The 1947 major league baseball season began on April 15, 1947. The regular season ended on September 28, with the Brooklyn Dodgers and New York Yankees as the regular season champions of the National League and American League, respectively. The postseason began with Game 1 of the 44th World Series on September 30 and ended with Game 7 on October 6. The Yankees defeated the Dodgers, four games to three, capturing the 11th championship in franchise history. The 14th Major League Baseball All-Star Game was played on July 8, hosted by the Chicago Cubs at Wrigley Field in Chicago, Illinois, with the American League winning, 2–1. The 1947 season is most notable as the year that the baseball color line broke, thanks to the Brooklyn Dodgers starting Jackie Robinson on Opening Day.

Integration: Breaking the color line

On April 15, Opening Day for the National League's Brooklyn Dodgers, Jackie Robinson was in the Dodgers' lineup, playing first base against the Boston Braves at Ebbets Field. His appearance in a major league game broke the baseball color line, the practice of excluding players of black African descent. Though he endured epithets and death threats, as well as a slow start, his skill would earn him the first ever Rookie of the Year award, named in Robinson's honor 40 years later. Halfway through the season on July 5, the American League's Cleveland Indians debuted Larry Doby, becoming the first black player in the American League and breaking the AL color line. Doby was a more low-key figure, suffered many of the same indignities that Robinson did, albeit with less press coverage. Kansas City Monarchs star Willard Brown and teammate Hank Thompson briefly played for the St. Louis Browns, becoming the third and fourth Black players in either the NL or AL, and made the St. Louis Browns the first of either the NL or AL to field two Black players on one roster. Brown was the first black player to hit a home run in the American League.

Schedule

The 1947 schedule consisted of 154 games for all teams in the American League and National League, each of which had eight teams. Each team was scheduled to play 22 games against the other seven teams of their respective league.
