He dropped six shots over the next three holes, including two balls in Rae's Creek on the 12th hole for a quadruple bogey, and wound up three shots behind Danny Willet.
As the Masters looms, Spieth has been fielding more questions about that collapse on the back nine.
"No matter what happens at this year's Masters, whether I can grab the jacket or I miss the cut or I finish 30th, it will be nice having the Masters go by," Spieth said Monday night during the draw for the Dell Technologies Match Play.

Spieth has never finished worse than second in the Masters in his three appearances.
