PGA Tour news: Justin Suh and Chris Kirk make major moves at Honda Classic

Suh ensured he will take a one-shot lead over Kirk after birdying the final hole for a six-under-par round of 64.

That took his total to 10 under par, one ahead of Kirk, who made the day's biggest move with a spectacular 62 - one short of the course record at PGA National.

Ryan Gerard and England's Ben Taylor lie two strokes behind Suh on eight under.

Suh, 25, is a PGA Tour rookie who made the step up this season after topping the points race in last season's Korn Ferry Tour.

"I think we played it pretty conservative, but aggressive to our spots. We definitely left ourselves some opportunities, but I thought we just hit it to the right spots on the green," Suh said of he and his caddie's work on Friday.

"We made some long lag putts that fortunately just went in, and that's always a key to some good weeks, so hopefully we just keep it rolling," he added.

Kirk's productive day started with an eagle on the par-five third after a superb 247-yard approach to the green.

The 37-year-old added four birdies during a blistering back nine as the course record looked in reach, but parred his way home from the 16th to settle for a 62.

"It was a bummer not to make it. I felt like I deserved the birdie at 18 after hitting such a great wedge, but I misread the putt. I definitely won't let that put a damper on a really good day," he said.

"It was definitely conditions that lent themselves to being able to be a little bit more aggressive, being able to dial in, kind of carry distances and stuff like that with irons and wedges better," added Kirk, who is chasing his fifth PGA Tour win.

"Usually we're playing for 15, 20 plus yards of hurt going into the wind shots ... but today there was hardly a breath most of the round and so it became a little bit more target practice."
