There are a few big names giving chase, but the tournament is Straka's to lose in the desert. The final round is underway, and Golfweek will bring you live updates, highlights and more throughout the afternoon.

Sepp Straka shot an 8-under 64 on Saturday while his top competitors failed to match his sizzling pace, staking the Austrian to a four-shot lead over Charley Hoffman, Jason Day and Justin Lower after three rounds at The American Express.

Straka made a bogey on the par-5 16th hole Sunday, his first of the week in the desert, and then added a bogey on the par-4 18th. All that kept him from reaching the tournament scoring record set by Nick Dunlap last year.
