ZiPS KBO Update: Dinos No Fluke, Eagles Have (Crash) Landed
Back before the Korean Baseball Organization’s Opening Day, I altered the methodology ZiPS uses to project Major League Baseball standings to do the same for the KBO’s 144-game season, as it was nearly the only game in town for viewers in the United States. Because projections aren’t written in stone, and are constantly in flux as actual on-field performance eviscerates old projections, I also update the ZiPS’ in-season methodology. After all, ZiPS is a large set of algorithms, not a time machine; the future never exactly matches the prognostications.
One interesting note is that offense has shot way up in the KBO in 2020. After dejuicing the baseballs for 2019, the league’s ERA dropped from 5.17 in 2018 to 4.17 last year. Nearly a third of the way through this season, that ERA is back up to 4.80, almost entirely due to a bit of a re-explosion of home runs. As far as I know, they haven’t re-juiced the baseball, so it will be interesting to see if this keeps up, and if so, do we see similar results in Nippon Professional Baseball or MLB, possibly as a result of pitchers having less time to prepare for the season?
But enough of that; let’s get to the updated projections.
