<P> The Mariners played their first game on April 6 , 1977 , to a sold - out crowd of 57,762 at the Kingdome , losing 7 -- 0 to the California Angels . The first home run in team history was hit on April 10 , 1977 , by designated hitter Juan Bernhardt . That year , star pitcher Diego Seguí , in his last major league season , became the only player to play for both the Pilots and the Mariners . The Mariners finished with a 64 -- 98 record , echoing the record the 1969 Pilots once held . In 1979 , Seattle hosted the 50th Major League Baseball All - Star Game . After the 1981 season , the Mariners were sold to California businessman George Argyros , who in turn sold the team to Jeff Smulyan in 1989 , and then to Nintendo of America in 1992 . </P>
