The following are the events that happened world-wide throughout the sport of baseball.
- 1888 - In Detroit, Michigan is organized a club to compete in the International Association next season to take the place of the disbanded Detroit Wolverines, fifth place finishers this past season in the National League. The Wolverines sell of their stars, including Big Sam Thompson going to the Philadelphia Phillies, and the so-called "Big Four" Dan Brouthers to the Boston Beaneaters, Hardy Richardson to the Boston Reds and Jack Rowe and Deacon White to the Pittsburgh Alleghenys.
- 1919 - Clark Griffith becomes a club owner and president when he joins Philadelphia grain broker William Richardson in buying controlling interest in the Washington Senators for $175,000. Griffith, unable to get financial help from the American League, mortgages his Montana ranch to raise funds.
- 1930 - Veteran pitcher Hippo Vaughn is reinstated by Judge Landis after eight years of ineligibility. Vaughn, who had lost a double no-hitter duel to Fred Toney in the 1917 season, had jumped the Chicago Cubs in 1922. Vaughn chose to pitch for a semipro team following a salary dispute with Chicago. He will go to spring training with the Cubs in 1931 but will fail to make the team at age 43.
- 1932 - Donie Bush, pennant-winning manager of the American Association Minneapolis Millers, is named to manage the Cincinnati Reds.
- 1948 - In a move that will give their pitching ace for the next deacade, the Chicago White Sox acquire young left handed Billy Pierce from the Detroit Tigers for All-Star catcher Aaron Robinson. The Tigers even sweeten the deal with $10,000. Pierce will win 186 games for the White Sox over the next 13 years. Robinson will last fewer than three seasons in Detroit.
- 1950 - After nine years at the helm, the Cleveland Indians fire their manager, Lou Boudreau, amid the howls of fan protest. Although Boudreau's overall winning percentage is a moderate .529, he won 92 games in a fourth-place finish – his best showing since 97 victories in the 1948 World Championship season. Al Lopez, who has piloted Minneapolis (American Association) since 1948, takes over with a two-year contract.
- 1951 - In Tokyo, 50,000 fans are on hand as an American All-Star team battles a Central League All-Star team. Joe DiMaggio hits a 400 ft. home run in the eighth inning to tie the game at 1–1, then his brother Dom laces an RBI-triple in the ninth and later scores to give the Americans a 3–2 victory. The Americans have won 12 games and tied one.
- 1953 - The New York Giants end their tour of Japan. It is reported that each player received just $331 of the $3,000 they were promised.

- Joe Torre, who hit 24 home runs for the St. Louis Cardinals and led the National League in RBI (137) and batting average (.363), wins the MVP Award over Willie Stargell of the Pittsburgh Pirates (48, 125, .295). Torre receives 318 points to Stargell's 222.

- 1978 - In a major trade, the New York Yankees send former Cy Young Award winner Sparky Lyle along with four players to the Texas Rangers. In return, Texas pack up pitcher Dave Righetti and four players to the Yankees. Righetti, considered the top left handed prospect in the minors, will win Rookie of the Year honors in 1981.

- 1988 - Los Angeles Dodgers pitcher Orel Hershiser, who posted a 23-8 record with 178 strikeouts and a 2.31 ERA, is a unanimous choice as National League Cy Young Award winner.

- 1996 - At Tokyo, in the finale of the Japanese team against the MLB All-Stars, Japan rally for three runs to earn an 8–8 tie. The Americans hit .302 in the series with 11 home runs, and come away with four wins, two losses, and two ties. None of the games go extra innings. Steve Finley, who hit 8-for-20 with nine RBI, is named MVP.
- Roger Clemens becomes the first American League pitcher to win the Cy Young Award four times. Clemens, the first pitcher since Hal Newhouser in 1945 to win the pitching Triple Crown in the American League, led the league in wins (21), strikeouts (292) and ERA (2.05) in his first season with the Toronto Blue Jays. Clemens won his first three Cy Young Awards with the Boston Red Sox in 1986, 1987 and 1991.
