The 2022 Seattle Mariners season was the 46th season in franchise history. The Mariners played their 23rd full season (24th overall) in Major League Baseball (MLB) 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 as a Wild Card and finishing second in the American League (AL) West.

The season started on April 8 and was adjusted due to the offseason owners' lockout of the players. 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.

On September 30, Cal Raleigh hit a walk-off home run against the Oakland Athletics, clinching the Mariners' 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 AL Wild Card Series but lost to the eventual champion Houston Astros in the AL Division Series. 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 then belonged to the Sacramento Kings of the National Basketball Association, who had failed to make the playoffs since 2006. However, the Kings clinched a playoff berth the following April, and as a result, the New York Jets of the National Football League now have the longest drought, missing the playoffs for the last 15 seasons. MLB’s longest playoff drought is now owned by the Los Angeles Angels at 11 years.

Offseason

Lockout

The expiration of the collective bargaining agreement (CBA) between MLB and the MLB Players Association (MLBPA) occurred on December 1, 2021 with no new agreement in place. On December 2, following a unanimous vote by MLB team owners, baseball commissioner Rob Manfred announced a lockout of players, which stopped all player transactions. On March 10, 2022, MLB and the MLBPA agreed to a new collective bargaining agreement, ending the lockout. Opening Day took place on April 8. MLB previously announced several series would be cancelled due to the lockout, but the agreement provided a 162-game season, with originally canceled games made up via doubleheaders.

Rule changes Pursuant to the new CBA, several new rules were instituted for the 2022 season. The National League adopted the designated hitter full-time, a draft lottery was implemented, the postseason expanded from 10 teams to 12, and advertising patches would appear on player uniforms and helmets for the first time.

Roster changes In November 2021, the Mariners announced their 2022 coaching staff. Bench coach Jared Sandberg and hitting coach Tim Laker did not return to the team. Jarret DeHart was promoted to hitting coach from assistant hitting coach, and Tony Arnerich was named a hitting coach after coaching in the minors for Seattle. The team did not name a bench coach. Kristopher Negrón, who had managed the Triple-A Tacoma Rainiers, became the first base coach. Former first base coach Perry Hill remained the team's infield coach. Andy McKay, who had been the director of player development, was named a major league coach.

Prior to the lockout, the Mariners added reigning AL Cy Young Award winner Robbie Ray on a five-year, $115 million contract on November 30. The team also acquired All-Star infielder Adam Frazier from the San Diego Padres for Ray Kerr and Corey Rosier.

After the lockout, the Mariners acquired third baseman Eugenio Suárez and outfielder Jesse Winker from the Cincinnati Reds for pitchers Justin Dunn and Brandon Williamson, outfielder Jake Fraley, and a player to be named later, weeks later identified as pitcher Connor Phillips. Season standings
