Mexico Open Round 2: Aldrich Potgieter Ties the Course Record and Bolts Four Clear

Friday at Vidanta Vallarta belonged to a 20-year-old who swings like the fairways owe him money. Aldrich Potgieter shot a 10-under 61, matched the course record and turned a crowded leaderboard into a chase.

Potgieter sits at 16-under 126 after 36 holes of the Mexico Open at VidantaWorld, four shots clear of Stephan Jaeger (64) and Brian Campbell (65) at 12 under. Aaron Rai, the highest-ranked player in the field, shot 64 to get to 11 under. Ben Griffin, Akshay Bhatia and Isaiah Salinda are tied at 10 under. All three of Thursday's co-leaders went backward: Jeremy Paul (70) is at 8 under, Kris Ventura (71) at 7 under and Harry Hall (72) at 6 under.

Ten Under, and It Could Have Been More

The scary part about Potgieter's 61 is how much it left on the table. He did not birdie two of the shorter par 5s on the back nine, and that ended any real thought of breaking 60, a number he has already posted once on the Korn Ferry Tour.

The round also needed a bit of rescue work. At the 10th, Potgieter's tee shot found the water, and instead of a scorecard wound he chipped in from about 20 feet for par. Outside of that, he holed seven putts from 10 feet or longer, according to the AP. Combine that with the driving and you get a number nobody else in the field could touch.

He nearly finished with a flourish. At the par-5 18th his approach found a bunker, the escape came up short, and he two-putted from 25 feet for par. "But it was OK," Potgieter said of the closing par, per the AP. "I knew I made a lot of extra birdies throughout the day where that wasn't going to hurt me."

The Driver Is the Story

Let's talk about the length, because it is the headline. Seven of Potgieter's drives went 325 yards or longer on Friday. At the 661-yard par-5 12th, he reached the green in two and left himself about 20 feet, on a hole most of the field treats as a three-shot par 5.

Vidanta Vallarta gives big hitters room to swing, and Potgieter is taking full advantage. "I love the golf course. It definitely suits my game, I think, in a lot of aspects," Potgieter said.

The résumé backs it up. Potgieter won the Amateur Championship at 17, became the youngest winner in Korn Ferry Tour history at 19 last year, and according to Field Level Media he is now the fourth-youngest player to shoot 61 or better in a PGA TOUR event, behind only Patrick Cantlay, Nick Dunlap and Tom Kim.

Jaeger and Campbell Keep Pace

Jaeger's 64 came with a hiccup and a heater. The German's only bogey arrived at that same 12th, where a wedge flew the green. The response was six birdies over the final 10 holes, including a 26-footer, to climb into a share of second.

"It's one of those golf courses I feel like if you hit it nicely and you give yourself a lot of chances," Jaeger said, per the AP.

Campbell was quieter, which seems to be the style. A second straight 65, finished off with a birdie on the last hole, has Campbell tied with Jaeger at 12 under. Two rounds, two 65s, and a place near the front of the line.

Rai, the world No. 29, matched Jaeger's 64, and the Englishman is five back. Griffin (65), Bhatia (66) and Salinda (67) form the next wave six back.

Cut Day Drama

The cut fell at 3 under, and 77 players made it, per the AP. Antoine Rozner had a chance to move the line with a birdie on the final hole, which would have sent 12 more players home, but ended up needing a 10-foot par just to stick around. Defending champion Jake Knapp shot 72 and made it right on the number.

Two Masters-bound amateurs are playing the weekend. Justin Hastings of the Cayman Islands, the Latin America Amateur champion, birdied three of the last four holes for a 67 and sits at 6 under. U.S. Amateur champion Jose Luis Ballester shot 69. Blades Brown, the 17-year-old who turned pro this year, also shot 69 and made the cut, 11 shots off the lead.

Not everybody made it. K.H. Lee, Charley Hoffman and Kurt Kitayama all missed, and so did Padraig Harrington, per Field Level Media.

The Weekend Question

A four-shot lead at the halfway mark is a big cushion, but it is not a trophy, and the guy holding it has never closed out a PGA TOUR event. Jaeger has already won on TOUR. Campbell has been steady as a metronome. Rai has the world ranking. Behind them is a pack that can make birdies in bunches on a course with five par 5s.

What we know after Friday: Potgieter has the power, the lead and a course that fits like a glove. Saturday will show whether the rest of the field can make the young South African sweat.
