In my, admittedly limited, experience in ATG, HAL does an OK job of dealing with pitchers. I don't recall seeing a double-switch, unless both players were pinch hit for in the same inning.
As always, there were times when you felt he should have pinch hit and others when you thought he shouldn't have.
I'm with Wineman, the fewer decisions Hal has to make the better. At least, that's our preference.
