This media guide was distributed in 1978 at the Kingdome for the Seattle Mariners. They finished this season with a record of 56-104. The Seattle Mariners are an American professional baseball team based in Seattle, Washington. Enfranchised in 1977, the Mariners are a member of the Western Division of Major League Baseball’s American League. Before being awarded a team in Major League Baseball, Seattle had been a staple of the Pacific Coast League dating back to the late 19th century. The first attempt to land a major league team failed when a bid by William Daley to move the Cleveland Indians to Seattle in 1965 fell apart. In late 1967, Daley, by then having sold the Indians, led a consortium to win a franchise in the 1969 expansion. That team became the Seattle Pilots. The Seattle Pilots, amidst a bevy of financial problems, were sold and relocated to Milwaukee for the 1970 season and became the Milwaukee Brewers. The first original Mariners logo consisted of a large yellow circle with a subtle dark blue outline, the name “Seattle Mariners,” and a little lower – “Baseball club.” In the word “Mariners,” the letter “M” is replaced by a marine blue trident.
