T-Mobile Park Pregame Guide
Seattle Mariners · Seattle, WA
T-Mobile Park keeps its tailgating in named, bookable spaces rather than in the general parking. The Parking Plaza and Hot Corner sit on Occidental Avenue just outside the ballpark, next to the Mariners Garage, and the club markets them for tailgates, food trucks and tented events. The everyday pregame is The Boxyard across the street — Victory Hall, the Hatback Bar & Grille and Steelheads Alley, with food, drinks, live music and tailgating games. The Mariners Garage opens three hours before first pitch; the T-Mobile 'Pen and the Center Field Gate open two hours before, and every other gate 90 minutes.
Tips & Fan Reports
Aim for the T-Mobile 'Pen or the Center Field Gate if you want in early — they open a half hour before everything else.
The Boxyard across the street is the default pregame, and it has tailgating games without needing a lot.
A group tailgate here means booking the Parking Plaza or Hot Corner on Occidental Avenue rather than using a parking bay.
The Mariners Garage opens three hours out, an hour before the earliest gate.
