Noh leads in New Orleans
Another bogey-free third round saw Noh Seung-yul open up a two-shot lead in the Zurich Classic of New Orleans.
Noh's blemish-free 65 in the third round allowed him to take advantage as overnight leader Ben Martin struggled and carded a 73 that saw him drop into a share of fourth - four shots off the pace.
Noh became the first player to complete 54 holes at TPC Louisiana without a bogey. Three consecutive birdies on the 14th, 15th and 16th holes gave him the lead over Keegan Bradley, who matched Noh's round of 65 to move up to second, two shots back.
Bradley had eight birdies on his round but bogeyed the par-three ninth while Robert Streb was back in third place, his round of 68 leaving him three shots back.
"I'm most proud this week of where I've been mentally on the golf course and how calm I've felt," Bradley said afterwards.
"I love being in this position, a couple back going into Sunday. I'd like to be a couple in the lead, too, but I love chasing."
Martin, who had led through the first two days on the back of a course-record 62 on Thursday, found the going much tougher on Saturday with bogeys on the second and ninth, his sole birdie coming on the seventh hole.
England's Paul Casey had the best round of the day, carding six birdies on the back nine on his way to a 64 which lifted him 20 places to a share of seventh, still five shots off the lead.
