Even though the Mariners will be on the road, T-Mobile Park will be opening their gates for the inaugural Batter Up Brewfest! Enjoy tastings from local breweries (like Gtown!) and Mariners Partners, cast your vote to crown “Fan Favorite" and “Best Name” and watch the game against the Rays on the big screen starting at 1:10 p.m. Doors open at 11:30 a.m. and the fest runs thru the length of the game.
