AUGUSTA, Ga. — Shane Lowry electrified Augusta National, sending tremors through the course from the roars after he had a hole-in-one on the par-3 sixth hole.

 Lowry, playing with good friend and Ryder Cup teammate Tommy Fleetwood, celebrated madly when the ball bounced onto the green, trundled toward the hole and disappeared into the cup.

 It got him to 8-under par for the tournament and only four shots behind leader Rory McIlroy at the time.

As Lowry celebrated and the huge crowd went crazy, Harris English, who was on the 16th green, which is just about 80 yards from the sixth green, looked up the hill at Lowry and playfully bowed.

 It was only the seventh ace on the sixth hole in the Masters’ 90-year history.

Jon Rahm, who made the cut on the number on Friday, shot a 1-over-par 73 on Saturday and is 5-over for the week.

 “I came in with the same expectations I come into any other major, any other tournament — not any higher or lower,’’ he said. 

Asked why he’s struggled, he said, “If I knew the why … [I’m] probably not going to say it right now, and I would have tried to avoid it if I knew the why I played the way I played so far.’’

He suggested that maybe he’s forcing things, being so far behind the lead.

 “The only thing about a weekend like today, once things are not going well enough, is you can start trying things just to see how it feels or how you can do it in competition,’’ he said. “[That’s] a bit of what I did today [and] probably what I’ll do tomorrow. Hitting it on the range is one thing; doing it on the golf course is a different thing.’’

Adam Scott, for one, has delighted in the firm and fast conditions the course has been in thanks to no rain this week.

 “The firmer and faster they can get it, the better,’’ said Scott who is at even-par through three rounds. “I love seeing the fairways play firmer.’’

Aldrich Potgieter, who missed the cut in his first Masters, marveled at the game of 60-year-old José María Olazábal, a two-time winner, with whom he was paired the first two days.

 “He’s got one of the best short games that I’ve played with,’’ Potgieter said. “Even at the age of 60, it’s incredible. I think that’s kind of why this sport is so good and how it’s special. I mean, he played great. He had some unfortunate breaks today that kind of put him back a little bit, but watching him play it was really special.’’ The long-hitting South African called his first Masters experience invaluable.

 “These weeks are huge,’’ he said. “There’s a level of experience this week. You’ve got to know this golf course inside and out, and I think that just plays a big advantage into the week as well. These moments are really big, and we’ve got to learn to kind of put ourselves in those big moments.’’
