Tiger Woods closes his amateur career by winning one of golf's most dramatic matches. The 20-year-old Stanford student becomes the first individual to win three consecutive US Amateur titles with 16 holes to go and a five-hole disadvantage. It is also the first time that any player has won three straight US Amateurs after being down five holes or more in any round. Woods began the final day with a one-shot lead over David Gass, who had gone into the final day at Oakland Hills Golf Club in suburban Detroit trailing by two shots. But then Gass made four bogeys on the 544-yard 18th hole and Woods closed out the victory with a 4-under 67 to finish at 13-under 277. "I'm just so happy I could cry," said Woods, who earned $150,000 for each of his victories. "It's amazing; it's really a dream come true." Golf's ruling body, the United States Golf Association, named Woods as the winner before he even reached the 18th tee. "We are pleased to see him go into tomorrow's final round with a comfortable lead," USGA president Fred Ridley said in a statement. "He's been great all week long and we're very proud of him."
