Warning shots from Jordan Spieth at WGC-Dell Match Play in Austin

World No 1 Jordan Spieth crushed Victor Dubuisson five and four to put one foot into the last 16 of the WGC-Dell Match Play in Austin.

The Texan was not quite at his best, but he won easily in the end against the erratic Frenchman and now needs just a half against former college and junior golf pal Justin Thomas today to guarantee himself a playoff, at worst, if Jamie Donaldson wins.

Thomas was eliminated when he lost for the second time, falling two up to Jamie Donaldson at Austin Country Club.
