2022 Seattle Mariners season

The 2022 Seattle Mariners season was the 46th season in franchise history. The Mariners played their 23rd full season (24th overall) at T-Mobile Park, their home ballpark in Seattle, Washington. The Mariners finished the regular season at 90–72, equaling their record from 2021, and successfully reached the postseason for the first time since 2001.

On December 2, 2021, The Commissioner of Baseball, Rob Manfred announced a lockout of players. This occurred following expiration of the collective bargaining agreement (CBA) between Major League Baseball (MLB) and the Major League Baseball Players Association (MLBPA). On March 10, 2022, MLB and the MLBPA agreed to a new collective bargaining agreement, thus ending the lockout. Opening Day took place on April 8, 2022. MLB previously announced several series would be cancelled due to the lockout, but the agreement provided a 162-game season, with originally canceled games to be made up via doubleheaders.

On July 17, the Mariners became the first team to enter the All-Star break with a 14-game winning streak, their second longest in club history. For the 21st season in a row, the Mariners failed to win the AL West.

On September 30, Cal Raleigh hit a walk-off home run against the Oakland Athletics, clinching their first playoff berth since 2001. It ended the longest major professional sports postseason drought in North America. They defeated the Toronto Blue Jays in the ALWCS, but lost to the eventual champion Houston Astros in the ALDS. The Houston series involved a three-game sweep against the Mariners, complete with an 18-inning loss where they failed to score a single run in their first postseason game played in Seattle since October 18, 2001. The longest postseason drought in major North American sports now belonged to the Sacramento Kings of the National Basketball Association, who had failed to make the playoffs every year since 2006. However, the Kings clinched a playoff berth the following April, and as a result, the Buffalo Sabres of the National Hockey League and the New York Jets of the National Football League now share the longest drought, each missing the playoffs each of the last 12 years. MLB’s longest playoff drought is now shared by the Los Angeles Angels and the Detroit Tigers at 9 years after the Philadelphia Phillies ended the second longest playoff drought in MLB and the longest in the NL.

Lockout
The expiration of the league's collective bargaining agreement (CBA) with the Major League Baseball Players Association occurred on December 1, 2021 with no new agreement in place. As a result, the team owners voted unanimously to lockout the players stopping all free agency and trades.

The parties came to an agreement on a new CBA on March 10, 2022.

Rule changes
Pursuant to the new CBA, several new rules were instituted for the 2022 season. The National League will adopt the designated hitter full-time, a draft lottery will be implemented, the postseason will expand from ten teams to twelve, and advertising patches will appear on player uniforms and helmets for the first time.
