The rules violation, which sees the Mexican’s score adjusted from a 73 to a three-over-par 75, came at the par-five 15th and leaves him in a tie for 52nd place, 10 strokes behind leader Justin Rose.

"After Mr. Ancer had signed his scorecard and exited the scoring area, video evidence was reviewed by the Committee regarding a potential breach of Rule 12.2b(1), which states that touching sand in a bunker right behind the ball results in a penalty," Augusta National said.

"The touching of the sand was deemed visible to the naked eye. Had this not been the case, the video evidence would have been disregarded and a penalty would not have been applied."

Ancer, playing in his second Masters, said he had been informed the penalty was for "unintentionally grazing the sand" with his backswing.

I was just informed that I have been assessed a 2 stroke penalty for unintentionally grazing the sand in my backswing on hole 15. While I’m gutted, I can’t wait to get after it tomorrow. pic.twitter.com/5ZOlthQzeE
