Baseball Story Essays - Baseball Rules, New York Yankees Players

Baseball Story Baseball has been providing us with fun and excitement for more than a hundred and fifty years. The first game resembling baseball as we know it today was played in Hoboken ,New Jersey, on June 19, 1846. The New York Nine beat the New York Knickerbokers that day, 23-1. The game was played according to rules drawn up by Alexander J. Cartwright. A surveyer and amateur athlete. It is a myth that Abner Doubleday1 invented baseball. It was Alexander Cartwright, not Abner Doubleday, who first laid out the present dimensions of the playing field and established the basic rules of the game. The first Professional baseball team was the Cincinnati Red Stockings, who toured the country in 1869 and didn't lose a game all year. Baseball began to attract so many fans that in 1876 the National league was organized-the same National league that still exists today. Although the game was played in 1876 it was recognizable as baseball-nobody would confuse it with football or basketball-it was quite a bit different from baseball as we know it now. For example, pitchers had to throw underhand, the way they still do in softball;the batter could request the pitcher to throw a "high" or "low" pitch; it took nine balls, rather than four, for a batter to get a base on balls; and the pitching distance was olny 45 feet to home plate. The rules were gradually changed over the following 20 years, until by about 1900 the game was more or less the same as it is today. In 1884, the pitchers were permitted to throw overhand; in 1887, the batter was no longer allowed to request a "high"or "low" pitch; by 1889,it took only four balls to get a batter to a base on balls; the pitching distance was legthened to sixty- feet, six inches. And since that day in 1846 There have been many greats to make up the game baseball such as Ty Cobb who was born in a small town in Georgia in 1886. He threw right-handed but batted left-handed . He held his hands a few inches apart on the bat and learned to bunt or slap line-drive hits precisely where he wanted them. He made place hitting an art. In the summer of 1905, Cobb joined a major league baseball taem, the Detroit Tigers .On August 9, Ty Cobb registered his first base hit as a member of the Tigers. In the many years to follow he added over four thousand more hits. Along with them would come a national rep- utation. Another player who some have said "changed the game", is John Roosevelt("Jackie") Robinson2.On April 15, 1947 at two o'clock that tuesday afternoon when nine Brooklyn Dodgers sprang out thier dugout to take the feild to start the 1947 baseball season. It was a memorable event in basebaall history, indeed in American history. Undoubtedly Robinson was a great ballplayer. He was National league's Rookie of the year in 1947 and its Most valuable player (MVP) in 1949. He won the election in 1962 to the Bseball Hall of Fame, the first African- American ever chosen for that honor. And perhaps the greatest ballplayer of all time was Goerge Herman (Babe Ruth). During the 1920, Ruth's first season as a New York Yankee, he hit .376, not enough to win the American league batting championship but a figure far beyond what today is registered by major leagues leaders. He also hit safely in 26 consecutive games, clubbed 9 triples and 36 doubles, and batted in 137 runs. Despite his weight of over 215, he stole 14 bases. Most remarkably, however, Ruth slugged 54 home runs for the season. Closest to him in the American League was Goerge Sisler, with 19 homers, while the National League leader recorded a total of only 15. Almost every team in both leagues registered a total number far below the 54 of Babe Ruth alone. There have been many more talented and great ball- players in the game such as Ted Williams,Leo Durocher, Hank Aaron,Mickey Mantle,Roger Maris,Willie Mays,Joe DiMaggio and all these ballplayers have done their part to shape and mold the game of Baseball. And today, we now have a new generation of ball- players like Mark McGwire who in the 1998 season hit an unpresedented 76 home runs and was closely followed by Sammie Sosa with 70 homers which in the 1920 and 30's was un-thought of un-imagnable, to even hit 15 home runs now playes can hit 15 home runs by

Begash (Kazakhstan)

