Problem: Background: Born in Dusseldorf, West Germany, Kaymer turned professional at age 20 in 2005 and is a member of the European Tour. He has won eleven tournaments on the tour including four in 2010 to win for the first time the Race to Dubai, formerly the Order of Merit. Among those wins was the PGA Championship in the United States, which made him only the second German (after Bernhard Langer) to win a major championship. He also won the WGC-HSBC Champions to become the tenth player to win both a major title and a World Golf Championship event.
Context: In May 2014, Kaymer earned a wire-to-wire win at The Players Championship in Ponte Vedra Beach, Florida, finishing -13 for a one-shot victory over runner-up Jim Furyk. He started the week with a course record-tying 63 in the first round at the Stadium Course of TPC at Sawgrass, joining Fred Couples (1992), Greg Norman (1994), and Roberto Castro (2013). He played the front nine (his second nine) in 29 (-7). This was the first time ever, back or front nine, that a player shot below 30 through nine holes at The Players. The final round was delayed due to bad weather while Kaymer was playing the 14th hole. He holed a difficult 28-foot (8.5 m) par putt (with a huge downhill left-to-right-break) on the 17th green to retain his one-stroke lead. His approach shot on 18 was short of the green but he holed the winning putt for par in near darkness and avoided a three-hole playoff. He became the fourth European to win this event (Sandy Lyle in 1987, Sergio Garcia in 2008, and Henrik Stenson in 2009), and is the fourth to win a major, a World Golf Championship, and The Players, joining Tiger Woods, Adam Scott, and Phil Mickelson. Kaymer earned a winner's share of $1.8 million, the largest of his career, and re-entered the top 50 in the Official World Golf Ranking, rising 33 places from 61st to 28th.  In June, Kaymer started the U.S. Open at Pinehurst with consecutive rounds of 65 (-5) to set a U.S. Open record for 36 holes (130). He finished at 271 (-9), eight strokes ahead of runners-up Rickie Fowler and Erik Compton, and became the first player in history to win those two championships back to back. (Woods also held both titles concurrently, winning the U.S. Open in 2000 and The Players in March 2001; it moved to May in 2007.) With the win, Kaymer gained exempt status on the PGA Tour through 2019 and rose to eleventh in the world rankings. With his U.S. Open victory in 2014, Martin became the first non-British European golfer ever to win the U.S. Open, and one of few players to win two majors under the age of thirty.  In October 2014, Kaymer won the PGA Grand Slam of Golf, the annual 36-hole event featuring the year's four major champions.

Background: Abner Doubleday (June 26, 1819 - January 26, 1893) was a career United States Army officer and Union general in the American Civil War. He fired the first shot in defense of Fort Sumter, the opening battle of the war, and had a pivotal role in the early fighting at the Battle of Gettysburg. Gettysburg was his finest hour, but his relief by Maj. Gen. George G. Meade caused lasting enmity between the two men.
Context: Although Doubleday achieved minor fame as a competent combat general with experience in many important Civil War battles, he is more widely known as the supposed inventor of the game of baseball, in Elihu Phinney's cow pasture in Cooperstown, New York, in 1839.  The Mills Commission, chaired by Abraham G. Mills, the fourth president of the National League, was appointed in 1905 to determine the origin of baseball. The committee's final report, on December 30, 1907, stated, in part, that "the first scheme for playing baseball, according to the best evidence obtainable to date, was devised by Abner Doubleday at Cooperstown, New York, in 1839." It concluded by saying, "in the years to come, in the view of the hundreds of thousands of people who are devoted to baseball, and the millions who will be, Abner Doubleday's fame will rest evenly, if not quite as much, upon the fact that he was its inventor ... as upon his brilliant and distinguished career as an officer in the Federal Army."  However, there is considerable evidence to dispute this claim. Baseball historian George B. Kirsch has described the results of the Mills Commission as a "myth". He wrote, "Robert Henderson, Harold Seymour, and other scholars have since debunked the Doubleday-Cooperstown myth, which nonetheless remains powerful in the American imagination because of the efforts of Major League Baseball and the Hall of Fame in Cooperstown." At his death, Doubleday left many letters and papers, none of which describe baseball or give any suggestion that he considered himself a prominent person in the evolution of the game, and his New York Times obituary did not mention the game at all. Chairman Mills himself, who had been a Civil War colleague of Doubleday and a member of the honor guard for Doubleday's body as it lay in state in New York City, never recalled hearing Doubleday describe his role as the inventor. Doubleday was a cadet at West Point in the year of the alleged invention and his family had moved away from Cooperstown the prior year. Furthermore, the primary testimony to the commission that connected baseball to Doubleday was that of Abner Graves, whose credibility is questionable; a few years later, he shot his wife to death and was committed to an institution for the criminally insane for the rest of his life. Part of the confusion could stem from there being another man by the same name in Cooperstown in 1839.  Despite the lack of solid evidence linking Doubleday to the origins of baseball, Cooperstown, New York became the new home of what is today the National Baseball Hall of Fame and Museum in 1937.  There may have been some relationship to baseball as a national sport and Abner Doubleday. While the modern rules of baseball were formulated in New York during the 1840s, it was the scattering of New Yorkers exposed to these rules throughout the country, that spread not only baseball, but also the "New York Rules", thereby harmonizing the rules, and being a catalyst for its growth. Doubleday was a high-ranking officer, whose duties included seeing to provisions for the US Army fighting throughout the south and border states. For the morale of the men, he is said to have provisioned balls and bats for the men.
