Aldrich Potgieter, the PGA Tour’s youngest player and its biggest hitter, had five straight birdies to surge into the third-round lead and finished with a 7-under 65 on Saturday for a two-shot edge.

The 20-year-old tour rookie started the week averaging 326.6 yards off the tee — several yards longer than Rory McIlroy — and will be shooting for his first win on tour Sunday.

Max Greyserman (66), Jake Knapp (66), Mark Hubbard (67), Andrew Putnam (67) and Chris Kirk (69) were two shots back. Three more players were another stroke behind.

Collin Morikawa, the highest-ranked player in the field at No. 5 in the world, shot a 68 to start the final round four shots back. Two years ago in Detroit, he was outlasted by Rickie Fowler in a playoff. Morikawa, a two-time major champion, has not won on the tour since October 2023 at the Zozo Championship in Japan.

He won the British Amateur at the age of 17 and became the youngest Korn Ferry Tour winner last year, paving the way for him to become the second-youngest player to earn a PGA Tour card through the minor league just after his 20th birthday. The youngest was Jason Day, who was 19 in 2007.

Trio tied atop U.S. Senior Open leaderboard

Padraig Harrington chipped in from 20 yards off the green on the 18th hole Saturday to salvage a floundering round and pull back into a tie for the lead with Stewart Cink and Mark Hensby at the U.S. Senior Open.

Harrington’s chip-in for birdie capped a round of 2-under 68 and put him in the same spot he was in to start — tied with the same two opponents he played with over another tricky day at the Broadmoor that included wind, rain, even a flash of lightning that pulled the players off the course for a half-hour.

Hensby’s 68 included another four birdies, along with an eagle, to bring his total to 19 for the tournament.

Cink’s included a third shot on the par-3 16th that came from farther away than the second after a misread on a putt from just off the green curled some 30 feet away from the hole.

They were at 8-under 202. One shot behind the leaders was Thomas Bjorn, whose 66 matched the best round of the day and set up what appears to be a four-man fight for the title.

Team of Schmelzel, Valenzuela lead at Dow

Sarah Schmelzel and Albane Valenzuela took the third-round lead Saturday in the Dow Championship, shooting a 2-under 68 in alternate-shot play to move into position for their first LPGA Tour victories.

Schmelzel and Valenzuela had a 13-under 197 total at Midland Country Cup heading into the better-ball final round. They opened with an alternate-shot 68 on Thursday and had a best-ball 61 on Friday.

The teams of Jin Hee Im-Somi Lee (68) and Manon De Roey-Pauline Roussin-Bouchard (69) were a stroke back.

Jennifer Kupcho and Leona Maguire, the second-round leaders after a 60, birdied the final two holes for a 72 that left them tied for fourth at 11 under with Lauren Hartlage-Brooke Matthews (66) and Sung Hyun Park-Ina Yoon (67) . Kupcho won in 2022 with Lizette Salas.

Lexi Thompson-Meghan Kang (68) and Rio Takeda-Miyu Yamashita (67) were 10 under.

Defending champions Ruoning Yin and Jeeno Thitikul, both among the top five in the women’s world ranking, were 9 under after a 67.
