Here are updated values for the run scoring levels (R/G), homers (HR/G) and walks (BB/G) in the first three months of the 2018 season as compared with the monthly figures in 2017. They are expressed in percentages (higher or lower).
As you can see, the figures for this June (as we approach the halfway point for the month) show an ongoing downturn that now register safely in double digits for R and HR. (The current HR/G rate for June 2018--1.15--is slightly lower than the rate in May--1.17--which is a reversal of the usual trend.)
Of course, last June produced the highest monthly HR/G rate in baseball history (1.35), so there is ample room for decline. The current rate in June 2018 is still the
fifth highest HR/G rate for all months of June and ranks in the top 30 for all monthly HR/G averages.
