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.
