2001 Seattle Mariners season

From a winning percentage record, it would only be surpassed in modern baseball by the 2020 Los Angeles Dodgers, who finished 43-17 (.71667) in a pandemic-shortened season.

The 2001 Mariners hold the record for the most Wins Above Replacement (WAR) by a team in a season in MLB history, with 50.4.

They became the first team in MLB history to win 110 or more regular season games and fail to reach the World Series.

Despite the record-setting win total, the Mariners would not reach the postseason again until 2022, which was the longest active drought in the four major North American sports.

The Mariners hosted the 2001 Major League Baseball All-Star Game on July 10, 2001 at Safeco Field.
