The Seattle Mariners 2002 season was their 26th since the franchise creation. After their record 116 wins the previous year without a World Series appearance, they attempted for a third straight postseason appearance. They ended the season .570, but finished third in the American League West and missed the postseason. This season began a playoff drought that lasted for 20 seasons until 2022, at which point it was the longest in all of the four North American professional sports.
