-hit/high-K, etc), then are translated to H&R results.
