Both American League expansion teams were put in the AL West, so the AL East started as the stronger division. The rapid rise of the Royals followed by the Brewers; move to the East kept the divisions fairly equal for a few years. An imbalance appeared in the late 70s when the Yankees and Brewers joined the Orioles and Red Sox as strong teams in the AL East. When the Brewers, Orioles, and Yankees faded in the late 80s, and LaRussa&#8217;s A&#8217;s rose, the AL West moved on top for a few years. The split into three smaller divisions made wider swings plausible. The largest came as the Mariners and A&#8217;s put together some outstanding seasons, with the Mariner winning 116 in 2001 and the A&#8217;s putting together consecutive 100+ win seasons. They were joined by the 99 win Angels in 2002.<\/p>\n<p>&nbsp;<\/p>\n<p>YEAR ALEast ALWest ALCent\u00a0\u00a0 NLEast NLWest NLCent\u00a0 Notes<\/p>\n<p>1969\u00a0\u00a0 .530
