We just finished up the 1920 regular season of the No Whining Progressive Random Edition, and the final days of the regular season were incredible.
With 5 games to play, the standings looked like this:
National League Standings
American League Standings
Note Detroit's run differential of +390...rarefied air...in real MLB only the 1939 Yankees have ever exceeded that.
The schedule makers must have been prescient, because the final 5 game series in each league had the contenders going head to head...Boston visiting St. Louis and Detroit in Chicago.
Would you believe that after 3 games, both races we're still in play? The 2nd place teams each swept the first 3 (odd of this happening, assuming the teams were evenly matched: 1 in 64). The standings after G160 were:
National League Standings
American League Standings
Note that Detroit was now +409 in run differential.
In game 161, Chicago finally clinched with a nail-biting 1-0 victory, but St. Louis won AGAIN and the NL was in a flat-footed tie:
