Sebastian Munoz fires 60 to open Byron Nelson

Sebastian Munoz did that 60 thing again.

Munoz topped the leaderboard at the Byron Nelson Classic with an opening-round 60 on Thursday, becoming the first player in PGA Tour history with multiple rounds of 60 or lower in the same season.

“It’s a great feeling when everything is clicking,” Munoz said after draining his ninth birdie of the first round in McKinney, Texas.

The University of North Texas product made few mistakes with a 12-under round at TPC Craig Ranch, opening a four-shot lead over Mito Pereira of Chile and American Peter Malnati through the morning wave.

Needing his third eagle of the day on No. 18 for a 59, Munoz went wide of the green on his approach but was able to get an up-and-down birdie to seal the 60.

Munoz bogeyed the par-4 eighth but sandwiched two birdies between eagles on No. 9 — with a 15 1/2-foot putt — and No. 12 and recorded a 28 on the back nine. Munoz eagled 9 and 12 in the first round of the event in 2021.

The 29-year-old Colombian also scored a 60 in the first round of the RSM Classic in November on a par-70 course.
