The Safeco Field signage came down from Seattle’s baseball stadium a week ago, and according to a new report, the T-Mobile name will be up in time for the 2019 season.

Forbes reported Thursday that the Bellevue, Wash.-based wireless carrier is the new naming rights partner with the Seattle Mariners. The report is based on anonymous sources who spoke on background. A Mariners spokesperson told GeekWire that there is no agreement yet.

Safeco Insurance and the Mariners announced in June 2017 that their 20-year naming rights agreement would come to an end after the 2018 season.

Forbes reported on a rumored $6 million annual fee by T-Mobile to gain the rights, but again, the Mariners stressed no deal was in place. The city’s Public Facilities District will have to vote on any lease agreement.

T-Mobile did not have any comment on the report when reached by GeekWire.

The end of Safeco Field (by name) set off speculation over the past year about possible companies that could step in to pay the premiere marketing price tag. Prime Park has been a popular guess for those who thought Amazon might like to get in the game.

There’s no word on what stadium-specific name T-Mobile might attach to the ballpark. T-Mobile Field? Uncarrier Park? It’s hard to imagine the Mariners becoming “True to the Magenta.” Feel free to share your favorite names and slogans in the comments.

T-Mobile has certainly shown its willingness to associate itself with Major League Baseball. The company attached charitable donations to home runs with social media hashtag campaigns during the All-Star Game and the MLB Playoffs.

As T-Mobile waits for approval of its acquisition of Sprint, no doubt the company’s outspoken CEO John Legere would like to match what at least one wireless competitor has done in naming rights — AT&T Park in San Francisco is home to the Giants.

Pass on the garlic fries, crickets or Dippin’ Dots, maybe baseball fans should be ready for “Slow Cooker Sundays” at the ballpark.
