With the Wild Card round over, it is easy to see that the long ball had an outsized impact compared to the regular season. I think the biggest hit of the Wild Card round was Austin Riley's game 1 homer, and Bohm's homer in the tenth in Game 2** was right behind it. The numbers:
75 runs scored in 9 games. 8.33 average down from 8.97 in regular season (-.66 rpg)
37 runs scored on 23 homers. 49.3% of runs, compared to 40.5% in regular season (+8.8%)
23 homers in 9 games. 2.56 per game, compared to 2.26 in regular season. (+.3 per game)
And yes, I know I am comparing 2429 games to 9, but that's the reality of the post-season. You don't get 162 games to smooth out the impact of homers, or wait for regression from either direction. If there are fewer runs per game scored, the impact of the home run is greater.
**Removing the Manfred Man in the tenth will probably make home runs have a greater impact in extra-inning games. Teams can't bunt a guy to 3rd and score on a sac fly any more.
