Ballpark
A ballpark, or baseball park, is a type of sports venue where baseball is played. The playing field is divided into two field sections called the infield and the outfield. The infield is an area whose dimensions are rigidly defined in part based on the placement of bases, and the outfield is where dimensions can vary widely from ballpark to ballpark. A larger ballpark may also be called a baseball stadium because it shares characteristics of other stadiums.
General characteristics
The playing field
A baseball field can be referred to as a diamond. The infield is a rigidly structured diamond of dirt and grass containing the three bases, home plate, and the pitcher's mound. The space between the bases and home is normally a grass surface, save for the dirt mound in the center. Some ballparks have grass or artificial turf between the bases, and dirt only around the bases and pitcher's mound. Others, such as Koshien Stadium in Hyōgo Prefecture, Japan, have an infield of entirely dirt.Two white lines extend from the home plate area, aligned with the first and third bases. These are the foul lines or base lines, usually differentiated by referring to them as the first base line, or the third base line. If a ball hit by the batter lands outside of the space between these two lines or rolls out of this space before reaching first or third base, the ball is "foul". If it lands between or on the lines, it is "fair". At the end of the lines are two foul poles, which help the umpires judge whether a ball is fair or foul. These "foul poles" are actually in fair territory, so a ball that hits them on the fly is a home run.
On either side of home plate are the two batter's boxes This is where the batter stands when at bat. Behind home is the catcher's box, where the catcher and the home plate umpire stand.
Next to the first and third base are two coaches' boxes, where the first and third base coaches guide the baserunners, generally with gestures or shouts. As the baserunner faces away from the outfield when running from second base to third, they cannot see where the ball is and must look to the third base coach on whether to run, stop, or slide.
Farther from the infield on either side are the dugouts, where the teams and coaches sit when they're not on the field. They are named such because, at the professional levels, this seating is below the level of the playing field to not block the view from prime spectator seating locations. In amateur parks, the dugouts may be above-ground wooden or CMU structures with seating inside, or simply benches behind a chain-link fence.
Beyond the infield and between the foul lines is a large grass outfield, generally twice the depth of the infield. The playing field is bordered by fences of varying heights. The infield fences are in foul territory, and a ball hit over them is not a home run; consequently, they are often lower than the outfield fences to provide a better view for spectators. Sometimes, the outfield fence is made higher in certain areas to compensate for close proximity to the batter.
In many parks, the field is surrounded by an area roughly wide made of dirt or rubberized track surface called a "warning track". In the 1937 refurbishment of the original Yankee Stadium, a running track that ran the perimeter of the field was incorporated into the field of play as the first warning track. MLB formalized the warning track as a requirement in 1949.
Beyond the outfield fence in professional parks is an area called the batter's eye. To ensure the batter can see the white ball, the batter's eye contains no seating and is darker in color. The batter's eye area can be anything from a dark wall to a grassy slope.
Most major league ballparks are oriented with the central axis of the playing field running toward the north or east or some direction between. Major League Baseball Rule 1.04 states that it is "desirable" that the central axis run east-northeast. This is to prevent the setting sun from being in the batter's eyes. In practice, major league parks vary up to about 90 degrees from east-northeast in either direction, but none face west, except for a few which are oriented just slightly west of straight north.
Seating
Today, in Major League Baseball, a multi-tiered seating area, a grandstand, surrounds the infield. How far this seating extends down the baselines or around the foul poles varies from park to park. In minor league parks, the grandstands are notably smaller, proportional to expected sizes of crowds compared with the major leagues.The seating beyond the outfield fence generally differs from the grandstand, though some multi-purpose or jewel box parks have the grandstand surround the entire field. This area could contain inexpensive bleacher seats, smaller grandstands, or simply inclined seating. In local ballparks, there are often simply a set or two of aluminum bleachers on the first-base and third-base sides.
Variations
Distinctive from "goal games" such as football and basketball, which have fixed-size playing areas, the infield is the only rigidly laid-out part of the field. Like its English relative, cricket, there is significant flexibility in the shape and size of the rest of the playing area.Baseball leagues may specify a minimum distance from home plate to the outfield fences. Generally, the higher the skill level, the deeper the minimum dimensions must be, to prevent an excess of home runs. In the major leagues, a rule was passed in 1958 that compelled any new fields built after that point to have a minimum distance of from home plate to the fences in left and right field, and to center.. This rule was passed to avoid situations like the Los Angeles Coliseum, which was. down the left field line.
