Meanwhile, in the land of homeostatic homeritis, the August numbers are within moments of being final and official. Warmer weather propped batting average up a bit (.253), and HR/G rose slightly as compared with July (1.19 vs. 1.15), but a decline in walks (2.99/game as opposed to 3.26 in July) contributed to a slight decline in run scoring (4.46 per team per game as opposed to 4.7 for July).
When we say homeostatic, we mean it: the HR/G ratios for this year might be the most consistent across the months as any we've seen: 1.09 in April, 1.17 in May, 1.16 in June, 1.15 in July, 1.19 in August.
The last year the STDEV for HR/G by month was this low was in 2010. Such lack of volatility is actually pretty rare. The least volatile year for HR/G fluctuation was, of all years, the strike season in 1981.
Here is the vital sign comp chart updated through August 30 [at right], measured in percentage change from the 2018 month in question to its 2017 counterpart.
In case you're wondering, September has tended to produce HR/G at a 5% lower rate than the overall yearly average over the 2000-2017 time frame. That would suggest that the September HR/G rate will clock in at around 1.09.
