Here's the latest: run scoring and hitting in general is up, but HRs are down--just the first piece of information refuting Joe P.'s recent "defense" of what a growing cadre of disillusioned statheads are calling the "take and rake" philosophy.
We'll get back to undressing Joe's argument at a later date, but suffice it to say that it's OBP that drives offense. And there are two ways to increase OBP--draw more walks or make more hits. That's what's happening in July. Run scoring is at its highest rate because BA and OBP have recovered, while HRs are still down.
It's a sign that a sizable number of hitters are setting aside the "all or nothing" approach after they watched their collective BA push itself into 1960s levels for nearly six weeks during May-June.
It's also a sign that there's a something of a starting pitcher crisis occurring this month--but not in terms of HRs allowed. No, the symptom seems to be more basic--and sabermetrically inconvenient. It appears (as shown in the table at left) that many teams' starters have suddenly become more hittable. Batting average is up, and it is strongly correlated with the often sharp rise in starting pitcher ERA thus far in July.
Sixteen teams have their starters posting July ERAs at least ten percent higher than the overall team ERA. Nineteen teams have starting pitchers who are generally more hittable in July than they've been over the course of the season to date.
(As is likely the case with most of you, we don't quite know what to do with the Tampa Bay data, since their starters are still "unto themselves." But what's clear is that the Rays are not giving up very many HRs in July, and that's how they've lowered their starters' ERA even though they are giving up more hits.) More evidence of a slow but steady adjustment from the single-minded "take and rake."
