While waiting for the NL playoff to be completed, the Red Sox tune up by playing a team of American League All Stars. In the 5th, Senator P Mickey Haefner accidentally hits Ted Williams on the right elbow with a pitch. The injury will affect Williams' play in the World Series.
Johnny Neun is named the Reds manager for next year.

The Yankees send veteran Joe Gordon and Ed Bockman to Cleveland for 32-year-old pitcher Allie Reynolds (11–15). Columnist Dan Daniel will later report that Larry MacPhail and Bucky Harris initially wanted Red Embree, but DiMaggio advised them to take Reynolds.

IN THE NEWS: Enos Slaughter sprints all the way from 1B and slides into home with the winning run in the 8th inning on Harry Walker's double, as the Cardinals edge the Boston Red Sox 4–3, giving St. Louis the World Series four games to 3. Harry Brecheen wins three games for the Cardinals, including Games six and 7, the only pitcher ever to win those. Billed as the duel between the two best hitters in baseball, the Series sees Stan Musial go 6-for-27 and Ted Williams 5-for-25. With the Series held in two small ballparks and the broadcast fees now aimed at a player pension fund, the Cardinal share of $3,748 and the Red Sox portion of $2,140 is the smallest Series payoff since 1918.
