SEATTLE -- T-Mobile Park has only been open since 1999, but it has already been home to some of the most memorable moments in Major League history. Nestled one block south of where the Kingdome once stood, which itself housed some of Seattle’s most iconic memories, the open-air, retractable-roof replacement has blossomed into one of the favorite West Coast stops on the big league circuit.
Here are the Mariners' best moments in the ballpark’s history.
1) The 116th win: Oct. 6, 2001, vs. Rangers
The number 116 is synonymous with Seattle, and that history was solidified on the penultimate day of the 2001 season, the most memorable year in Mariners history.
That day, Bret Boone hit his 37th homer in the first inning, which proved to be the difference, as the Mariners defeated the Rangers, 1-0, and handed Texas its first shutout all season. Making it even sweeter was Kazuhiro Sasaki ending the game with a strikeout of an upset Alex Rodriguez, who months prior had jettisoned the Mariners for his historic contract. Legendary Seattle broadcaster Dave Niehaus nearly blew a gasket on the call.
The win that day tied the Mariners with the 1906 Cubs for the most in Major League history, and they had already taken the American League record from the ’98 Yankees, who have been widely viewed as one of the greatest teams ever.
2) Ichiro makes hit history: Oct. 1, 2004, vs. Rangers
The pressure had been mounting for weeks, but Ichiro finally broke George Sisler’s single-season hits record of 257 with a grounder he punched into left field during the third inning, his second hit of the night. Even the reserved Ichiro couldn’t hide emotion as fireworks erupted and he was embraced by teammates on the first-base line.
Three generations of Sislers were in attendance to watch the 84-year-old record fall, and they were among the first Ichiro approached to offer his congratulations and appreciation.
As Niehaus said on the call, he and Mariners fans were relieved that Ichiro accomplished the feat in front of a home crowd instead of on the road. Ichiro would finish with 262 hits that season -- a record that may be unbreakable.
3) The King is perfect: Aug. 15, 2012, vs. Rays
On that sun-soaked Seattle afternoon, Félix Hernández was untouchable. The King coronated himself by throwing the Mariners’ first perfect game and just the 23rd in MLB history, when he struck out 12 Rays, including eight of the final 12 batters he faced, then kissed the tattoos of his children on his pitching wrist and hurled his arms into the sky while arching his right leg -- a gesture that has since been monikered “Felixing.”
It was a getaway day, and despite a hearty King’s Court, the stands were roughly half full. But some who were there say that the intimacy played into the experience. Those in attendance enjoyed far more than a Ferris Bueller experience of missing work or school to be at a ballgame -- they witnessed MLB history.
4) Cal crushes 60th as Mariners clinch AL West: Sept. 24, 2025, vs. Rockies
When they talk about this night for years to come, the dialogue will center on the baseball that was demolished into territory that few have ever reached, along with the banner that would soon descend from the rafters just above where it landed. Cal Raleigh was on the precipice of history when crushing his 59th homer in the first inning, then he upped the ante by launching No. 60 in the eighth, with the Mariners comfortably cruising their way to a 9-3 win over the Rockies -- and their first AL West title since 2001. It was the type of game that will be seared into Seattle’s memory, perhaps even long after T-Mobile Park is gone.
5) The 15-inning marathon: Oct. 10, 2025, vs. Tigers
For a starved fanbase that specializes in stress, the Mariners gave their faithful a dynamite dose in a do-or-die Game 5 of the 2025 ALDS. But in the best way possible. Jorge Polanco ripped a walk-off single through the right-side hole with one out and the bases loaded in the bottom of the 15th inning, sending Seattle to just its fourth ALCS ever and first since 2001. The way in which they won carried some extra validation, too, given that the Mariners were on the wrong side of an extremely long playoff game in this very building three years prior, the 18-inning loss to Houston in Game 3 of the ‘22 ALDS that ended their season.
6) Geno’s emotional ALCS slam: Oct. 17, 2025, vs. Blue Jays
With nothing going in their first two home games of a tense series that went the full seven games, Cal Raleigh tied up Game 5 with a solo homer in the eighth inning, then a few moments later, Eugenio Suárez went for the dagger with a punctuating grand slam that sent Seattle into the seismic. At the podium postgame, with his two daughters on his lap, a rarely emotional Suárez teared up while calling it the biggest moment of his career -- one that had storybook level appeal.
7) “The drought is over!”: Sept. 30, 2022, vs. A’s
It wasn’t just that the Mariners finally ended the longest active playoff void in North American professional sports on that epic night, but the way in which they did it. Bottom of the ninth, tie game and their unknowing face of the future at the dish. When Cal Raleigh crushed that solo shot off the windows of the Hit It Here Cafe, an entire region breathed a collective sigh of relief and celebrated in a way it hadn’t in over 20 years.
8) All-Mariner All-Star Game: July 10, 2001
The 2001 Midsummer Classic had just about everything. Set to retire at season’s end, Cal Ripken Jr. and Tony Gwynn capped their illustrious All-Star Game careers with Ripken homering then being honored with Gwynn in a ceremony of recognition that halted the game. Tommy Lasorda took an infamous tumble when Vladimir Guerrero’s broken bat went flying down near Lasorda’s post as third-base coach. Roger Clemens and Mike Piazza faced off for the first time since their bizarre meeting in the World Series.
And at the center of it all were the Mariners. The game was in their home digs. They were represented by four in the starting lineup -- Ichiro, Bret Boone, John Olerud and Edgar Martinez -- and four more on the bench: Mike Cameron, Sasaki, Freddy Garcia and Jeff Nelson. Manager Lou Piniella was on the AL’s coaching staff. Ichiro boldly beat out an infield single off Randy Johnson in the first inning then immediately stole second base. Sasaki picked up the save for the AL’s 4-1 win.
9) Squeeze and shock: Oct. 6, 2000, vs. White Sox
The first postseason game in the new yard was an epic one, as Seattle finished a sweep of Chicago on the heels of an unexpected squeeze play by Carlos Guillen that scored pinch-runner Rickey Henderson for a ninth-inning walk off.
The 48,010 on hand -- the largest crowd in the park’s history to that point -- erupted from shock to shout as Guillen’s ball dribbled past pitcher Keith Foulke, first baseman Frank Thomas and second baseman Ray Durham into right field. Guillen’s intent, at Piniella’s urging, was to hit in Thomas’ direction, given that the Big Hurt wasn’t playing the field regularly. That sparked some improvisation to bunt, even with the White Sox playing in to account for Henderson's speed.
The Mariners continued their pace as the hottest team in the league at the time, having clinched the playoffs on the final day of the season.
