Possible correlation : Boston at 43 wins matches 2 other teams (Cubs,Guardians) and trail 6 others (NYY, Rays,Braves, Dodgers,Astros, Twins)in wins. So over a large enough sample (1/2 season) runs scored correlate to wins. Shouldn't be surprising.
One team that did not get a hangover from losing the WS to the red Sox are the Dodgers with best record in MLB at 54-26.