Begash (Kazakhstan) Begash is a Eurasian pastoralist campsite, located in Semirchye in the piedmont zone of the Dzhungar Mountains of southeastern Kazakhstan, which was occupied episodically between ~2500 BC to AD 1900. The site is located at about 950 meters (3110 feet) above sea level, in a flat ravine terrace enclosed by canyon walls and along a spring-fed stream. Archaeological evidence at the site contains information about some of the earliest pastoralist Steppe Society communities; the important archaeobotanical evidence suggests Begash may have been on the route which moved domestic plants from the point of domestication into the broader world. Timeline and Chronology Archaeological investigations have identified six major phases of occupations. Phase 6 (cal AD 1680-1900), HistoricPhase 5 (cal AD 1260-1410), MedievalPhase 4 (cal AD 70-550), Late Iron AgePhase 3 (970 cal BC-30 cal AD), Early Iron AgePhase 2 (1625-1000 cal BC), Middle-Late Bronze AgePhase 1 (2450-1700 cal BC), Early-Middle Bronze Age A stone foundation for a single house is the earliest structure, built at Begash during Phase Ia. A cist burial, characteristic of other late Bronze Age and Iron Age kurgan burials, contained a cremation: near it was a ritual fire pit. Artifacts associated with Phase 1 include pottery with textile impressions; stone tools including grinders and micro-blades. Phase 2 saw an increase in the number of houses, as well and hearths and pit features; this last was evidence of roughly 600 years of periodic occupation, rather than a permanent settlement. Phase 3 represents the early Iron Age, and contains the pit burial of a young adult woman. Beginning about 390 cal BC, the first substantial residence at the site was built, consisting of two quadrilateral houses with central stone-lined fire-pits and hard-packed floors. The houses were multi-roomed, with stone lined postholes for central roof support. Trash pits and fire-pits are found between the houses. During Phase 4, occupation at Begash is again intermittent, a number of hearths and trash pits have been identified, but not much else. The final phases of occupation, 5 and 6, have substantial large rectangular foundations and corrals still detectable on the modern surface. Plants from Begash Within soils samples taken from the Phase 1a burial cist and associated funerary fire pit were discovered seeds of domesticated wheat, broomcorn millet and barley. This evidence is interpreted by the excavators, an assertion supported by many other scholars, as indication of a distinct route of transmission of wheat and millet from the central Asian mountains and into the steppes by the late 3rd millennium BC (Frachetti et al. 2010). The wheat consisted of 13 whole seeds of domesticated compact free-threshing wheat, either Triticum aestivum or T. turgidum. Frachetti et al. report that the wheat compares favorably to that from the Indus Valley region in Mehrgarh and other Harappan sites, ca. 2500-2000 cal BC and from Sarazm in western Tajikistan, ca. 2600-2000 BC. A total of 61 carbonized broomcorn millet (Panicum miliaceum) seeds were recovered from various Phase 1a contexts, one of which was direct-dated to 2460-2190 cal BC. One barley grain and 26 cerealia (grains unidentified to species), were also recovered from the same contexts. Other seeds found within the soil samples are wild Chenopodium album, Hyoscyamus spp. (also known as nightshade), Galium spp. (bedstraw) and Stipa spp. (feathergrass or spear grass). See Frachetti et al. 2010 and Spengler et al. 2014 for additional details. Domesticated wheat, broomcorn millet and barley found in this context is surprising, given that the people who occupied Begash were clearly nomadic pastoralists, not farmers. The seeds were found in a ritual context, and Frachetti and colleagues suggest that the botanical evidence represents both a ritual exploitation of exotic foods, and an early trajectory for the diffusion of domestic crops from their points of origin into the broader world. Animal Bones The faunal evidence (nearly 22,000 bones and bone fragments) at Begash contradicts the traditional notion that the emergence of Eurasian pastoralism was sparked by horse riding. Sheep/goat are the most prevalent species within the assemblages, as much as 75% of identified minimum number of individuals (MNI) in the earliest phases to just under 50% in Phase 6. Although distinguishing sheep from goats is notoriously difficult, sheep are much more frequently identified in the Begash assemblage than goats. Cattle are the next most frequently found, making up between 18-32% of the faunal assemblages throughout the occupations; with horse remains not present at all until ca 1950 BC, and then in slowly increasing percentages to around 12% by the medieval period. Other domestic animals include dog and Bactrian camel, and wild species are dominated by red deer (Cervus elaphus) and, in the later period, goitered gazelle (Gazella subgutturosa). Key species at the earliest Middle and Bronze age levels at Begash indicates that sheep/goats and cattle were the predominant species. Unlike other steppe communities, it seems apparent that the earliest phases at Begash were not based on horse riding, but rather began with Eurasian pastoralists. See Frachetti and Benecke for details. Outram et al. (2012), however, have argued that the results from Begash should not be considered necessarily typical of all steppe societies. Their 2012 article compared proportions of cattle, sheep and horses from six other Bronze Age sites in Kazakhstan, to show that dependence on horses seems to varied widely from site to site. Textiles and Pottery Textile-impressed pottery from Begash dated to the Early/Middle and Late Bronze ages reported in 2012 (Doumani and Frachetti) provide evidence for a wide variety of woven textiles in the southeastern steppe zone, beginning in the early Bronze Age. Such a wide variety of woven patterns, including a weft-faced cloth, implies interaction between pastoral and hunter-gatherer societies from the northern steppe with pastoralists to the southeast. Such interaction is likely, say Doumani and Frachetti, to be associated with trade networks postulated to have been established no later than the 3rd millinennium BC. These trade networks are believed to have spread animal and plant domestication out of the along the Inner Asian Mountain Corridor. Archaeology Begash was excavated during the first decade of the 21st century, by the joint Kazakh-American Dzhungar Mountains Archaeology Project (DMAP) under the direction of Alexei N. Maryashev and Michael Frachetti. Sources This article is a part of the About.com guide to the Steppe Societies, and the Dictionary of Archaeology. Sources for this article are listed on page two.
