Jordan Spieth, Justin Thomas in Contention at AT&T Byron Nelson

When the final putt dropped on Saturday at the AT&T Byron Nelson, three-time major champion Jordan Spieth’s third round 64 had him traiing University of North Texas’ Sebastian Munoz by one shot heading into the final round.

Munoz got out to a hot start on Thursday when he became the first player in PGA Tour history to shoot two 60s in the same season and his third round 66 was good enough to give him the solo lead going into Sunday where he will be paired with Speith and Joaquin Neimann.

“The first time my dad ever brought me out here I must have been five or six years old and I just remember trying to get an autograph from the pros. I remember Davis Love being so nice to me early on and it was, I mean from then on that kind of solidified my dream to be a professional golfer,” Spieth said. “So having a chance to win this event, this will be kind of the best chance I’ve maybe ever had going into Sunday. So it’s really exciting, a lot of friends and family out, done a good job not putting too much pressure on myself, I just wanted to get into contention and obviously see what needs to be sharpened for next week. But there’s no better prep for a major than winning the week before, I think, so go out there tomorrow and try and do what I did the last couple days.”

Justin Thomas matched Spieth’s 64 to sit in a tie with James Hahn at 18-under, three shots behind Munoz.

“The course is playing very easy, I think it’s very obvious and apparent of that. A lot of tees moved up, a lot of bullpens and the greens are getting a little firmer, which is making it a little more challenging and putting more of a premium on hitting the fairway,” Thomas said. “But you know what you’re getting into when you come here, it’s very open, a lot of short clubs and with the groans rolling this well you know if you’re putting it well you can make it from about anywhere. So you just kind of have to just keep your head down and just keep trying to make birdies.”

Thomas has been staying with Spieth this week at Spieth’s house in Dallas.

“It’s great,” Thomas said. “They’re some of our closest friends, him and Annie, we love hanging out with them and especially now with their baby. And we’re having a great time and it definitely feels like a very relaxed competitive week, if that somehow is a thing.”

Masters champion and world No. 1 Scottie Scheffler is five shots out of the lead following a 7-under 65.

“A few missed opportunities, but 7-under not really putting really good is a pretty good score,” Scheffler said. “I haven’t really seen the ball go in very much, which is frustrating because you got to make putts out here to shoot low scores, and I fought my way kind of back into the tournament but I need a hot putter tomorrow if I want to make some noise.”
