The quick read

T-Mobile Park opened in 1999 as Safeco Field, built to keep the Mariners in Seattle after a stadium fight that came down to the wire, and it carried the nickname “the house that Griffey built.” The roof made baseball work in a rainy city. The name changed to T-Mobile Park in 2019, but the history that draws fans here is older than the building: Ken Griffey Jr., Edgar Martinez’s 1995 “Double,” the 116-win 2001 team, Felix Hernandez’s perfect game, the 2022 club that finally ended a 21-year wait for October baseball, and the 2025 team that got within a game of the World Series.

One thing to get straight first. Edgar Martinez’s 1995 Double, the moment widely credited with saving baseball in Seattle, happened at the Kingdome, the Mariners’ home from 1977 through the middle of 1999. It did not happen in this building. It is the reason this building got built.

What it replaced

The Mariners spent their first 22-plus seasons in the Kingdome, the concrete domed stadium next door. By the mid-1990s it was failing, and the team was openly threatening to leave Seattle. King County voters rejected a stadium tax on September 19, 1995. Three and a half weeks after that, the governor called the legislature into special session, and on October 14 it authorized a different package. The new ballpark went up just south of the Kingdome, and ground broke in 1997 with Ken Griffey Jr. at the ceremony.

The park opened on July 15, 1999, right after the All-Star break. The Mariners lost the first game 3-2 to the San Diego Padres in front of 44,607, with broadcaster Dave Niehaus throwing the ceremonial first pitch. The Kingdome was demolished in 2000.

The house that Griffey built

Ken Griffey Jr. was the player the whole stadium fight revolved around, and when the new park opened the franchise leaned into the connection. After Griffey returned to Seattle as a visiting player in 2007, the team unveiled a poster calling the park “the house that Griffey built,” and the phrase stuck.

Here is the part the nickname leaves out. Griffey played half a season in the new building, asked out, and was traded to Cincinnati in February 2000, before its first full year. The house he forced into existence is one he barely played in, and the poster arrived eight years after he stopped playing in it. He came back to Seattle in 2009 and retired the following year.

The park opened as one of the more pitcher-friendly in baseball, so the Mariners moved the fences in before the 2013 season to even things out for hitters, and put in a scoreboard of more than 11,000 square feet. That board was itself replaced for the 2026 season, a new center-field display about 200 feet across.

Edgar’s Double (1995)

Ask a Mariners fan for the moment that mattered most and you will get The Double, and it happened at the Kingdome rather than here. It is the reason this park exists at all. In Game 5 of the 1995 American League Division Series against the Yankees, with the Mariners down a run in the 11th, Edgar Martinez lined a two-run double down the left-field line to win it, scoring Joey Cora and Ken Griffey Jr. Mariners fans just call it “The Double.” That series, and the postseason energy around it, is widely credited with saving baseball in Seattle and getting this ballpark built.

The 116-win team

The 2001 Mariners won 116 games, tied with the 1906 Cubs for the most in a single season in major-league history. The team was led by Ichiro Suzuki, who arrived from Japan that year and won both the AL MVP and Rookie of the Year. The run ended in the ALCS against the Yankees, but the 2001 club remains one of the best regular-season teams the sport has ever fielded.

Felix and the perfect game

Felix Hernandez, “King Felix,” gave the park its signature individual performance: on August 15, 2012, he threw a perfect game against the Tampa Bay Rays, winning 1-0 with 12 strikeouts. It was the first perfect game in franchise history and the 23rd in major-league history. His starts drew the King’s Court, a section of fans in yellow shirts waving yellow K cards with every strikeout, and the tradition became part of the park’s identity.

The drought and what came after

After the 2001 team, the Mariners went 21 years without another postseason appearance, the longest active drought in major North American pro sports by the time it ended. It broke in 2022, when Cal Raleigh’s walk-off pinch-hit home run clinched a spot. The Mariners then beat Toronto in the Wild Card round before losing the Division Series to the Astros.

They have been back since, and 2025 is the season that now sits closest to the top. Seattle won the AL West and took Toronto to a seventh game in the ALCS, leading 3-1 in the seventh inning before George Springer’s three-run home run turned it into a 4-3 Blue Jays win. Toronto went to the World Series. Seattle remains the only franchise in baseball that has never played in one, and 2025 is the nearest it has come in fifty seasons.

Statues and retired numbers

Three statues stand outside on the plaza: Ken Griffey Jr. (2017), at the corner of Edgar Martinez Drive and Dave Niehaus Way by the Home Plate Gate, Edgar Martinez (2021), on the south side along Edgar Martinez Drive, and Ichiro (April 10, 2026). A fourth, of broadcaster Dave Niehaus (2011), is inside the park on the main concourse near Section 105, so that one takes a ticket. All four are by sculptor Lou Cella.

The Ichiro unveiling did not go to plan. As Griffey and Martinez pulled the drapery off, the bronze bat the statue holds aloft snapped at the handle and hung there at an angle. Ichiro laughed, and the Mariners had the bat reconnected quickly.

The retired numbers are 24 (Griffey, retired 2016), 11 (Edgar, retired 2017), and 51, which the team has now retired for both Ichiro (August 2025) and Randy Johnson (May 2, 2026), with the two jerseys hanging side by side. Ichiro wrote Johnson in 2001 asking to wear the number, Johnson gave his blessing, and Johnson later pushed his own number-retirement ceremony back a year so Ichiro could have 2025 to himself. Randy Johnson also threw the franchise’s first no-hitter. The number 42 is retired across baseball for Jackie Robinson.

The park has also hosted the wider sports world: the 2001 MLB All-Star Game (July 10, 2001, a 4-1 American League win, and Cal Ripken Jr.’s final All-Star Game, which he capped with a home run and the MVP award), the 2023 All-Star Game, WrestleMania XIX in 2003 (the venue’s record crowd of 54,097), and the 2024 NHL Winter Classic.

A fifth statue arrives on September 3, 2026: Mike Cameron and Mark McLemore with the American flag McLemore carried around the bases the night the Mariners clinched the AL West, eight days after the September 11 attacks. It goes in the Center Field Plaza, and the unveiling falls in the 25th anniversary year.
