Ryan Fox has made a strong debut at the Masters.
The New Zealander carded an opening round two under par 70 to be in a tie of 17th, five shots off the pace.
Fox, who teed off early on Friday morning (NZ time), shot four birdies, two back to back on the 12th and 13th holes, and two bogeys.
He finished with a birdie on the 18th and is now in a solid position to make the cut at Augusta.
LIV Golf's Brooks Koepka, a four-time major winner, used a closing birdie to move into a three-way share of the clubhouse lead with Jon Rahm and Viktor Hovland.
Koepka, one of 17 LIV Golf players left in the field after Kevin Na withdrew midway through his round, shot a seven-under-par 65 in ideal scoring conditions to join Spain's world number three Rahm and Norway's Hovland in the lead.
American Cameron Young was two shots off the lead while world number seven American Xander Schauffele and former majors champions, Irishman Shane Lowry, Australia's Adam Scott and American Gary Woodland were all a further shot back.
The only blemish on the scorecard for Koepka, who won last week's LIV Golf event in Orlando, was a bogey at the par-five 13th but the four-time major winner birdied 15 and 17 before draining an eight-foot birdie at the last.
Hovland, who stood out as much for his play as the bold floral pattern on his shirt, fired his lowest score in a major while Rahm caught fire after a four-putt, double-bogey at the first hole.
Hovland made his move early as he rolled in a 25-foot eagle putt at the par-five second and added three birdies across a four-hole span from the sixth to reach the turn at five under.
Playing in a group with Tiger Woods and Schauffele, Hovland made a sensational par save at the 10th after an errant approach left him with a tough chip without much green to work with and then padded his lead with a 37-foot birdie at the 11th.
Hovland picked up another birdie at the new-look par-five 13th, and then capped his day with a string of pars for his first sub-70 round at Augusta National.
"I don't care how good you hit it out here, you have to chip the ball. You have to have a short game," said Hovland.
"And especially on that back nine when I hit a lot of bad shots, to be honest, but I managed to keep myself in it by hitting some really nice chips and making some really nice putts."
Rahm overcame his shaky with a pair of birdies on the second and third holes and never looked back.
The Spaniard then charged up the leaderboard when he followed a birdie at the seventh with an eagle at the eighth where he stuffed his approach shot to four feet before capping his round with the fourth of his back-nine birdies.
Woods, who has never missed a cut at Augusta National as a professional, teed off having played one event this year and the rust showed as he rarely gave himself any opportunities and admitted to feeling sore after a 74 that was his worst Masters start 2004.
The five-time champion salvaged his round with two late birdies but closed with a bogey after an unfortunate break off the tee that forced him to take an awkward stance on his approach with his right foot in the sand and the other in the grass.
"I felt like I drove it good. I just didn't do the job I need to do to get the ball close," said Woods. "Today was the opportune time to get the ball -- get the round under par, and I didn't do that today."
Tournament favourite Scheffler, bidding to become the fourth player to repeat as Masters champion, carded a four under par 68 to be tied for sixth.
