Exactly. And distraction does not always translate to tangible results. And from what we know, more often then not it does not translate to anything. What we have is conventional wisdome based on a logical belief but nothing that supports that it is so. For a guy to even make it to the majors he would have to be able to handle such situations with some level of success. A good baserunner will lul the pitcher into to thinking he is not going almost making him more comfortable. It is much easier to steal with a normal stretch then a slide step.kl;j the bolded part above is actually a bit of wisdom based on a logical belief but with nothing that supports that it is so, too. the entire notion that the minor league process weeds out those who are worse under pressure, is expected to be accepted, without any scientific evidence of whether this is or is not true. some how we are just supposed to accept that baseball players are different than every other profession in the world because there is a minor league process. there are people who have reached the top of every profession even though they don't perform well under pressure because they are extremely talented overall, but somehow baseball's minor leagues operate differently than the weeding out process in every other profession. I think we see evidence of some attrition by the stats guys in this area. Bill James admitted that there were problems with the way they were trying to measure clutch. and despite the notion that any good pitcher will be a good closer, we saw Depodesta give Gagne a huge contract, Epstein give Foulke a huge contract, and Beane trading for a proven closer three years in a row. I look at it this way. pitching is an activity of intense concentration. there is so much to think about in terms of what is the best pitch to throw in a given situation and it takes tremendous concentration to execute that pitch mechanically. anything that contributes to breaking some of that concentration is going to cause more mistakes and lead to better opportunities for the batter. a fast baserunner may not always result in tangible results in terms of better opportunities for the hitter, but it will rarely if ever result in worse opportunities. a lulled and therefore comfortable pitcher is presumably not a better pitcher. thus, the net effect will be a net gain in improved opportunities for the hitter. If the bolded part results in something tangible more often then not (i.e. an earned run or run scored) then the guy never gets out of low A ball unless no one ever gets on base. A guy like Greg Maddux is the case in point. He has never worried about guys stealing on him. Why is that? He gets the next guy out.
