AT&T Byron Nelson Classic final-round preview: Jordan Spieth and Justin Thomas ready to pounce

So when he closed par-bogey-par-par, his 21-under final score was only good enough for a one-shot lead over Jordan Spieth, who had earlier posted a 64.

Riviera winner Joaquin Niemann fired a second straight 65 to lie two off the pace while Justin Thomas jumped 11 spots to sit three back after a 64

Add in defending champion K.H. Lee on 17-under (four back) and World No.1 Scottie Scheffler (five behind) and Munoz has plenty of potential final-round threats.

He converted the second of them (2019 Sanderson Farms Championship) after a playoff and finished third (2017 Greenbrier Classic) and fourth (2021 John Deere Classic) in the other two.

Stats: Munoz ranks 2nd for Greens In Regulation and 6th for Strokes Gained: Approach so far. He's also 4th for SG: Putting but most of his 5.755 strokes over the field were achieved in that opening 60 (4.270).

Quotes: "Overall my mental game was really good. I got off to a good start and kind of kept pushing."

Munoz lives in Texas and went to college there but knows playing partner Jordan Spieth will get all the attention in round four. "I mean besides winning in Bogota, Colombia, I never been the favourite of any other place. So it's a familiar spot, I mean Jordan is, of course, the golden boy here, so everyone's favourite. I'm good friends with him, so it's going to be a lot of fun tomorrow."

What's more, four of those were in Texas where he had to settle for 2nd, 18th, 8th and 10th despite being roared on by the local galleries. Did he put too much pressure on
