Brandt Snedeker shot a four-under par 66 in the third round of the Sony Open In Hawaii on Saturday and will go into the final round tied for the lead with Zac Blair.
Each completed the third round without making a bogey and are one ahead of Kevin Kisner.
"I've had a really tough time with the speed [of the greens[ this week for some reason, because they look extremely fast and they're not rolling out quite yet," Snedeker, who had a one-stroke lead going into the round, said. "They don't have that quite get-away-from-you kind of speed."
Blair and Kevin Kisner shot scores of 64 and 66, respectively, and were tied with Snedeker for much of the afternoon.
Vijay Singh, a co-leader after the first round and seeking to become the oldest PGA Tour victor, shot a three-over par 73 and dropped out of contention.
Matt Kuchar had the low score of the day with an eight-under par 62 that included six consecutive birdies to finish his round. Kuchar trails the leaders by five.
Si Woo Kim, meanwhile, is two strokes back, while Fabian Gomez is four behind and Jason Dufner and Webb Simpson five back.
