2008 Seattle Mariners season

The 2008 Seattle Mariners season was the 32nd Major League Baseball season in the team's history. Coming off the heels of the previous 2007 season, in which the Mariners finished with their first winning record since 2003, the team was widely expected to once again compete for the American League West championship. The team was bolstered by some major roster additions during the previous offseason, most notably starting pitchers Érik Bédard and Carlos Silva. However, by the end of May, it became apparent that the team had gone back to its losing ways of the 2004–06 seasons. Despite their losing ways, they won their first and last game of the season. Their longest winning-streak of the season is 4 games after a sweep of the Cleveland Indians at the end of August and a 12-6 win against the Texas Rangers on the first day of September. However, standing at 57–87, their longest losing-streak of the season is 12 games, 11 on the road, 1 at home, after being swept by the Los Angeles Angels of Anaheim, Kansas City Royals, Oakland Athletics, and suffering a loss at the last homestand opener against the Angels. On September 23, the Mariners became the first club to spend $100 million in payroll and lose 100 games. The team finished the season with a .370 record, last in the West for the 4th time in 5 years, and second worst in the majors.

With the team underperforming and underachieving, a number of people who had become scapegoats for the team's underperformance were dismissed during the season, most notably general manager Bill Bavasi, field manager John McLaren, first baseman Richie Sexson, and designated hitter José Vidro.
