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.

The 31-year-old Austrian won the American Express at PGA West without carding a bogey until the 70th hole of the tournament.

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.
