Chase Field, formerlyBank One Ballpark, is aretractable roofstadium in downtownPhoenix, Arizona, United States. It is theballpark ofMajor League Baseball'sArizona Diamondbacks. It opened in1998, the year the Diamondbacks debuted as anexpansion team. Chase Field was the first stadium built in the United States with aretractable roof over a natural grass playing surface, although it has usedartificial turf since 2019.

The park was built during a wave of new, baseball-only parks in the 1990s. Although nearly all of those parks were open-air, it was taken for granted that a domed stadium was a must for a major-league team to be viable in the Phoenix area. Phoenix is by far the hottest major city in North America; the average high temperature during baseball's regular season is 99.1 °F (37.3 °C), and game-time temperatures well above 100 °F (38 °C) are common during the summer.

In the spring of 1994, theMaricopa CountyBoard of Supervisors approved a 0.25 percentage point increase in the county sales tax to pay for their portion of the stadium funding. That happened during a huge county budget deficit and lack of funding for other services. The sales tax was very unpopular with local citizens, who were not permitted to vote on funding a baseball stadium with general sales tax revenue (use of public subsidies for stadium projects was prohibited by a 1989 referendum). The issue was so controversial and divisive that, in August 1997, Maricopa County Supervisor Mary Rose Wilcox was shot and injured while leaving a county board meeting by Larry Naman, a homeless man, who attempted to argue in court that her support for the tax justified his attack. In May 1998, Naman was found guilty of attempted first-degree murder.^[13]

The cost of the stadium was estimated at $279 million in 1995,^[14] but cost overruns, in part because of rising prices for steel and other materials, pushed the cost to $364 million.^[15] As part of the stadium deal, the Diamondbacks were responsible for all construction costs over $253 million. The extra expenses, combined with the Diamondbacks and the other expansion franchise, theTampa Bay Devil Rays, not being allowed to share in national MLB revenue for their first five years of operations, left the Diamondbacks in a less-than-desirable financial situation, which came back to haunt team founder and managing partnerJerry Colangelo and his group.

Construction on the park began in 1996, and was finished just before the Diamondbacks' first season, in1998. It was the third MLB stadium to have a retractable roof and the first in the United States (at the time, only Toronto's SkyDome (Rogers Centre) and Montreal's Olympic Stadium had them; others since areDaikin Park in Houston,American Family Field in Milwaukee,Globe Life Field in Arlington,T-Mobile Park in Seattle, andLoanDepot Park in Miami). It was also the first ballpark to feature natural grass in a retractable roof stadium.

The stadium hosted Games 1, 2, 6, and 7 of the2001 World Series between the Arizona Diamondbacks and theNew York Yankees. TheDiamondbacks won all four home games, winning the title in seven games, and thus denying the Yankees a fourth consecutive championship. It was only the third time that the home team won all games of a World Series, with the other two instances occurring in1987 and1991, both by theMinnesota Twins.

In March 2006, Chase Field played host to three first-round games of theWorld Baseball Classic.

Chase Field hosted theMajor League Baseball All-Star Game in2011.^[16]

Chase Field hosted the2017 National League Wild Card Game between the Diamondbacks and Colorado Rockies. This was the D-Backs' first appearance in the postseason as a Wild Card team. The D-Backs won 11–8 and advanced to the 2017 NLDS against the Los Angeles Dodgers but were swept in three games. Game 3 was held at Chase Field, when the D-Backs lost 3–1.

Chase Field has a swimming pool located in right-center field, which is rented to patrons as a suite holding 35 guests for $3,500 per game during the 2011 season.Mark Grace was the first player to hit a home run into the pool. Besides baseball, the pool has been used byMonster Jam's Jim Koehler to continue his tradition of swimming after Freestyle.^[17] The pool which opened with the stadium in 1998, was redesigned in the offseason leading up to the2005 season.^[18]

The ballpark featured a dirt strip betweenhome plate and thepitcher's mound until 2019. This dirt strip, sometimes known as the "keyhole", was very common in old-time ballparks up to 1938. The dirt strip was removed when synthetic turf was installed.Comerica Park was the only other park to have one until 2025.

The park's foul territory is somewhat larger than that for most ballparks built in the 1990s. With 80% of the seats in foul territory, the upper deck is one of the highest in the majors. The park's suites are tucked far under the third deck, which keeps the upper deck closer to the action, with the exception of the Dugout Suites which sit next to the home and visitor's dugouts.

Before the2008 season began, anHD scoreboard was installed beyond center field, replacing the original. The new scoreboard is 46 ft (14 m) high and 136 ft (41 m) wide and cost $14 million. At the time, it was the fifth-largest HD screen in Major League Baseball, behindKauffman Stadium. The screen at Kauffman is larger in area and is square, but Chase Field's screen is wider and rectangular.^[19][20]

Premium seating includes 4,400 club seats, 57 suites, 6 party suites, Executive suite, batters box suite, two dugout suites, and a swimming pool.

