I understand the part about how OBP + SLG creates runs. And I agree that scoring runs is the function of an offense. I'm by no means a fan of BA as a primary measure of offensive ability. But I'm wondering if there isn't a critical point, around about the Mendoza line, where low BA starts to make high OBP or SLG hard to maintain. For example, if a hitter is batting .200, he needs an awful lot of walks to get an OBP of .400. Similarly, since BA is also a factor in slugging, a hitter batting .200 has a hard time cracking .500 SLG. He needs isolated power of .300 to get there.
Another way to put it is that while walks count once in OPS (as part of OBP), singles count twice (as part of OBP and part of SLG). That may overstate the value of the single over the walk, but singles do have both an on base value (OBP) and runner advancement value (SLG), and OPS (OBP + SLG) does seem to work pretty well as an overview of offensive ability. Moreover, a player hitting .200 or below is creating a lot of outs.
So if the Strato mechanism in an '80's context does in fact disadvantage hitters like Phelps in terms of their ability to maintain BA above a certain minimum, it might be a fact worth noting. :wink:
