The following are the events that happened world-wide throughout the sport of baseball.
- 1888 - Albert Spalding announces a baseball tour to Australia next winter with his Chicago team and a squad of National League All-Stars.
- 1889 - A New York sporting goods house receives an order for bats, balls, and other baseball equipment from Mr. Hiroka of Tokyo, Japan. In his letter he says that baseball "has been played there for several months" and that a baseball association would soon be organized.
- 1915 - The Boston Braves break ground on Commonwealth Avenue and begin construction of Braves Field. Owner Gaffney wants a large enough park so that inside-the-park homers can be hit in three directions. The field will open on August 18.
- 1918 - Although the major leagues optimistically keep the schedules at 154 games, the owners agree to halve the spring training time in an attempt to save money, as the St. Louis Cardinals open their camp at Hot Wells, Arkansas.
- 1925 - In a reprise of the 1924 World Series, the New York Giants edge the Washington Senators 2–1, at West Palm Beach's new Municipal Athletic Field.
- 1934 - Mildred Didrickson (Babe Zaharias), renowned all-around female athlete, pitches the first inning for the Philadelphia Athletics in a spring training exhibition game against the Brooklyn Dodgers. She gives up one walk but no hits. Two days later she pitches again, this time one inning for the St. Louis Cardinals against the Boston Red Sox. Didrickson is less successful this time, giving up four hits and three runs. Bill Hallahan relieves her, as she does not have an at bat in either game. She will also play several games for the House of David this season. Didrickson is the second female to play exhibitions with a major league team. Previously, first baseman Lizzie Murphy played for an American League All-Star team on August 14, 1922.
- At Fort Myers, the Philadelphia Athletics defeat the House of David 4–3.
- At St. Petersburg, the St. Louis Cardinals set a spring training record, drawing 6,467 in a match against the Boston Braves. The big draw is Babe Ruth, who hits a towering fly against Dizzy Dean, then, after Dean departs, laces two doubles into the overflowing crowd. The Cardinals win 5–4.
- 1937 - The Homestead Grays of the Negro Leagues acquire future Hall of Famers Josh Gibson and Judy Johnson for $2,500 in cash and a pair of journeymen players. The trade is considered the largest transaction in the history of the Negro Leagues.
- 1943 - Bob Johnson, a longtime Philadelphia Athletics fan favorite, is traded to the Washington Senators in exchange for outfielder Bobby Estalella and infielder Jimmy Pofahl. Johnson has led the Athletics in RBI in each of the last seven seasons – no team has ever traded a slugger with that mark.
- 1953 - U.S. Senator Edwin C. Johnson offers a bill to give clubs the sole right to ban radio-TV broadcasts of major league games in their own territory. The antitrust division of the Justice Department outlawed this practice in 1949. Johnson believes that it started the decline of baseball in small towns and cities throughout the country. His bill will restore the equity between large communities and the small areas.
- 1954 - The Chicago Cubs send shortstop Roy Smalley to the Milwaukee Braves for pitcher Dave Cole, opening up the shortstop job for Ernie Banks.

- Roberto Clemente becomes the first Hispanic American to gain election to the Baseball Hall of Fame. The Baseball Writers Association of America announces the results of a special ballot, with Clemente receiving 393 of 424 votes. Clemente died in a plane crash on New Year's Eve. In light of his tragic death, the Hall's Board of Directors had waived the five-year waiting period that is normally required before a player is eligible for election. A 12-time All-Star, Clemente batted .317 and won a dozen Gold Gloves over an 18-year career, and batted .362 in World Series play. Named National League MVP in 1966, he was voted the outstanding player in the 1971 World Series, when the Pittsburgh Pirates beat the heavily-favored Baltimore Orioles in seven games.
- In an exhibition game played in Puerto Rico, Willie Mays substitute New York Mets manager Yogi Berra and led his team to a 8–3 victory over the Pittsburgh Pirates.
- 1976 - Leo Durocher, hired to manage the Yokohama Taiyo Whales of the Japanese Central League, is sick with hepatitis and asks for a five-week delay in reporting.

- 1984 - Hall of Fame pitcher Stan Coveleski dies in South Bend, Indiana, at the age of 94. Coveleski pitched for the Philadelphia Athletics, Cleveland Indians, Washington Senators and New York Yankees over a 14-season career, winning 215 games, which include five 20-win seasons.

- Scoring four runs in the first inning with only one ball hit out of the infield and four more in the ninth without an extra-base hit, Japan defeats Cuba 10–6, to win the first World Baseball Classic. A sellout crowd of 42,696 packed PETCO Park for the finale to the 21⁄2-week tournament that fulfilled expectations of its organizers.
