The following year, Woods won his third consecutive U.S. Junior Amateur Championship; he remains the event's only three-time winner. In 1994, at the TPC at Sawgrass in Florida, he became the youngest winner of the U.S. Amateur Championship, a record he held until 2008 when it was broken by Danny Lee. He was a member of the American team at the 1994 Eisenhower Trophy World Amateur Golf Team Championships (winning), and the 1995 Walker Cup (losing).
Woods turned pro at age 20 in August 1996 and immediately signed advertising deals with Nike, Inc. and Titleist that ranked as the most lucrative endorsement contracts in golf history at that time. Woods was named Sports Illustrated's 1996 Sportsman of the Year and PGA Tour Rookie of the Year. On April 13, 1997, he won his first major, the Masters, in record-breaking fashion and became the tournament's youngest winner at age 21. Two months later, he set the record for the fastest ascent to No. 1 in the Official World Golf Rankings. After a lackluster 1998, Woods finished the 1999 season with eight wins, including the PGA Championship, a feat not achieved since Johnny Miller did it in 1974.
Earned his 80th PGA TOUR victory and first since 2013, winning the TOUR Championship for the third time in his career to move within two of Sam Snead's TOUR-best 82 victories. Finished the season No. 2 in the FedExCup, with runner-up finishes at the Valspar Championship and PGA Championship among his seven top-10s. Led the TOUR in Strokes Gained: Approach the Green (0.938) for the sixth consecutive season in which he played the minimum number of rounds. After originally being selected as a Captain's Assistant for the United States Ryder Cup team, was later selected as a captain's pick and played in the event for the eighth time.
