Austin Cook fired an eight-under 64 to grab the lead at the CareerBuilder Challenge as Jon Rahm continues to lurk in California.

Cook, a one-time winner on the PGA Tour, moved into a one-shot lead after his fine third round Saturday.

The American carded his 64 on the La Quinta Country Club course to push into 19 under.

Cook is one shot clear of countrymen Andrew Landry (70) and Martin Piller (67).

World number three Rahm is still in contention in a tie for fourth after the Spaniard shot a two-under 70 on the PGA West Stadium Course.

The 23-year-old struggled late in his round, making bogeys on three of his final six holes.

Scott Piercy (66) is alongside Rahm at 17 under.

In what is sure to be a thrilling final round, another five players are within four shots of the lead.

Adam Hadwin (67), Grayson Murray (67) and Brandon Harkins (68) are at 16 under, while Jason Kokrak (71) and Seamus Power (65) are a shot further back.
