Game Day Timeline
What the day looks like at T-Mobile Park, hour by hour.
Explore Pioneer Square
Head to Seattle's oldest neighborhood for pregame drinks at Sluggers or Pyramid Alehouse. The cobblestone streets and brick buildings set a great atmosphere.
Walk through SoDo
The walk south from Pioneer Square takes you past food trucks and the growing SoDo brewery scene. Georgetown Brewing is worth a stop.
Enter and grab garlic fries
The garlic fries are a T-Mobile Park institution. Get them early before the lines build. Head to the main concourse behind home plate.
Watch batting practice
Head to the left-field stands for BP. The retractable roof will be open or closed. Check the Mariners app for the call.
Find your seat and enjoy the view
On clear days, the view from the upper deck includes the downtown skyline, Puget Sound, and Mount Rainier. Even the roof-closed view is impressive.
Play ball
Nine innings of Mariners baseball. The roof keeps the rain out and the atmosphere in. The Pen gets loud when the team rallies.
Stretch and sing
The crowd sings 'Take Me Out to the Ball Game.' Grab a final round of Ivar's or a craft beer before the late innings.
Head to Pioneer Square or SoDo
Walk north to Pioneer Square bars or south to the SoDo breweries. The Link Light Rail runs late. Take it from Stadium station.
Tips & Fan Reports
Take the Link Light Rail, Stadium station is directly behind center field. Two minutes to the gates.
Link Light Rail to Stadium station is the easiest way in. Connects directly from SeaTac Airport.
Garlic fries are the iconic T-Mobile Park food. Get them in the first inning or during BP to avoid peak lines.
The retractable roof stays closed for rain (frequent) but opens on dry days, Seattle summers are gorgeous when the sun comes out.
The view of the Seattle skyline and Puget Sound from the upper deck is one of the best in baseball.
Pioneer Square (5 min walk) has Seattle's best pregame bars. Pyramid Alehouse and Slugger's are fan favorites.
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.
Aim for the T-Mobile 'Pen or the Center Field Gate if you want in early. They open a half hour before everything else.
Before the Game
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.
