April 22 - The Chicago White Sox defeat the Kansas City Athletics 20-6 at Municipal Stadium. The White Sox score 11 of those runs in a wild seventh inning in which they collect only one hit. Ray Boone and Al Smith lead off the inning by reaching on errors. Johnny Callison then collects the hit, a single that scores Boone; on the play, Smith scores and Callison reaches third on a Roger Maris error. Eight of the next nine runs score on ten bases on balls; Callison is hit by a pitch to force in the remaining run.
May 20 - The New York Yankees lose to the Detroit Tigers 13-6 at Yankee Stadium, the loss dropping the New Yorkers to last place in the American League—their first time in the cellar since May 23, 1940. The Yankees had won nine pennants over the previous ten years, as well as winning 103 games in 1954, the one year they didn't win the pennant.
May 26 - Pirates pitcher Harvey Haddix carries a perfect game into the 13th inning against the Milwaukee Braves, retiring 36 consecutive batters before Felix Mantilla reached on a Don Hoak error. Haddix would lose the game on a Joe Adcock hit (a baserunning mistake caused it to be changed from a 3-run home run to a 1-run double) later in the inning.
September 28 - September 29 - The L.A. Dodgers and Milwaukee Braves finish the NL regular schedule in a tie and the Dodgers defeat the Braves in a best-of-three playoff series 3-2 and 6-5 (12) to reach the World Series.
October 8 - The Los Angeles Dodgers defeat the Chicago White Sox, 9-3, in Game 6 of the World Series to win their second World Championship, and first since moving to Los Angeles, four games to two. The Dodgers have an 8-0 lead after 4 innings and hold on despite Ted Kluszewski's 3-run home run. The round-tripper gives the slugger a new 6-game RBI record of 10. Chicago's Chuck Essegian hits his second pinch HR to establish a new record, later equalled by Bernie Carbo of the Boston Red Sox in 1975. This was the first pennant for the White Sox in since the Black Sox scandal, 40 years earlier. It marked the first Championship for a West Coast team. It was the first ever World Series in which no pitcher for either team pitched a complete game. Dodgers P Larry Sherry was named MVP.
