The KeyBank Diamond Club offers the best seats in the ballpark as well as an amazing and truly unique ballpark experience. There are 370 KeyBank Diamond Club seats in this exclusive area located in the first eight rows behind home plate. From the KeyBank Diamond Club seats you'll see the break of a slider, hear the pop of the mitt, perhaps even chat with the on-deck hitter and help the umpire call balls and strikes.
A private, field level entryway takes you into the KeyBank Diamond Club Lounge and the exclusive seating area. The KeyBank Diamond Club Lounge is a spacious, upscale bistro with a circular bar, big screen TV's and luxurious tables, chairs and sofas.
Your membership in the KeyBank Diamond Club includes all food and beverages served in the private KeyBank Diamond Club Lounge or at your seat by our attentive staff. Executive Chef Jim Makinson plans a delicious buffet menu for each game, which you can enjoy in the Lounge or take out to your seats. Standard ballpark fare items are available as well and will be delivered to your seats so you never have to miss any game action.
Whether entertaining clients, family members or friends, you are sure to impress your guests with the exceptional amenities of the KeyBank Diamond Club at Safeco Field.
