World number one Scottie Scheffler shot an eight-under-par 64 to move to within two shots of leader and US Ryder Cup team-mate Ben Griffin in the third round of the Procore Championship.

Griffin retained the lead with a steady 70 to end the day on 16 under, one shot ahead of US amateur Jackson Koivun at the Silverado Country Club in Napa, California.

Koivun, a 20-year-old Auburn University student, moved into outright second with a 68.

Scheffler stormed from 14th overnight into third with 10 birdies – five on the front nine and five on the back.

He was denied a share of the lead only after a chip into a bunker on the par-four 14th led to a double bogey.

Scheffler shot 70 in the first round, which ended his run of 21 successive sub-70 scores, and 68 in the second.

“There’s definitely some tricks to this golf course, things you’ve got to get used to,” he said.

“There are things that are hard to notice in the practice rounds. But when you start playing under tournament conditions you start seeing a little of those nuances.”

US Open champion JJ Spaun and Russell Henley are best placed of the remaining eight Ryder Cup players on nine under.
