Seattle Mariners had one brief baseball gambling season of Major League Baseball in 1969 with the expansion Pilots, who fled for Milwaukee after that inaugural baseball bet season. In 1977 baseball gambling season, the American League decided to try again and the Mariners opened up for business at the Kingdome. From 1977-90 the Mariners were a baseball bet franchise without direction, and with plenty of managerial and roster changes. About their only identity was that of a losing team that played in a sterile dome full of empty seats.
All of the losing did serve one positive purpose for Seattle, however, as they stockpiled a lot of quality young talent such as Harold Reynolds, Scott Bankhead, Edgar Martinez, Jay Buhner, Erik Hansen, and superstars to be Randy Johnson and Ken Griffey, Jr. Finally, in 1991 baseball gambling season, Seattle had its first taste of winning baseball as the Mariners finished 83-79. Despite the winning season, manager Jim Lefebvre was fired.
Manager Lou Piniella arrived in 1993 baseball gambling season and by 1995 the Mariners were ready to enter contender status. Seattle baseball bet fans that had been considered fickle and amongst the worst in baseball, began to respond to the 1995 pennant drive despite their early resistance due to resentment from the 1994 strike. Seattle chased down the Angels to force a one game playoff for the AL West title, which Seattle clinched at home in front of a sellout crowd. In the ALDS the Mariners quickly fell 2-0 down in games to the Yankees before returning home to a crowd of over 58,000 as Seattle became a baseball gambling town. Seattle rallied to win three straight and upset the Yankees, making the ALCS against Cleveland. The Mariners lost the series but, in the process, won a new stadium proposal and were on their way! In 1997 baseball gambling season, the M’s drew over 3-million baseball bet fans en route to a Division title before they lost to Baltimore in the ALDS.
In July of 1999 baseball gambling season the Mariners moved into Safeco Field, one of the most beautiful venues in baseball that includes a retractable roof. Griffey would bolt for Cincinnati and cash after the baseball gambling season but Alex Rodriguez picked up the slack in 2000 baseball gambling season and with a strong pitching staff the Mariners earned the wild card slot, beating Chicago in the ALDS before losing to the Yankees in the ALCS. The following baseball gambling season, despite losing A-Rod, Seattle won an eye popping 116 games, but the baseball gambling season finished bittersweet with a meek 5-game ALCS loss to the Yankees, their last playoff appearance to date.
