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 two further back.
Rory McIlroy hit a 71 and defending champion Jon Rahm is at one over, while five-time champion Tiger Woods was one of 27 players unable to finish.
American Woods looked in good form at one under par when darkness fell. 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.
