The world's top three players Jordan Spieth, Jason Day and Rory McIlroy have continued their unbeaten starts to the World Golf Championship-Dell Match Play by claiming wins on day two.
The trio, who all achieved victories on day one, top their respective groups ahead of the knockout rounds at the weekend.
McIlroy, who is the defending champion, was tested by Smylie Kaufman, but he managed to come from behind twice to claim a 3&1 win.
Spieth started strongly against Victor Dubuisson and grabbed a 5&4 victory, which means that he will take on Justin Thomas for a place in the knockout spots.
Day, who has recently been struggling with a back injury, impressed on the first hole with an eagle and went on to beat Thongchai Jaidee 5&3.
The Australian is guaranteed at least a playoff place as he is one point ahead of the field in Group 2.
