Events
January
January 20 – The Baseball Writers' Association of America voters elect Ted Williams to the Hall of Fame. Williams receives 282 of a possible 302 votes.
February
February 28 – Seeking an unprecedented three-year $1.05 million to be divided evenly, the Los Angeles Dodgers pitchers Sandy Koufax and Don Drysdale begin a joint holdout.
March
March 5 – In what will prove to be one of the more influential off-the-field events in Major League history, United Steelworkers union official Marvin Miller is elected the Executive Director of the Major League Baseball Players Association (MLBPA). Under Miller's guidance, the players' union will make major gains such as salary increases, improvements in pension benefits, and the advent of free agency and salary arbitration. Miller will occupy his position from 1966 to 1982, as the players' union was transformed into one of the strongest unions in the United States. March 8 – The Special Veterans Committee waives Hall of Fame election rules and inducts Casey Stengel, recently retired manager of the New York Mets. March 17 – Sandy Koufax and Don Drysdale escalate their threat of retirement by signing movie contracts. On March 30, they will end their 32-day holdout, signing for $130,000 and $105,000 respectively.
April
April 3 – USC pitcher Tom Seaver signs with the New York Mets. He had been drafted by the Braves, but they had signed him to a minor league contract while he was still in college. This voided Seaver's remaining eligibility, and voided the contract. The Mets won a special lottery over Cleveland and Philadelphia to win the right to sign him. April 11 – Emmett Ashford takes the field to officiate a 5–2 Washington Senators win over the Cleveland Indians at Washington, to become officially the first African-American umpire in Major League history. April 12 – Over 50,000 fans show up at Atlanta–Fulton County Stadium to watch the Braves first home game in Atlanta. The Braves fall to the Pittsburgh Pirates in 13 innings, 3–2. April 19 – The California Angels play their first regular-season game in their new ballpark, Anaheim Stadium, in front of 31,660 fans. White Sox pitcher Tommy John is the 3-2 winner, Marcelino Lopez takes the loss for the home team. The Angels' Rick Reichardt scores the first run, with a 1-out solo home run in the bottom of the 2nd inning.
