Chase Field

The Diamondbacks' retractable-roof ballpark

Chase Field is the 48,330-seat home of the Arizona Diamondbacks, a retractable-roof ballpark at 401 East Jefferson Street in downtown Phoenix. It opened on March 31, 1998, as Bank One Ballpark and took the Chase name in 2005 after Bank One merged with JPMorgan Chase. The building is owned by the Maricopa County Stadium District.

The roof takes about four and a half minutes to open or close. The design lets the Diamondbacks play outdoors in the cooler parts of the season and indoors, air-conditioned, through the Phoenix summer. Since artificial turf replaced grass in 2019, the roof can stay closed for long stretches. When it is open, the sun becomes the main seating question.

• Diamondbacks games: the MLB regular season runs late March or early April to late September, with postseason games in October when the team qualifies.
• Other events: the 2011 MLB All-Star Game, World Series games in 2001 and 2023, and the 2019 WWE Royal Rumble.

Seating chart and layout of the four tiers

The seating layout is a four-tier grandstand that runs from the left-field foul pole around home plate to the right-field foul pole, with bleachers behind both outfield fences. Sections use three-digit numbers, and the first digit names the level.

• 100 level (field level): the lower bowl. Section 122 sits behind home plate, and sections climb from the first-base side toward the third-base side, with section 115 on the first-base line. Infield sections such as 122 run from row 21 at the front to row 39, with additional lettered rows behind.
• 200 level (mezzanine): the middle tier of club and suite seating; the park has about 4,400 club seats and 57 suites overall.
• 300 level (upper deck): the top tier and the least expensive seats in the grandstand, with the Sandlot area on this level.
• Outfield: bleachers in left and right field, and the pool area behind the right-center field fence, about 415 feet from home plate. The pool holds 35 guests and is rented as a suite.

Within a section, lower seat numbers are on your right as you face the field, according to seating guides. Confirm section and row on the listing map before you buy.

Where to sit, with the roof open or closed

With the roof closed, every seat is climate controlled and the choice is purely about view and budget. With the roof open, sun decides most of it.

• Best overall view: 100-level sections around 122, rows 21 to 30. Netting runs in front of roughly sections 115 to 129, so sit beyond those for a clear look at the corners.
• Best for shade with the roof open: the third-base side, which shade guides call the shade side. Upper sections 314 to 318 and 328 to 332 are the safest choices for an afternoon game, and the back rows of 319 to 327 sit under roof cover.
• Best value: the 300 level between the bases, where you see the full field and the roof structure overhead.
• A different experience: the outfield bleachers and the pool area, which suit groups more than scorekeepers.

Seats to think twice about: the first-base side and right field take the most sun on open-roof afternoons in spring and fall. Ballpark guides disagree on which dugout the Diamondbacks use, so if sitting behind the home bench matters, check the dugout label on the listing's seat map.

Getting there: light rail, parking and rideshare

Light rail: Valley Metro Rail's A Line stops at 3rd Street/Jefferson and 3rd Street/Washington, both within a short walk of the ballpark. Trains run every 15 to 20 minutes, every day of the year, connecting Phoenix, Tempe and Mesa. This is the simplest option for anyone staying near a station.

Parking: garages and surface lots ring the downtown block, including the Chase Field garage and the Jefferson Street Garage. Prices and payment rules change by season and by operator, so reserve ahead on weekends and when another downtown arena event overlaps. Check the Diamondbacks' parking page for current details.

Rideshare: drop-offs are easy before the game; after the final out, walking a few blocks away from the ballpark before requesting a car usually shortens the wait.

Bag policy, food rules and gates (as of the 2026 season)

As of the 2026 season, Chase Field allows each guest one of the following:

• a clear plastic, vinyl or PVC bag no larger than 12 by 6 by 12 inches,
• a one-gallon clear plastic freezer bag,
• plus a small clutch no larger than 4.5 by 6.5 inches.

Chase Field is one of the more generous parks on food. Outside food is allowed in a clear plastic bag, along with sealed plastic bottles of non-flavored water, empty plastic bottles and sealed juice boxes. That rule alone can change your plans for a family outing.

Gates open 90 minutes before first pitch Sunday through Friday and two hours before on Saturday. Re-entry is offered through Gates A, F, J and K with a scan out and scan in. For roof status on game day, the team publishes a roof information page and a roof hotline. Check the Diamondbacks ballpark guide for current rules before you go.

Concessions and amenities

Concessions are cashless. Reverse ATMs that turn cash into a payment card sit near sections 106 and 128 on the main concourse and 322 on the upper concourse. Family restrooms are near sections 109 and 135, and Guest Relations is at sections 128 and 322. A new center-field video board, about 9,600 square feet, was added before the 2026 season. Every order through GoodSeats includes free shipping.

History of Bank One Ballpark and Chase Field

Ground was broken on November 16, 1995, and the ballpark opened with the expansion Diamondbacks in 1998. It was the first stadium in the United States built with a retractable roof over a natural grass field. In 2001 the Diamondbacks won all four World Series home games here on the way to beating the New York Yankees in seven. The park hosted the 2011 All-Star Game and returned to the World Series in 2023.

The grass gave way to artificial turf in 2019. In September 2025, Arizona House Bill 2704 was signed into law, allowing sales tax dollars to fund renovations of the stadium.
