Thomas Pieters fired a 68 to join Sergio Garcia at the top of the leaderboard after day two of the Masters Tournament.
Garcia had followed up his opening 71 with a 69 earlier in the day before the big-hitting Belgian once again showed that he was having no trouble learning the ropes on his Augusta National debut.
Pieters had led by four shots on Thursday as he raced out to five under after ten holes but he came home in 40 and when he dropped a shot on the first on day two, he was one over par.
The 25 year old then produced three birdies and an eagle to get back to four under and join Garcia and American duo Rickie Fowler and Charley Hoffman at the summit.
Garcia is searching for a first Major Championship at the 74th attempt and while he has 22 top tens, only three of those have come at Augusta National.
But with the course playing as difficult as it has for many years due to high winds, the Spaniard looked right at home, making six birdies and three bogeys.
Fowler produced the round of the day with a 67 while Hoffman gave some ground back to the field as he could only follow his brilliant opening 65 with a 75.
It is a special course and a special tournament but it is just golf - Thomas Pieters
William McGirt was at two under after a 73, a shot ahead of Jon Rahm, Justin Rose, Fred Couples and Ryan Moore.
World Number Two Rory McIlroy was one over after a 73 alongside Dane Søren Kjeldsen.
After his opening bogey, Pieters put his tee-shot on the sixth to three feet, holed a 25-footer on the ninth and then hit a stunning second into the 13th to set up an eagle.
He made another birdie on the next and after missing makeable birdie putts on the 15th, 16th and 17th, did well to save par on the last.
The three-time European Tour winner claimed four points on his Ryder Cup debut in the autumn and is hoping that experience will stand him in good stead over the weekend.
"I played mostly the same golf and gave myself a lot of chances," he said.
"I don't over-think stuff, sometimes I think people try to over-think it at Augusta maybe and make it so special. It is a special course and a special tournament but it is just golf.
"It's new but I've been pretty calm all week and I'm going to take the experience I got from the Ryder Cup, that's an immense pressure and this will be some pressure as well but I like it and I can't wait for it."
Garcia got off to a blistering start, putting his approach to the first to 12 feet, leaving a short chip into the green after two on the par five second and holing a 22-footer on the third.
If we can put the cherry on top, that would be even better - Sergio Garcia
He missed the green to drop a shot on the par three fourth but put his approach to the ninth to seven feet before bogeys on the tenth and 13th saw him slip back. An excellent second to the par five 15th and approach to the penultimate hole then saw him back in a share.
"Being a part of a Major, it's exciting already," he said. "Having a chance is the best thing and winning it, I'm sure, it's amazing. But for me, I feel so fortunate that I've been able to be healthy, that I've been able to play so many Majors in a row and give myself a lot of chances to win them.
"That for me is already a win, and then, you know, if we can put the cherry on top, that would be even better."
Spaniard Rahm overcame a double-bogey on the tenth with birdies on the second, eighth, 11th and 13th while Englishman Rose signed for a level par 72.
Former champions Phil Mickelson, Adam Scott and Jordan Speith were at level par, a shot ahead of McIlroy and Kjeldsen.