TheDiamondbacks andSt. Louis Cardinals game on September 24, 2019, was the longest game in Chase Field's history. It lasted six hours and 53 minutes, involving 19 innings.

On October 12, 2018, the Diamondbacks announced that they would replace their natural grass surface with a synthetic surface from Shaw Sports Turf for the 2019 season.^[21] In 2019, leaked images of a potential new stadium by architectural firm MEIS Architects were briefly online before being removed by the firm.^[22]

The stadium hosted the third, fourth and fifth games of the2023 World Series between theDiamondbacks and theTexas Rangers.

In September 2025, Arizona House Bill 2704 was formally signed into law which would allow sales tax dollars to fund renovations of the stadium.^[23]

The stadium was called Bank One Ballpark whenBank One of Chicago, Illinois (who had acquired locally basedValley National Bank of Arizona in 1992), purchased naming rights for $100 million over 30 years. After Bank One merged with New York-basedJPMorgan Chase & Co. in 2005, Chase assumed the naming rights and the stadium's name was changed to Chase Field.^[24]

The stadium hosts occasional concerts and international soccer games. For football and soccer, the field is set up with the end lines perpendicular to the third-base line and temporary bleachers added on the east side.

Chase Field has hosted first-round games in the2006 and2013World Baseball Classic tournaments, and hosted first round games in the2023 tournament, from March 11, 2023, to March 15, 2023, which was postponed from 2021 due to theCOVID-19 pandemic.^[25]

The organizers of theInsight.com Bowl moved the game fromArizona Stadium in Tucson to Phoenix beginning in December 2000, and Chase Field became the game's host. After hosting six editions of the game, the bowl game moved toSun Devil Stadium in Tempe, to replace theFiesta Bowl, which had moved toState Farm Stadium inGlendale. The bowl, which has undergone several naming changes, remained in Tempe for nine playings, then returned to Chase Field starting with the January 2016 edition. In October 2024, the game was renamed as theRate Bowl due to a rebranding of the corporate sponsor.^[26]

Chase Field has staged ninewomen's college basketball games. The second game, played on December 18, 2006, was shortened by rain with four minutes and 18 seconds remaining andArizona State leadingTexas Tech 61–45. Venue staff closed the roof in an effort to finish the game, but officials deemed the court unsafe. In 2000, ASU played theTennessee Volunteers at the same facility.^[27]

In 2006, Chase Field was the site of an annual "Challenge at Chase", a college baseball game betweenArizona State andUniversity of Arizona that lasted two years. The Arizona Wildcats won both contests in 2006 and 2007.^[28][29]

In February 2006, theProfessional Bull Riders hosted aBuilt Ford Tough Series bull riding event at this venue.Chris Shivers won this event with a total score of 181.5 points (out of a possible 200) on two bulls, including an impressive 93.75 (out of 100) points on Taylor Made bucking bull, Smokeless Wardance, in the short-go round. During the long-go round, the roof was closed, but during the short-go, the roof was opened.

The stadium has hosted Monster Energy Supercross rounds from 1999 to 2015.^[30]Monster Jam came to Chase Field every year in late January about two weeks after Monster Energy Supercross. Both events moved to theUniversity of Phoenix Stadium in 2016.

WWE hosted theRoyal Rumble at Chase Field on January 27, 2019, marking nearly 16 years that a WWE event was held at a baseball stadium sinceWrestleMania XIX at Safeco Field in Seattle and the first Royal Rumble to be held outdoors.^[31]

Chase Field's roof is opened or closed depending on the game-time temperature. Even with the roof closed, the park's windows allow enough sunlight to play in daylight without overheating the stadium. The roof takes about 4½ minutes to open or close at a cost of $2–$3.

While the ballpark had a grass surface, the roof would be kept open to expose the turf to sunlight. When necessary, it would be closed three hours before game time using two 200-horsepower motors triggered from a control room in the upper deck above left-center field.^[16] A massiveHVAC system then dropped the temperature inside the park to about 78 °F (25.5 °C) by the time the gates opened. The chilled-water system, which has cooling power sufficient for 2,500 homes of 2,000 square feet (190 m²), also serves more than 30 buildings in downtown Phoenix.^[16] The cooling plant, located in a separate building next to the ballpark, freezes water overnight to reduce daytime electricity demand.^[16] Originally, the HVAC system did not cool above row 25 of the upper level, exposing fans in the higher rows to the brunt of Phoenix' oppressive summer heat. Subsequent improvements kept virtually all of the facility in air-conditioned comfort.^[32]Following the introduction of a synthetic playing surface, the roof is kept mostly closed and is opened only on game days when weather permits, greatly reducing the facility's demand on the HVAC system.
