Bryson DeChambeau leads by one from Scottie Scheffler after a storm-shortened first day at the Masters.
The LIV golfer finished seven under par but world number one Scheffler showed ominous touch in his bogey-free 66.
England’s 2016 winner Danny Willett, playing his first tournament since September 2023, is four under par.
Rory McIlroy hit a 71 and defending champion Jon Rahm a one-over 73, while Tiger Woods was one of 27 players whose rounds were curtailed by darkness.
The five-time winner looked in good form at one under par when the hooter sounded to end play. However, having only played 25 holes in a single tournament so far this year, the 48-year-old will have to play 23 on Friday alone to complete rounds one and two.
Play will resume at 07:50 local time (12:50 BST) with the second round beginning at 08:00.
Woods, who said earlier this week he “aches every day” after suffering a catalogue of injuries in recent years, said he expects to have “between 20 and 30 minutes in between rounds”.
“It’ll be a natural flow from the finish of the first round and [into] the second. The body is OK,” he added.
