Webb Simpson has maintained a four-shot lead with 18 holes left to play at the Shriners Open in Las Vegas.
The 28-year-old from North Carolina is still looking for his first win since lifting the US Open last year and took a massive step towards ending that wait by posting 63 to take the lead yesterday.
A solid four-under 67 today sees him leading the way on 19-under-par after three rounds, followed by Chesson Hadley, who signed for the same number, on 15-under.
Jeff Overton (-14) carded 68 to retain slim hopes of capitalising on a possible fourth-round collapse at the top.
Jason Bohn (-13), Ryo Ishikawa (-12), Ryan Moore (-12), Russell Knox (-12), JJ Henry (-12), Sean O'Hair (-12), William McGirt (-12) complete the top 10.
