(born Dec. 30, 1975, Cypress, Calif., U.S.) U.S. golfer. The child of a Thai mother and an African American father, Woods was a golf prodigy and won the first of three consecutive U.S. Junior Amateur Championships (1991–93) when he was 15 years old. In 1994 at age 18 he became the youngest winner of the U.S. Amateur competition, which he also won in 1995 and 1996. In 1997 Woods at age 21 became the youngest player and the first of African or Asian descent ever to win the Masters Tournament, winning by a record margin of 12 strokes. Winner of five other PGA tournaments in 1997, Woods became the youngest player ever ranked first in world golf competition. On July 23, 2000, Woods became the fifth player—after Gene Sarazen, Jack Nicklaus, Ben Hogan, and Gary Player—in golf history, and the youngest, to achieve a career grand slam of the four major championships (the Masters, U.S. Open, British Open, and PGA Championship). In 2005 he completed his second career grand slam.
