Match Play: Spieth, Day and McIlroy earn second wins

The top three ranked players continue to win in Match Play

Jason Day, who exhibited apparent back pain on the last hole of Wednesday's round at the WGC-Dell Match Play, showed no signs of lingering pain during Thursday's group play at Austin Country Club in Texas.

Day, coming off a victory in the Arnold Palmer Invitational, defeated Thongchai Jaidee of Thailand, 5 and 3, and is now 2-0 heading into the final round of group play. Day's round featured six birdies and an eagle after driving the green on the opening hole, a par 4.

"It's not too bad," he said of his back issues. "Yesterday it was definitely sore. I mean, I've had it before. I know what the protocols are for me when these things pop up. It's a disc. When it gets inflamed the facet joints lock up and then everything goes into spasm and I can't move and it's really difficult to play golf."

Jordan Spieth, the No. 1 ranked player, continued his run of dominance with a 5 and 4 win over France's Victor Dubuisson. Spieth is now 2-0 in group play heading into Friday's match against his good friend Justin Thomas.

Rory McIlroy, after winning because of a shank from Thorbjorn Olsen on the 18th hole on Wednesday, bounced back to defeat Smylie Kaufman, 3 and 1, to move to 2-0.

Phil Mickelson edged Daniel Berger, 1 up, while fellow group member Patrick Reed defeated Matthew Fitzpatrick, 4 and 3. Mickelson and Reed are each 2-0 and will play each other on Friday to see who advances to the weekend.

Rickie Fowler halved his match with Scott Piercy, moving to 0-1-1 and needing several things to go right on Friday to advance.

The easiest match of the day went to Zach Johnson who beat Martin Kaymer, 8 and 6.
