Aldrich Potgieter has the lead going into the final round of the Mexico Open, minus the cushion he enjoyed after a sloppy finish Saturday that made him settle for a 4-under 67 and a one-shot advantage over Brian Campbell at Vidanta Vallarta.

Potgieter, the 20-year-old power player from South Africa, started with a four-shot lead and held off one challenge early from Stephan Jaeger, who closed within one shot after six holes.

The next challenge came from Campbell, who at times was 50 yards shorter off the tee than Potgieter but made up for it with his putter, including a 60-foot birdie on the par-3 ninth.

Potgieter was leading by three shots with two holes left in the third round when he badly missed his tee shot to the right on the par-3 17th, the ball settling in some bushes. He managed to punch that out into the grass, then hit a beautiful pitch to save bogey.

On the par-5 18th, Potgieter came up well short with a 7-iron for his second shot after another big drive. From a waste area, he went just over the back of the green, chipped to a front pin and had to make a 5-footer for par.

Campbell finished with a birdie for a 64 to get within one shot as both go for their first PGA Tour title and a trip to the Masters.

Jaeger went from within one shot to falling five shots behind, only to rally with a pair of birdies on the par 5s for a 66 to finish three behind.

Potgieter was at 20-under 193.

Alex Smalley had a 64 and was five shots behind, with Aaron Rai (68) and Ben Griffin (67) another shot back.

Justin Hastings of the Cayman Islands, the San Diego State senior who won the Latin American Amateur last month to earn a trip to the Masters, had a 65 and was tied for ninth with Patrick Rodgers and Nicolai Hojgaard, who twice chipped in for eagle on the back nine.

LPGA Tour

Angel Yin birdied three of her final four holes on the front nine to help set up an 8-under 64 to take a five-stroke lead into the final round of the LPGA Thailand tournament.

The Monterey Park native and Arcadia High alum had a three-round total of 21-under 195 at Siam Country Club’s Pattaya Old Course.

Sponsor invite Akie Iwai of Japan, who led after the first two rounds, shot 71 and dropped into second place. She stumbled with her first bogey of the tournament on the ninth hole.

The event is the first stop of the LPGA’s so-called Asian swing before the tour moves to Singapore and China over the next two weeks.

The 26-year-old Yin’s best finish in four previous appearances at LPGA Thailand was a share of third place in 2021.

“Off the tee, I wasn’t hitting it as well as the last two days, but I got away with some good lies and managed to capitalize on my opportunities,” said the No. 17-ranked Yin, who is chasing her second LPGA title after winning the Buick LPGA Shanghai in 2023.

Local stars Moriya Jutanugarn and Jeeno Thitikul each posted a 69 to sit at 201, a stroke behind Iwai.
