In 1969, Major League Baseball went through another expansion. Four teams were added to MLB, with two being added to the National League and two to the American League. The expansion teams were awarded to Montreal (NL), San Diego (NL), Kansas City (AL), and Seattle (AL). All four of these cities still have MLB teams today, but the Seattle expansion team of 1969 (Seattle Pilots) only lasted one season. The Pilots were relocated to Milwaukee in 1970, and they became the Milwaukee Brewers.
