AUGUSTA, Ga. (AP) -- Danny Willett in a green jacket was hard to believe considering he wasn't even sure he could play the Masters two weeks ago.
Jordan Spieth was even more stunned.
Nine holes away from history, the defending Masters champion threw it all away in a collapse around Amen Corner that was shocking even by Augusta National standards. He played the opening three holes of the back nine in 6 over par, including a quadruple bogey at the 12th.
Willet, five shots behind with six holes left to play, birdied three of his last six holes to polish off a round that might not get its due because of Spieth's meltdown.
