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.

I think that was the biggest challenge today was keeping aggressive on my targets,” Straka said after his two-under 70. “Nerves, just complete nerves. Stomach in a knot, the whole nine. So, yeah, just really excited about the way I handed the pressure today.

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