It's liftoff for captain Kirk in PGA Tour's Classic

Of the 7,200 rounds played at the Honda Classic since it moved to PGA National 17 years ago, only two of those - one belonging to Australian Matt Jones - were better than Chris Kirk's on Friday.

Kirk shot an 8-under 62 in the second round, moving him to 9 under for the week and one shot behind Justin Suh (64) at the tournament's midway point.

He had an eagle and six birdies, hit 16 greens and took full advantage of a rare windless morning at PGA National.

"Usually we're playing for 15, 20-plus yards of hurt going into the wind shots, and 15, 20 yards of help on downwind shots," Kirk said.

"It's really difficult to get those just right when it's really windy. But today there was hardly a breath most of the round, and so it became a little bit more target practice."

Suh had four consecutive birdies on holes 8 through 11, rolling in putts from 5, 15, 25 and 30 feet in that span, to post a 36-hole total of 10-under 130.

"I think we've been trending in the right direction," Suh said. "Every week I've been improving and just certain spots, and I think it's gratifying just to see the progressive work pay off."

There was no shortage of players taking dead aim. Ryan Gerard (63) and Ben Taylor (65) were tied for third at 8 under. Ben Martin (64), Eric Cole (66) and Brice Garnett (64) were all another shot back.

Shane Lowry shot his second consecutive 68, highlighted by a 57-foot birdie putt on the par-3 17th - his ball staying on-line even after rolling over another player's coin on its way to the hole.

Australians Min Woo Lee (69), Cameron Percy (68) and Harryson Endycott (65) are all tied 22nd at 3 under for the tournament.

Endycott improved on his opening round by seven shots, with six birdies and a lone bogey.

Geoff Ogilvy had a disappointing Friday to slip down the field. His 68 was followed by a 73, as he fell right on the projected one-over cut line.

Compatriot Brett Drewitt, however, faces a few anxious hours.

The Sydneysider was still a hole shy when play was suspended and at one over, can't afford any slip ups on the last.
