If pitchers get distracted, then why did the person following Pierre perform worse when Pierre was on base more? Apparently, Castillo's not good @ hitting w/ a guy on first. Small sample size considering the many, many speedy leadoff men who have played baseball... And yet a very sizable sample for the exact individual we're talking about. Can we see the effects from some of these other speedy leadoff men? There was an article on Hardballtimes.com on Feb 6 that talks of this. There is also a link looking at basestealers and effect on the #2 batter at the bottom of the article. It is interesting to think about. The link showed with no outs the batter is helped quite a bit for 40+ basestealer and as the outs go up the effect is smaller. Anyway enjoy http://www.retrosheet.org/Research/PankinM/sabr32.pdf That makes a lot of sense, actually. You'd figure with two out and a man on first (be he Marke Grace or Rickey Henderson) that the picther would be more likely to concentrate on the batter. By contrast, with no one out and Rickey on first, the picther is more apt to be distracted. That's reasonable.
