Now that Manfred has agreed to the universal DH, Logan Webb has officially hit the last home run by a pitcher in the major leagues, which he did against San Diego on the last day of the year.  Shades of Madison Bumgarner.

Hey Mick, in general, how has the DH affected pitching stats? Intuitively it would seem that ERAs, for one, would be higher.

You can't just compare raw AL and NL run scoring statistics because of the different parks, but in general the delta from having a DH is understood to be between 0.1 and 0.2 runs per team per game. Last five seasons the overall ERA in the AL (going backwards) was 4.32, 4.42, 4.60, 4.27 and 4.37 and in the NL was 4.20, 4.47, 4.38, 4.02 and 4.34, i.e. deltas of 0.08, 0.13, 0.22, 0.20 and 0.03.

Hmmm.  It would seem a better comparison might be just within the AL, pre-DH vs with DH.  Or maybe not -- as the lowering of the mound is probably in there, along with the so-called "livelier ball."
