The major leagues schedule seven games for September 23, 1920, and play all seven, including two doubleheaders. The Browns beat the Tigers 3-0 in game two of their doubleheader for the low scoring game of the day. That completes a sweep in Detroit. The White Sox defeat the Indians 10-3 to join the Phillies 7-6 win over the Braves in game one for the highest scoring games of the day. The Phillies win the night cap as they also sweep a twin bill. Those wins break a seven game Philadelphia losing streak.
Two Phillies tie for best offensive game of the day. In game one, Cy Williams posts a four for four day with a walk and three runs scored for a Baseball Musings Game Score of 73. In the second game, Casey Stengel goes three for four with a home run and three RBI to match that game score. Williams stood out as the best hitter by far on the Phillies through this date, but Stengel had a pretty good year. Those two and teammate Irish Meusel were all in the top five in home runs for the National League.
Bill Bayne of the Browns takes home best pitched game of the day for this game two shutout. He scatters seven hits and three walks, while striking out five. Bayne is finishing on a hot streak, with a 3-1 record and 1.97 ERA in his last six appearances.
George Sisler posts a rare bad day at the plate as he goes one for six in the Browns doubleheader to drop his leauge leading batting average to .402. Tris Speaker of the Indians loses ground, however, as he goes 0 for 5 to drop his batting average to .392.
The White Sox win over the Indians closes the AL pennant race to 1/2 game, Cleveland in the lead. The idle Yankees gain 1/2 game on Cleveland, and they are now 2 1/2 games back.
There is no change in the NL race, as both the Dodgers and Giants are idle. They start a series on the 25th.
Testimony continues to leak from the Chicago grand jury investigating gambling in baseball. Rube Benton testified that Hal Chase made $40,000 betting on the 1919 World Series, and asked Benton to throw a game. Benton did not take the offer.
