No two ABs are the same. Every pitcher-batter matchup is going to have different dynamics. Maybe Hairston just sucks at identifying/hitting the kind of pitches that most pitchers throw in those situations. You are inferring things I did not say, and your approach to the subject is unscientific (but your bias makes you *think* it's scientific).
I don't have any interest in this debate because it has no resolution. The difference between us is that I realize it has no resolution, whereas you unequivocally believe you know the answer.
Eh, I wouldn't go that far... I wouldn't eliminate the possibility that he somehow does worse in those situations, but on a larger scale, the situation rarely affects the at-bat. Your suggestion, which I understand you are proferring as a possibility and not an assertion, that he struggles to identify certain pitches, is vague at best.
What I believe is that it's highly unlikely that he actually performs worse in those situations and it is much more likely that it is a sample-size fluke.
