The United States Amateur Championship, commonly known as the U.S. Amateur, is the leading annual golf tournament in the United States for amateur golfers. It is organized by the United States Golf Association and is currently held each August over a 7-day period. In 1894 there were two tournaments called the "National Amateur Championship". One of them was played at Newport Country Club and was won by William G. Lawrence, and the other took place at Saint Andrew's Golf Club and was won by Laurence B. Stottard. This state of affairs prompted Charles B. Macdonald of the Chicago Golf Club to call for the creation of a national governing body to authorize an official national championship, and the Amateur Golf Association of the United States, which was soon to be renamed the United States Golf Association, was formed on December 22 of that year. In 1895 it organized both the first U.S. Amateur Championship and the first U.S. Open, both of which were played at Newport Country Club. There are no age or gender restrictions on entry, but players must have a handicap index of 2.4 or less. Originally, entry was restricted to members of USGA-affiliated private clubs (and, presumably, international players who were members of private clubs affiliated with their nations' golf governing bodies), a restriction that was not lifted until 1979. The tournament consists of two days of stroke play, with the leading 64 competitors then playing a knockout competition held at match play to decide the champion. All knockout matches are over 18 holes except for the final, which consists of 36 holes, separated into morning and afternoon 18-hole rounds. Nowadays it is usually won by players in their late teens or early twenties who are working towards a career as a tournament professional. Before World War II more top-level golfers chose to remain amateur, and the average age of U.S. Amateur champions was higher. Many of the leading figures in the history of golf have been U.S. Amateur Champion, including Bobby Jones five times, Jerome Travers four times, Jack Nicklaus twice and Tiger Woods three times (all consecutive; the only player to win three in a row). Woods' first win, as an 18-year-old in 1994, made him the youngest winner of the event, breaking the previous record of 19 years 5 months set by Robert Gardner in 1909. In 2008, New Zealander Danny Lee became the
