His reasoning doesn't matter. Pitcher vs hitter matchups are an extremely small sample with almost no predictive ability... Yes, all that statistical analysis certainly has it's place. But Bill Hall, like other baseball players, is also a human being, sometimes human beings are actually affected by their own emotions, feelings, etc. If Bill Hall had lost confidence in his ability to hit RH pitching, that belief, itself, could adversely affect his performance against RH pitching. On the other hand, if he believed that he could hit well against certain RH pitchers, that confidence could, potentially, have helped his performance. This was the impression I had gotten from some of Macha's comments...that he was trying to put Hall in situations where he (Hall) might have more confidence in himself.
