Today's highlighted entry is:

1921
In the first one-city World Series since 1906, the Polo Grounds will be the site for all nine games. Carl Mays (27-9) is at his best, needing 86 pitches to set the Giants down with five hits—4 of them by Frank Frisch. Ruth drives in the first run of the Series in the opening inning of this 3–0 Yankee win. Mike McNally, subbing for Frank Baker at 3B, steals home in the 5th while Phil Douglas (15-10) is winding up. The game is broadcast on KDKA radio, with Grantland Rice announcing. It is the only game of the season's World Series to be aired.

Only one game was on the radio? And it was a Pittsburgh radio station?
