# 2020 Seattle Mariners season

The 2020 Seattle Mariners season was the 44th season in franchise history. The Mariners played their 21st full season (22nd overall) at T-Mobile Park, their home ballpark. The Mariners entered this season with the longest active playoff drought in the four major North American professional sports leagues, attempting to make their first postseason since 2001. They also entered this season as the only team to not win a league pennant.
On March 12, 2020, MLB announced that because of the ongoing COVID-19 pandemic, the start of the regular season would be delayed by at least two weeks in addition to the remainder of spring training being cancelled. Four days later, it was announced that the start of the season would be pushed back indefinitely due to the recommendation made by the CDC to restrict events of more than 50 people for eight weeks. On June 23, commissioner Rob Manfred unilaterally implemented a 60-game season. Players reported to training camps on July 1 in order to resume spring training and prepare for a July 24 Opening Day. The 2020 Major League Baseball season saw the adoption of many temporary rules, including universal DH, 7-inning scheduled doubleheaders, and extra innings starting with a runner on second. All affiliated minor league seasons were canceled, leaving top prospects and depth players at the team's alternate training site in Tacoma on an expanded roster.
