I think the evidence above shows that it much better to put the first pitch of the at bat in play than the second through fifth pitches. And depending on your preference of OBP or SLG in the makeup of OPS, you could even make the argument that putting the first pitch in play is better than the second through eighth pitches (though I'm not going that far). At the ninth pitch, the OPS of .819 goes past that of the first pitch at .814. No that is not what the evidence shows. It is really not that helpful to look at those data in isolation. At best they tell only a partial picture. The likely reason the batting average is higher is because the batter was looking location and got it. That is great and all, but truely meaningful data would have to look at BA per count. I think it is pretty clear that getting behind in the count is likely to result in lower batting average then getting ahead in the count. Like everything in life context is key. With most pitchers on most nights the best tactic is to try to work the count in your favor. However, if a pitcher is constantly getting hitters into pitchers counts, then the best tactic is to be agressive early in the count. It's not an either/or thing. The Cubs, with the expection of Muton and Walker, almost never work the count in their favor.
