Camilo Villegas (Spanish pronunciation: [kaˈmilo βiˈʎeɣas]; born 7 January 1982) is a Colombian professional golfer who plays on the PGA Tour and the European Tour.

Villegas was born in Medellín, Colombia, and took up golf as a child. After several different National Junior Championships in Colombia in the ages between 8 and 15, at 16 he became the first player in Colombian golf history to win the Amateur's Grand Slam in the same year: The National Junior Championship (stroke play), the National Junior Championship (match play), the National Amateur Championship, and the Colombian Open in the amateur category. Then, in 2001, he became only the second player to win the Colombian Open as an amateur. His success in Colombian golf throughout the 1990s earned him the distinction of "Player of the Decade" issued by the Colombian Golf Federation.

Villegas received an athletic scholarship to attend the University of Florida in Gainesville, Florida, where he played for coach Buddy Alexander's Florida Gators men's golf team in National Collegiate Athletics Association (NCAA) competition from 2001 to 2004. As a freshman in 2001, Villegas was a member of the Gators' 2001 NCAA championship team. During his college golf career, he was the Southeastern Conference (SEC) Freshman of the Year in 2001, the SEC Player of the Year in 2002 and 2004, and an All-American four consecutive years (2001, 2002, 2003, 2004). Villegas graduated from the University of Florida with a bachelor's degree in business administration in 2004.

Paul Alexander Casey (born 21 July 1977) is an English golfer who is a member of the world's top two professional golf tours, the U.S.-based PGA Tour and the European Tour. In 2009 he achieved his highest position, third, in the Official World Golf Rankings.

Casey was born in Cheltenham, but moved with his family to Weybridge, Surrey at the age of six. After attending Cleves School, Weybridge and then Hampton School, he studied A levels at Strode's College, Egham. He then took a golf scholarship at Arizona State University.

His amateur career was distinguished. In the U.S. he was the first man to win three consecutive Pac-10 Championships (1998, 1999 and 2000). In 2000 he broke the championship scoring record held by Tiger Woods (18 under par) with a 23 under par 265. Back on the other side of the Atlantic he won the English Amateur in 1999 and 2000. He was also a member of Great Britain and Ireland's winning 1999 Walker Cup team, where he was only the third player in seventy seven years to record four victories without a single defeat.

Eldrick Tont "Tiger" Woods (born December 30, 1975) is an American professional golfer whose achievements to date rank him among the most successful golfers of all time. Formerly the World No. 1, he is the highest-paid professional athlete in the world, having earned an estimated US$90.5 million from winnings and endorsements in 2010.

Woods turned professional in 1996, and by April 1997 he had already won his first major, the 1997 Masters. He first reached the number one position in the world rankings in June 1997. Through the 2000s, Woods was the dominant force in golf, spending 264 weeks from August 1999 to September 2004 and 281 weeks from June 2005 to October 2010 as world number one. From December 2009 to early April 2010, Woods took leave from professional golf to focus on his marriage after he admitted infidelity. His multiple infidelities were revealed by several different women, through many worldwide media sources. This was followed by a loss of form, and his ranking gradually fell to a low of #58 in November 2011. He snapped a career-long winless streak of 107 weeks when he captured the Chevron World Challenge in December 2011. As of April 8, 2012, he is ranked #8.
