PHOENIX -- Fans will be back in the stands at Chase Field in 2021, which is expected to open at 25 percent capacity, and the team has instituted some procedural changes to help ensure the health and safety of everyone who comes through the gates.

The main difference will be that everything from concession stands to the team shop will be cashless and as contactless as possible.

"We want our fans to feel very comfortable, very confident, especially on their first visit, where they see that these protocols are in place," D-backs team president/CEO Derrick Hall said.

The gates to the ballpark will open 30 minutes later than usual, and only clear bags will be allowed in, which will reduce the contact with those who check the bags. A clear bag with a D-backs logo on it will be the first giveaway during the home-opening series with the Reds. The first 5,000 fans for each of those games will receive a bag.

Only electronic tickets will be used, which will eliminate another touch point.

Once inside the ballpark, fans can order food remotely using the team's ballpark app, which will send an alert when the food is ready, which should reduce the amount of time spent waiting in line.

Masks will be required except for when fans are actively eating or drinking. Much like they do during Spring Training games at Salt River Fields, the team's gameday staff will walk through the aisles holding signs to remind fans to wear their masks.

"We will have obviously a mask mandate here in the ballpark," Hall said. "We're enforcing masks. We're making sure that the masks are not gaiters, that they're not handkerchiefs or face shields. If you're going to use a face shield, we're making sure you have the proper mask underneath that."

Initially, Chase Field's capacity is expected to start around 12,000, though the team will explore allowing more fans in depending on how the COVID-19 infection rates in Arizona are going and what directives they receive from state and local governments.

Arizona Gov. Doug Ducey on Thursday lifted some of the state's COVID-19 restrictions, which could impact whether the team decides to allow in more fans. Hall said the team would exercise caution in expanding seating capacity.

"I can't see us going from zero to 100 right away," Hall said.

To ensure that people remain socially distanced during games, the team has zip tied seats to prevent overcrowding in sections, and tickets are sold in pods of between one and five people.

Like every year, there will be a number of new food items on the menu as well. Some of them include:

• Poblano Cheesesteak (shaved Philly ribeye, American cheese, fire roasted poblano chile, barbecue aioli, battered onion straws)

• Beer Cheese Bratwurst (beer bratwurst, pub beer cheese, griddled onion, brown mustard, pretzel roll)

• 505 Green Chile, Chicken Bacon and Ranch Tots (grilled chicken, tots, nacho cheese, bacon, 505 green chile)

• Ultimate Bacon Pub Burger (chuck patty, pub beer cheese, bacon, battered onion, barbecue sauce, pickles, potato roll)

• Danzeisen Dairy Chocolate Mint Chip Stack Shake

Gadzooks Enchiladas and Soup will have two locations at the ballpark this year, and there will now be Fry's Grab n' Go stands throughout the main concourse stocked with small bites, drinks and pre-packaged goods.

For those 21 and over, The Still at Cutwater, featuring award-winning distillery Cutwater Spirits, will have an assortment of ready-to-enjoy canned cocktails, including limited-edition cans of its popular classic Vodka Mule with D-backs marks.

The team has also overhauled its D-backs Kids Club, which rewards fans 15 and younger for attending games. In keeping with the contactless protocols, the membership cards will be digital and kids will be rewarded with different items ranging from a Nick Ahmed poster to a wrist watch depending on how many games they attend.

"The team is really looking forward to Opening Day now with fans starting to come back into the ballpark," said former D-backs star Luis Gonzalez, who works in the team's front office. "Fans are part of the game, and to have them in the ballpark really energizes [the team] and gets them going in the right direction."
