History

   This $354 million ballpark has become one of the game's most recognizable landmarks.  It is baseball-only, which is nice, and the sight lines may be the best in the majors - 80 percent of the seats are inside the foul poles, and there is no upper deck around the outfield.  Also, it proves that natural grass can co-exist with a dome stadium - Miller Park went the same route in 2001.

   Bank One has all the modern conveniences - air conditioning, a retractable roof,and a signature swimming pool behind the right field wall where the bikini-clad celebrate Diamondback home runs.  The 8,000 ton cooling system is the equivalent of air-conditioning for more than 2,500 typical Arizona homes.  A parking and traffic circulation study conducted for the Maricopa County Stadium District identified approximately 18,600 parking spaces within a 15-minute walk of the stadium.

   But it also has a lot of classic touches.  Most visible is the dirt path between the pitchers mound and homeplate, reminiscent of fields 100 years ago; but the quirky angles around the foul poles and the towering, distinctive wall in center are also classic touches.  The traditional look of red brick and green structural steel blends into its surroundings; many of the design details are borrowed from the warehouse district that surrounds the Ballpark.

 

The roof: The roof opens to various positions to make sure a proper amount of sunlight hits the natural turf without heating the concrete and metal within the stadium, thus allowing it to cool quickly and efficiently. With the roof in the closed position, the minimum height over the playing surface is 180 feet and the maximum height is 200 feet.

   Even though more than half of the Diamondbacks' games are played with the retractable room in a closed position, the turf receives sunlight at every opportunity. Even on game days, the roof remains open into the afternoon to allow maximum exposure. When areas of the field receive too little natural sunlight, large incandescent growth lights provide a substitute.

 

Playing Field: After experimenting with other turfs The Bank One Ballpark finally settled on Bull's Eye bermuda, which was installed during the All-Star break in 1999. The 2000 season will feature Bull's Eye Bermuda overseeded with Kentucky blue grass and perennial rye grass.

 

The pool: In recreating an upscale Arizona backyard, the Pavilion gives about 35 guests the opportunity to see the Diamondbacks play while enjoying a swimming pool, hot tub, fountains, catering and other amenities.  The Pavilion is located next to the outfield wall in right-center. With the pool approximately 415 feet from home plate, home runs occasionally make a splash. When a Diamondback homers, water cannons celebrate by firing streams 30 to 35 feet into the air.

 

 

Analysis

 

   With an elevation of approximately 1,100 feet above sea level, Bank One Ballpark is the second-highest facility in the major leagues, trailing only Coors Field in Denver. Scientists have estimated that a fly ball will travel seven feet farther for every 1,000 feet of altitude.  When the hot desert air blows in, the heat makes the ball travel even further.

   That said, the park doesn't appear to boost run production significantly - in fact, it has depressed home runs in three of the past four years, and played neutral as far as scoring runs is concerned.  The center field wall is a goodly 407 feet away, and the 25-foot wall there is hard to clear; in addition, the walls slope steeply away from the already longish power alleys towards center field, so that the wall is actually 413 feet away from the plate at its furthest points, about 20 feet to the left and right of dead center.

   In addition to the length of the lines, the roof is typically closed from mid-May to nearly the end of the season, because of the summer desert heat.  The ball doesn't carry nearly as well at these times - in 1998, scoring and homers increased by 21 percent and 28 percent respectively when the roof was open.

   The quirky angles around the foul poles, where the fences angle away steeply by about 30 feet, and the large distance from alley to alley makes for a lot of triples.

 

Defense: The large outfield puts a premium on outfielders with range.  A center fielder who can chase fly balls, and who gets a good jump on the ball, is a huge asset.  The corner outfielders have to be competent athletes, because the ball takes difficult and quirky bounces around the oddly shaped foul pole fences.  The shorter walls in left and right field make it possible for a good outfielder to leap and take away a home run.

   The team is still struggling to make natural grass grow well in an enclosed stadium.  In 1998, the outfield grass didn't grow well, making bad hops a concern, though the infield grass seemed to play well.  The strain of Bermuda grass was given to all kinds of dead spots in the outfield and large divots late in the season.  In 1999, a new strain of grass seemed to grow better, and the outfield played substantially better.  Over the three years that the park has been around, errors have actually been suppressed by almost 50% in the outfield.

Who benefits: Flyball pitchers benefit the most when the ball isn't carrying well because they can feel free to get the ball up in the strike zone, since hitters seem to have trouble clearing the distant walls.  Pitchers who change speeds and can force extreme pulls fare even better.  Curt Schilling, who gave up a league-leading 37 homers, fits the former profile, but actually did better on the road: 11-2, 2.82 ERA on the road vs. 11-4, 3.13 ERA at home.  Randy Johnson also did marginally better on the road - 9-3, 2.43 ERA on the road vs. 12-3, 2.54 ERA at home.

     Luis Gonzalez hit .342 at home and .308 on the road, but hit 31 of his 57 HR on the road.  Damian Miller hit .305 at home vs. .243 on the road, with 9 of his 13 dingers at the BOB.

 

Who gets hurt:  Power hitters and home run guys, especially moderate ones, when the roof closes. Matt Williams and right-handed hitters had the worst home-road splits of any D'back hitter last season.
