The fact is however… the Kingdome was never meant for the Mariners. It was actually intended for the Seattle Pilots and the Kingdome was yet one more joyless failure of Major League Baseball's shortest lasting expansion team. Fans of professional baseball had it good here when this was a Triple-A Pacific Coast League town, playing at beautiful Sicks Stadium (when it was a simple Triple-A ballpark). When the Major Leagues however tried to make Seattle a full time home, everything went awry… and we do mean everything.
