Jeff Quinney returns as the defending champion. Quinney beat James Driscoll in 39 holes last year to take the prize at the Baltusrol Golf Club in New Jersey. The winning shot came on a most-dramatic 30-foot birdie putt.
The U.S. Amateur has had plenty of other dramatic moments over the years.
In fact, the event is the oldest existing golf championship in the United States, dating back to 1895. It is officially one day older than the United States Open.
Some of the past champions have had last names of Nicklaus, Palmer, Mickelson and Sutton. Tiger Woods is the most recent great Amateur champion, as he took three titles in a row from 1994 through 1996.
Bobby Jones was the greatest golfer in the events history, however, and he attracted the majority of the media attention that the championship sees today. Jones won the Amateur five times, with his last in 1930 a part of the now-famous Grand Slam.
In addition to the U.S. Amateur that year, Jones also took the U.S. Open, the British Amateur and the British Open.
This week, players will begin their golf on Monday and Tuesday with the stroke play qualifying portion of the event. Following a cut of the low 64 scorers, the championship advances into match play. The final match is played in 36 holes.
