Austin, Texas

Jordan Spieth and Patrick Reed enjoy few things more than trying to beat each other, and that's when they are partners. The stakes are even higher in the Dell Technologies Match Play.

Win or go home.

Spieth and Reed did their part Thursday by winning their matches for a second straight day to set up a showdown on the skirts of Hill Country in Texas. They play Friday to determine who wins the group and advances to the weekend of this World Golf Championship.

Reed fired the first shot when asked what made Spieth a good opponent in match play. "I don't know. My back still hurts from the last Ryder Cup," he said with a laugh, alluding to the way he carried Spieth in their partnership at Hazeltine to a 2-1-1 record in team play during a rare American victory.

Spieth dodged trouble early against Li Haotong to win 4 and 2.

Right behind was Reed, who defeated Charl Schwartzel in a close match.

Defending champion Dustin Johnson lost to Adam Hadwin 4 and 3.

PGA: Tony Romo settled down after a nervous start, only to come undone on the back nine in his PGA Tour debut. The former Dallas quarterback played a four-hole stretch in a 5 over on the back nine that led to a 5-over 77 in the Corales Puntacana Resort and Club Championship. He was 14 shots behind leader Brice Garnett.

LPGA: Laura Davies had a nightmare round, shooting 82 days after contending for a title at age 54, and Caroline Hedwall and Jackie Stoelting, the former Fuccillo Kia Classic winner at Capital Hills in Albany, shot 66 to lead the Kia Classic in Carlsbad, Calif.