However, with the opening of Baltimore's Camden Yards, the "minimum distance" rule began to be ignored. One factor may be that the quaint, "retro" look of Camden Yards, with its irregular measurements, proved to be very popular, along with a traditionalist backlash against the symmetrical, multi-purpose, "cookie-cutter" stadiums. Since the opening of Camden Yards, many other "retro" stadiums have been built, each with asymmetrical fences. These distances vary from park to park, and can even change drastically in the same park. One of the most famous examples is the original Yankee Stadium, whose odd-shaped plot of land caused right field to be over shorter than left, although this difference lessened over time. The rectangular Polo Grounds had extremely short distance down the lines,. to right and. to left. In contrast, the deepest part of center field was nearly. from home plate.
Older ballparks, such as Fenway Park, were grandfathered in and allowed to keep their original dimensions. Also, new parks have sometimes received special dispensation to deviate from these rules. For instance, the second Yankee Stadium, built 2009, used the same dimensions as the original Yankee Stadium.
The heights of the fences can also vary greatly, the most famous example being the -high Green Monster in Fenway Park's left field. Such tall fences are often used to stop easy home runs in a section of the ballpark where the distances from home are shorter, or where there is little space between the field and the street beyond. Some in-play scoreboards and high fences reached 50 to, whereas a few outfields were even lined with hedges rather than normal fences or walls. The Hubert H. Humphrey Metrodome, when set up for baseball, had a right field "fence" that was actually a relatively thin blue plastic sheet covering folded up football seats. It was often called a "baggie" or "Hefty bag".
Some ballparks have irregularly shaped fences. Ballparks may have round swooping fences or rigidly angled fences, or possibly a significant change in direction or irregular angle. For example, the center field stands and the left field stands at Fenway Park meet at an uneven angle, creating an indentation that angles sharply back into the stands. In Citi Field and Oracle Park, part of the right field fence juts unevenly into the outfield as if the builders were trying to create an unpredictable ricochet effect for balls hit against it. Some "retro" parks, such as Globe Life Park in Arlington, throw in a sudden and small inward turn just to give a little quirkiness to the design. Milwaukee's Miller Park was designed, with the help of former player Robin Yount, to promote extra base hits.
Originally these variations resulted from the shape of the property where the park was constructed. If there was a street beyond left field, the distance to the left field fence would be shorter, and if the distance was too short, the fence would be higher. For example, in the old Griffith Stadium in Washington, D.C., part of center field had to be built around a cluster of apartment houses and the result was a rather large angular indentation in the left-center field fence. Now, these variations are mostly influenced by the specifications and whims of the designers. New "retro" parks, which try to recapture the feel of the jewel box parks, are often designed to have these quirks.
Etymology
Baseball was originally played in open fields or public parks. The genesis of modern baseball is conventionally connected with Elysian Fields in Hoboken, New Jersey, a large public park where the businessmen of New York City gathered from time to time to play organized baseball games and cricket matches, starting around the mid-1840s. The name "Field" or "Park" was typically attached to the names of the early ballparks.With the beginnings of professional baseball, the ballfield became part of a complex including fixed spectator seating areas, and an enclosure to restrict access to paying customers, as with a fairgrounds. The name "Grounds" began to be attached to ballparks, starting with the Union Grounds in 1862. The suffixes "Field" and "Park" were still used, but many professional ballparks were "Grounds". The last major league "Grounds" was the Polo Grounds in New York City, which was razed in 1964.
The term "stadium" has been used since ancient times, typically for a running track and its seating area. As college football gained in popularity, the smaller college playing fields and running tracks gave way to large stadiums, many of them built during the sport's "boom" of the 1920s. Major league baseball enjoyed a similar boom. One of the first major league ballparks to be called a "stadium" was actually the Polo Grounds, which was temporarily renamed Brush Stadium from its reconstruction in 1911 until the death of owner John T. Brush in the 1920s. By then, the most famous baseball "stadium" of them all had been constructed: Yankee Stadium. From that point until the retro building boom of the 1990s, the suffix "Stadium" was used for almost every new major league venue, and was sometimes applied to the old ones, such as Shibe Park, which was renamed Connie Mack Stadium in 1954.
The suffix "Dome" was also used for the indoor stadiums constructed from the 1960s onward. The official names of those arenas also often included the word "Stadium", such as the Houston Astrodome, whose formal name was "Harris County Domed Stadium" in 1965; the Kingdome, whose formal name was "King County Domed Stadium", and the Metrodome, for which the Minneapolis highway signs directed the driver to "Metrodome Stadium". The retro era of the 1990s and early 2000s saw some venues return to using "park" in a stadium's name, even in domed structures such as T-Mobile Park and American Family Field.
There is little consistency in the choice between "Field" and "Park". For example, Houston's Daikin Park was originally named "Enron Field".
