Munoz shoots second 60 of the PGA season

Sebastian Munoz has shot a 12-under par 60 in the opening round of the Byron Nelson to become the first player in PGA Tour history with two rounds of 60 or better in the same season.

Munoz was at two-under par when he earned a one-stroke penalty because of a wayward tee shot at the eighth hole.

The 29-year-old Colombian, who lives in the Dallas area, then went six-under over the next four holes. He made eagles at the two par 5 holes, the ninth and the 12th, and sank three-foot birdies in between.

In the middle of the fairway after his tee shot at the 18th hole – another par 5 – Munoz missed the green to the right. But he made a nice flop shot and sank the round-ending 12-foot birdie.

Munoz also had a 60 in the opening round of the the RSM Classic at Seaside in Georgia in November, although that was a 10-under score. He went on to finish third there.

TPC Craig Ranch, the second-year home of the Nelson, is about 30 miles north of downtown Dallas and 30 miles east of the University of North Texas, where Munoz went to school.

He finished his round before two major winners from Dallas teed off in the afternoon in the same group, with a four-stroke lead over Mito Pereira and Peter Malnati among the earlier finishers.

Masters champion Scottie Scheffler, the No.1 player in the world, was making his first individual start since winning the Masters five weeks ago.

Three-time major winner Jordan Spieth, ranked No.9, was in action for the first time since his win at RBC Heritage the week after the Masters.
