Bryson DeChambeau reeled off five birdies in six holes on the back nine Thursday to hold off late-charging world number one Scottie Scheffler for a one-stroke lead at the darkness-halted 88th Masters.

DeChambeau, the 2020 US Open winner, fired a seven-under-par 65 for his lowest major round in relation to par while 2022 Masters winner Scheffler made four birdies in five holes on the back nine at Augusta National.

Denmark's Nikolai Hojgaard, among 20 first-time Masters starters trying to become the first rookie winner since 1979, birdied his way through "Amen Corner" – the course's famed 11th, 12th and 13th holes.

The Dane was two back on 5-under with three holes remaining when play was stopped for darkness after rain delayed Thursday's start by two and one-half hours.

In all, 27 players, including 15-time major winner Tiger Woods, must finish the first round Friday morning. They include American Max Homa, 4-under through 13 holes, and England's Tyrrell Hatton, 3-under after 14 holes.

Three adrift in fourth on 68 was England's Danny Willett, the 2016 Masters winner who birdied three of the last four holes.

DeChambeau birdied the first three holes, stumbled with a bogey at nine, then began his birdie binge from 17 feet at the tricky par-3 12th.

Scheffler's 66, his first bogey-free Masters round, included a nine-foot birdie putt at the par-5 second, an 18-foot birdie putt at the par-3 sixth and holing out a 30-foot bunker shot at 12.

Scheffler, trying to match Woods as the only players to win the Masters twice while atop the rankings, closed with two pars.

Woods, returning to major golf after right ankle surgery last April but still struggling to walk, seeks a 24th consecutive Masters cut to break to record he shares with Gary Player and Fred Couples.

He was 1-under after 13 holes.
