Chase Field is the retractable-roof home of the Arizona Diamondbacks in downtown Phoenix, Arizona — the ballpark that proved you could play natural-conditions baseball in a desert where summer highs regularly clear 110°F. Since opening in 1998, it has hosted two World Series, an All-Star Game, and one of MLB’s most famous novelty features: a swimming pool beyond the right-center-field wall.
If you’re planning a visit or just chasing the numbers — field dimensions, seating capacity, where to park, what you can bring in, or exactly what to call the Diamondbacks’ stadium — here’s the complete, up-to-date breakdown, along with the history and quirks that make it one of baseball’s most distinctive parks.

Chase Field Dimensions
Chase Field’s outfield is a fairly standard modern MLB shape, but with a deep, sweeping true center field. Distances from home plate: 330 feet down the left-field line, 374 feet to left-center, out to a deep left-center pocket of 413 feet, 407 feet to dead-center field, 413 feet at the deep right-center pocket, 374 feet to right-center, and 335 feet down the right-field line.
The outfield wall stands 25 feet tall in center field — one of the taller center-field walls in the majors — which occasionally turns would-be home runs into off-the-wall doubles. The park’s large foul territory is also part of its identity: a sizable share of seats sit well back from the foul lines rather than wrapped tightly around the field, a design choice that pushed the upper deck higher than many parks built in the same era. That extra room in foul ground is also why routine pop-ups occasionally get away from infielders that would be caught in tighter ballparks.
Chase Field Seating Capacity & Seating Chart
Chase Field’s current seating capacity is 48,263, a figure that has held since a set of renovations completed in 2023. Capacity has shifted several times over the ballpark’s history: it opened at roughly 48,500 seats in 1998, expanded during the early-to-mid 2000s, and has been trimmed gradually since through premium-seating and berm reconfigurations.
Seating is arranged across three main levels on the official seating chart. The 100 Level (field level) runs from Infield and Baseline Box seats near the dugouts out to the Bullpen Reserve and outfield bleacher sections. The 200 Level is the Club Level, home to the ballpark’s suites and Club Box/Club Reserve seating that wraps from the left-field corner to the right-field corner. The 300 Level is the Outfield and Infield Reserve upper deck, the highest seating tier in the park thanks to Chase Field’s extended foul territory.
The ballpark’s most talked-about seats aren’t numbered at all: the Pool Suite in right-center field holds a swimming pool and hot tub that can be rented out by a group for the game, typically accommodating a few dozen guests at once along with catering, towels, and a private concierge. Pricing moves with demand — it’s been reported in the roughly $4,750-to-$7,000-per-game range for most regular-season dates, climbing dramatically for marquee games like the World Series — so check the team’s official site for the exact current rate before booking.
Naming History: Bank One Ballpark to Chase Field
The Diamondbacks’ stadium has gone by a few names since it opened in 1998, which is why searches for ‘D-backs stadium’ or ‘Chase Field Arizona’ sometimes turn up conflicting results. It debuted as Bank One Ballpark — nicknamed ‘The BOB’ — and was renamed Chase Field in September 2005 after JPMorgan Chase acquired Bank One and its naming rights.
There is only one Diamondbacks ballpark; Bank One Ballpark, Chase Field, ‘The BOB,’ and ‘D-backs Stadium’ all refer to the same building at 401 E. Jefferson Street in downtown Phoenix.
A Desert Engineering Marvel
When Chase Field opened in 1998, its retractable roof was unlike anything baseball had seen. Powered by two 200-horsepower motors, the roof takes roughly four and a half minutes to open or close, and the stadium’s HVAC system cools the interior well below the outdoor temperature by first pitch — a necessity when Phoenix summer highs routinely exceed 110°F. The roof spans enough area to cover the entire playing field plus the seating bowl, making day games and night games alike playable in climate-controlled comfort.
The field itself has evolved over the years. Natural grass served as the playing surface from the stadium’s debut through the 2018 season, before artificial turf from Shaw Sports Turf was installed ahead of 2019 — a practical response to the difficulty of maintaining live grass under a partially closed roof. A new, significantly larger scoreboard was added ahead of the 2026 season, modernizing the fan experience while preserving the park’s distinctive character.
World Series History and Iconic Moments
Chase Field earned a permanent place in baseball lore during the 2001 World Series, hosting Games 1, 2, 6, and 7 between the Arizona Diamondbacks and the New York Yankees. The Diamondbacks won all four home games and claimed the championship in seven games, denying the Yankees a fourth consecutive title. Game 7’s walk-off hit in the bottom of the ninth inning remains one of the most dramatic finishes in World Series history.
The stadium returned to the Fall Classic in 2023, hosting Games 3, 4, and 5 between the Diamondbacks and the Texas Rangers. Beyond the World Series, Chase Field has welcomed the MLB All-Star Game in 2011 and served as a World Baseball Classic venue in 2006, 2013, and 2023, cementing its status as one of the sport’s premier stages.
Planning Your Visit: Tickets, Parking & Bag Policy
Tickets are sold in tiers that mirror the seating chart — Infield and Baseline Box closest to the field, Club Level seats and suites around the second deck, and Outfield/Infield Reserve and bleacher seating in the upper and outfield sections. Prices vary by opponent, day of week, and how close the date is to the game, so the most reliable way to see current pricing and availability is through the team’s official ticketing page rather than a guess here.
Parking surrounds Chase Field in a mix of team-operated and private garages and surface lots within a few blocks of downtown Phoenix, generally running from single-digit dollar amounts for the farthest lots up to several times that for covered garages closest to the gates. Booking a spot online in advance through the team’s official parking partner is usually cheaper than paying at the gate, and some lots are cash-only, so it’s worth checking payment options before you drive in.
Chase Field uses a clear-bag policy: bags must generally be clear plastic, vinyl, or PVC and no larger than roughly 12 x 6 x 12 inches (a one-gallon clear freezer bag is also fine), or a small non-clear clutch purse. Backpacks and luggage aren’t permitted inside, and the ballpark does not run its own bag check, so leave oversized or non-compliant bags at your hotel or car. For the exact current hours, gate times, ticket prices, parking rates, and bag-policy specifics, always check the official Arizona Diamondbacks site before you go, since these details can change season to season.
