# Chase Field

Chase Field, formerly Bank One Ballpark, is a retractable-roof stadium in downtown Phoenix, Arizona. It is the ballpark of Major League Baseball's Arizona Diamondbacks. It opened in 1998, the year the Diamondbacks debuted as an expansion team. Chase Field was the first stadium built in the United States with a retractable roof over a natural grass playing surface, although it has used artificial turf since 2019.

## History

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.

### Stadium funding

In the spring of 1994, the Maricopa County Board of Supervisors approved a 0.25 percent 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.
The cost of the stadium was estimated at $279 million in 1995, but cost overruns, in part because of rising prices for steel and other materials, pushed the cost to $364 million. 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, the Tampa 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 partner Jerry Colangelo and his group.

### Since 1996

Construction on the park began in 1996, and was finished just before the Diamondbacks' first season, in 1998. 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 are Daikin Park in Houston, American Family Field in Milwaukee, Globe Life Field in Arlington, T-Mobile Park in Seattle, and LoanDepot 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 the 2001 World Series between the Arizona Diamondbacks and the New York Yankees. The Diamondbacks 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 in 1987 and 1991, both by the Minnesota Twins.
In March 2006, Chase Field played host to three first-round games of the World Baseball Classic.
Chase Field hosted the Major League Baseball All-Star Game in 2011.
Chase Field hosted the 2017 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 by Monster Jam's Jim Koehler to continue his tradition of swimming after Freestyle. The pool which opened with the stadium in 1998, was redesigned in the offseason leading up to the 2005 season.
The ballpark featured a dirt strip between home plate and the pitcher'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 and since then, Comerica Park is the only park to have one.
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 the 2008 season began, an HD 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. It is the fifth-largest HD screen in Major League Baseball behind Kauffman Stadium. The screen at Kauffman is larger in area and is square but Chase Field's screen is wider and rectangular.
Premium seating includes 4,400 club seats, 57 suites, 6 party suites, Executive suite, batters box suite, two dugout suites, and a swimming pool.
The Diamondbacks and St. 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. In 2019, leaked images of a potential new stadium by architectural firm MEIS Architects were briefly online before being removed by the firm.
The stadium hosted the third, fourth and fifth games of the 2023 World Series between the Diamondbacks and the Texas Rangers.

### Naming rights

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

## Other events

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.

### International baseball tournaments

Chase Field has hosted first-round games in the 2006 and 2013 World Baseball Classic tournaments, and hosted first round games in the 2023 tournament, from March 11, 2023, to March 15, 2023, which was postponed from 2021 due to the COVID-19 pandemic.

### College sports

The organizers of the Insight.com Bowl moved the game from Arizona 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 to Sun Devil Stadium in Tempe, to replace the Fiesta Bowl, which had moved to State Farm Stadium in Glendale. 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 the Rate Bowl due to a rebranding of the corporate sponsor.
Chase Field has staged nine women's college basketball games. The second game, played on December 18, 2006, was shortened by rain with four minutes and 18 seconds remaining and Arizona State leading Texas 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 the Tennessee Volunteers at the same facility.
In 2006, Chase Field was the site of an annual "Challenge at Chase", a college baseball game between Arizona State and University of Arizona that lasted two years. The Arizona Wildcats won both contests in 2006 and 2007.

## Roof and cooling system

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–$3.
While the ballpark had a grass surface, the roof would be kept open to expose the turf to sunlight. When necessary, it would be closed three hours before game time using two 200-horsepower motors triggered from a control room in the upper deck above left-center field. A massive HVAC system then dropped the temperature inside the park to about 78 °F (25.5 °C) by the time the gates opened. The chilled-water system, which has cooling power sufficient for 2,500 homes of 2,000 square feet (190 m$^2$), also serves more than 30 buildings in downtown Phoenix. The cooling plant, located in a separate building next to the ballpark, freezes water overnight to reduce daytime electricity demand. 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.
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.

## Transportation

Chase Field is served by westbound Valley Metro Light Rail's Washington at 3rd Street station and eastbound Jefferson at 3rd Street station.
