A six-under-par 65 was three shots off the pace for Louis Oosthuizen on Thursday in the first round of the Shriners Hospitals for Children Open on the PGA Tour in Las Vegas.

Oosthuizen made four birdies and an eagle on a blemish-free scorecard, while leader Bryson DeChambeau made nine birdies while also going bogey-free to card a 62 to go with his pro-am 59 the day before. DeChambeau led by one from five players on eight-under.

Oosthuizen was one shot clear of compatriot Charl Schwartzel who made five birdies on a day and a course conducive to scoring. Dylan Frittelli made just a single bogey in his four-under, while MJ Daffue – based in the US – made three bogeys on his way to a 70. Former South African Rory Sabbatini joined Frittelli on four-under.

DeChambeau had no fewer than five occasions when he had putts for eagle – all three par-fives and two par-fours. He hit 11 of 14 fairways and 16 of 18 greens while needing just 29 putts. He gained over two shots on the field on the greens and almost three shots off the tee.

Oosthuizen averaged over 329 yards off the tee in an impressive performance, but DeChambeau was out over 352 yards.
