Tiger Woods described his dramatic birdie on the 16th green as a vital factor in his fourth Masters victory. His 25ft chip from the back of the green turned 90 degrees, rolled to the lip of the hole and finally dropped in.
The birdie gave Woods a two-shot lead but he allowed Chris DiMarco to force a play-off after bogeys at 17 and 18. Woods, who dedicated his triumph to his absent father Earl, who is being treated for cancer, said: "I would rank that as one of the best I've ever hit."
The shot will go down as one of the most memorable moments in Masters history, from Gene Sarazen's double eagle four-wood in 1935 to Larry Mize's chip-in to beat Greg Norman in a play-off in 1987.
"I was just trying to throw the ball up there on the hill and let it feed down there and hopefully have a makeable putt," said Woods, who won at the first play-off hole. "All of a sudden, it looked really good, and it looked like how could it not go in, and how did it not go in, and all of a sudden it went in."
