Former US Open champion Lucas Glover will take a two-shot lead into the final round of the Zurich Classic of New Orleans.
Glover, one ahead overnight and bidding for his first PGA Tour win since the 2011 Wells Fargo Championship, fired a two-under 70 to move to 14-under-par for the tournament.
He mixed five birdies with three bogeys on Saturday, finishing off with a birdie at the par-five 18th to ensure a two-shot cushion over fellow Americans Billy Horschel, DA Points, Kyle Stanley and Jimmy Walker.
"The wind picked up a little bit more than was forecast," Glover said about the tougher conditions facing the late starters on a mainly overcast afternoon. "There was a bunch of good scores earlier and we knew that.
"I knew there were some birdies there, I just didn't take as much of an advantage as I should have.
"Tee to green is pretty good, although today wasn't as good as the first two days, and my irons were okay. I had a few misreads and my (putting) speed was a little off today. I left a bunch of 10, 12-footers short."
Due to the threat of afternoon thunderstorms forecast for Sunday, tee times for the final round have been brought forward with the start scheduled for 0700 local time, 1300 BST.
Stanley's seven-under 65 was the equal low round of the day, while Horschel and Walker both carded 66s and Points 70. Kevin Stadler is one further back after a 65.
Chinese 14-year-old Tianlang Guan had a difficult day, carding a 77 to drop to the back of the field at two over.
"I just didn't do very good in the morning and was definitely in trouble with my driver," Guan said after mixing three birdies with five bogeys and an ugly triple at the sixth.
"I played pretty good in the middle of the round but still it was not a very good round for me."
