when was the last time all mlb teams opened on the same day
Opening Day Major League Baseball had most of its teams open the 2011 season on a Thursday (March 31) or Friday (April 1) rather than the traditional Monday, in order to prevent the World Series from extending into November.[23] Similarly, most teams opened the 2012 season on Thursday (April 5) or Friday (April 6). However, subsequent seasons through 2017 returned to Monday openers for most teams. For the 2018 season, all 30 teams were scheduled to open the season on Thursday, March 29 (the earliest domestic start for a regular season in MLB history, and the first time since 1968 that all major league teams were scheduled to start the season on the same day, although two games were subsequently rained out and postponed to Friday, March 30).[24]
Designated hitter However, momentum to implement the DH did not pick up until the pitching dominance of the late 1960s. In 1968, Denny McLain won 31 games and Bob Gibson had a 1.12 ERA, while Carl Yastrzemski led the American League in hitting with only a .301 average. After the season, the rules were changed to lower the mound from 15 to 10Â inches and change the upper limit of the strike zone from the top of a batter's shoulders to his armpits. In addition, in 1969 spring training, both the American League and National League agreed to try the designated pinch hitter (DPH), but they did not agree on the implementation. Most NL teams chose not to participate. On March 6, 1969, two games utilized the new DPH rule for the very first time. Two newly formed expansion teams, the Montreal Expos and the Kansas City Royals, would participate in one such game, and the New York Yankees and Washington Senators in the other. On March 26, 1969, Major League Baseball nixed the idea for the time being. However, a four-year trial in which the International League and four other minor leagues started using the DH for their games began that year.[11]
