wOBAcon
I can’t see the charts at the office, but I presume there’s some interesting stuff in there.
Note that the denominator should be BIP, not PA, though I presume that was just an oversight in the description.
You can think of wOBAcon as something between batting average and SLG, for contacted balls. I’m sure a few of you have seen batting average after removing strikeouts. And by the same token, you can have SLG after removing strikeouts. Whereas batting average treats each hit the same ("1"), SLG tries to give it a better weight (1,2,3,4). The problem is that they are both too extreme.
If you simply did 55% batting average (sans K) and 35% SLG (sans K), you’d get just about exactly wOBAcon.
(Note: SF would count in the denominator.)
I am greatly disappointed that wOBAcon is just another stat.
I saw the headline, and figured that is one convention I need to try and attend. Maybe somebody else with more initiative will get the same idea and make it wOBAcon happen.
