Labor strife and more moving
1972 was tainted by a players' strike over pension and salary arbitration. The strike erased the first week and a half of the season, and the Leagues decided to just excise the lost portion of the season with no makeups. As a result, an uneven number of games were lost by each team; some as few as six, some as many as nine. The lack of makeups, even when they affected the playoffs, led to the Boston Red Sox losing the American League East by half a game to the Detroit Tigers.
1972 marked the first year for the Texas Rangers, who had moved to Arlington from Washington, D.C. (where they played as the Washington Senators) after the 1971 season. The team was one of the worst ever fielded by the franchise, losing 100 games for the first time since 1964. Manager Ted Williams hated it in the Dallas-Fort Worth area, and resigned at the end of the season. To make room for the Rangers in the American League West Division, one of the teams already in that division would have to switch to the East Division. Technically, both the Chicago White Sox and the Milwaukee Brewers were the easternmost teams in the West Division, but only one of them could move. It was decided that Milwaukee, as the newer franchise, would make the move. The Brewers and White Sox would again become divisional rivals in 1994 with the formation of the American League Central, but this would last only through 1997, when Milwaukee transferred to the National League.
1972 would mark the Kansas City Royals' final year at Kansas City Municipal Stadium, as the next year they would move to Royals Stadium at the Truman Sports Complex in suburban Kansas City.
Most teams (18 of 26) switched from wool flannel uniforms to double knit uniforms made of nylon and rayon at the outset of 1972. The Pirates were first to adopt double knits when they moved from Forbes Field to Three Rivers Stadium in July 1970. The Cardinals switched at the start of the 1971 season, and the Orioles gradually phased out their flannels throughout 1971, becoming all-double knit in time for the postseason.
The Giants wore flannels until midseason, going to double knits at home only; the flannels would not be phased out for the road uniforms for 1973. The Red Sox switched to double knits midway through 1972. Only the Royals, Expos and Yankees wore flannels full-time during the 1972 season, and all three converted to double knits for 1973.
The World Series was won by the Oakland Athletics, the first of three straight behind the bats of Reggie Jackson and Bert Campaneris, and the pitching cadre of Catfish Hunter, Rollie Fingers, and Vida Blue. The year ended on a sad note when Roberto Clemente died in an airplane crash off the coast of San Juan, Puerto Rico, on New Year's Eve, while participating in aid efforts after the 1972 Nicaragua earthquake.
