Seattle Mariners Chairman and Managing Partner John Stanton has written an open letter to the team’s fans following the 2025 season.

The letter, which initially ran as a full-page ad Sunday in The Seattle Times, was posted on the team’s social media channels Monday afternoon along with the caption, “Thank you for being the best fans in baseball.”

The Mariners finished the regular season with a 90-52 record to win their first AL West division championship in 24 years. In the playoffs, they earned a bye past the wild card round with the No. 2 seed in the American League, defeated the Detroit Tigers in five games in an AL Division Series, and went to seven games in the AL Championship Series against the Toronto Blue Jays.

It was the first time the Mariners had ever won three games in the ALCS to come within one win of the World Series, but Toronto won both Game 6 and Game 7 in Canada to deny the M’s their first trip to the Fall Classic.

In Stanton’s letter, he wrote “I’m heartbroken at the way the season ended” and thanked the fans “on behalf of everyone” in the Mariners organization. He also wrote about the team’s commitment to getting to its first World Series.

“The Northwest deserves a World Series. I know we are going to get there. This is the beginning of a special era of Mariners Baseball. There is work to do to take that final step. That work starts now.”

Here is Stanton’s full open letter.

Dear Mariners fans,

There’s no sugar coating it. I’m heartbroken at the way the season ended. We’ve never come closer to bringing our first World Series to Seattle. I know how much our players, coaching staff and front office wanted this for you.

On behalf of everyone in our organization, thank you for the passionate support, energy, rally shoes, mustaches, magic spells and joy you brought to the ballpark all season long.

From Opening Day to the last out of the ALCS, you cheered so loud that you created measurable seismic activity. You stayed on your feet for 15 innings. You showed up with signs, you brought out our players for curtain calls and you started dance parties on the sidewalks after games.

And when the team arrived home at 3 a.m. after the toughest return flight of their careers, you were there to greet us at the airport and the ballpark with “thank you” signs. They saw all of it. They felt all of it. We all did. We played for you, and you pushed our team to heights we have never reached before.

The Northwest deserves a World Series. I know we are going to get there. This is the beginning of a special era of Mariners Baseball. There is work to do to take that final step. That work starts now.

We can’t wait to get back to T-Mobile Park with all of you. Thank you again for being the best fans in baseball.

Go Mariners!
