Bryson DeChambeau leads by one from Scottie Scheffler after the first round of the Masters was completed on Friday.
The LIV golfer finished seven under par but world number one Scheffler showed ominous touch in his bogey-free 66.
Max Homa and Nicolai Hojgaard were among 27 players finishing their rounds on Friday and both are at five under, while Tiger Woods hit a one-over 73.
England’s 2016 winner Danny Willett, playing his first tournament since September, is four under par.
The performance of Willett, given his struggles with injury surprised even himself. The 36-year-old underwent shoulder surgery in late September and was expected to be out for at least 12 months but has returned within six.
“I was still unsure on Monday if I was going to play or not,” Willett, who holed a 20-foot birdie putt on the 18th to move within three of the lead, told Sky Sports.
“I’ve been sat at home watching guys play golf on TV for six months. It’s good to be back.”
Rory McIlroy hit a 71 and defending champion Jon Rahm a one-over 73.
