(CNN) -- American Anthony Kim shot a six-under 64 to share the lead with Colombia's Camilo Villegas after the second round of the PGA Honda Classic at the Palm Beach course in Florida.
Kim collected seven birdies and reach the halfway stage on eight under while Villegas got round in 66 for the second day in a row.
Fiji's Vijay Singh is a stroke behind the pair after he also shot 66 with American veteran Jerry Kelly another stroke off the pace while Canada's Mike Weir, Australian Nathan Green and Northern Ireland's Graeme McDowell are among the chasing pack.
Kim, 24, revealed that he has started to reap the benefits of recent practice and hopes it signals the beginning of a purple patch on the course.
"I feel really good. I've been working hard on my game, and the last couple of months I've really started to play better," Kim told the PGA Tour Website.
"I haven't put four good rounds together so I'm happy to have another opportunity to put four good ones together and hopefully have a chance to win the tournament.
"I haven't even been thinking about what I'm going to shoot. I didn't have a goal, a number in mind, but just to go out there and hit some quality golf shots.
"It's been a long time since I've been able to have confidence and fire at some flags and be able to be aggressive and feel comfortable in that situation.
"So I'm really happy with how I'm playing. It's just a matter of time before I put four good ones together and start winning some golf tournaments again."
Rhys Davies heads into the final round of the Malaysian Open level with Thailand's Kiradech Aphibarnrat at the top of the leaderboard.
The 24-year-old from Wales is 11-under par after a third round of 71 while Aphibarnrat shot 68 to take a share of the lead in Kuala Lumpur.
Kiradech's compatriot Thongchai Jaidee (69), Soren Hansen of Denmark (69) and Koreans K.J. Choi (69) and Noh Seung-yul (67) are all a shot behind.
Kiradech brilliantly birdied three of his last four holes while Davies' round included three birdies against a double bogey but the Welshman is keen to make amends on the final day.
"It's good pressure. If I shoot the best score on Sunday then I win. That's a good thing," Davies told the tournament's official Website.
"There are a number of great players up there so it is up to me to worry about my own game and try not to worry about them. If I score lower than them then I will come out on top."
