Na birdied his first full hole when he resumed a rain-delayed first round Friday morning, and went on to finish at 7-under 63 and share the first-round lead with Anthony Kim at the Crowne Plaza Invitational at Colonial.
When play was suspended Thursday afternoon, Na was on the ninth green at 4-under. He started Friday by making a 3-footer to save par, then hit his approach shot inside 5 feet at the tenth and made birdie.
'I'm very pleased with my round. I got off to a really good start and was able to clean up my par at nine,' Na said during a 30-minute break before starting his second round. 'I birdied 10 and it kind of snowballed from there.'
Ted Purdy, Jeff Maggert, Ben Curtis and Arron Oberholser were a stroke back at 6-under.
Frank Lickliter, who played in the same group as Na, joined Jim Furyk in a group of six players at 5-under. The others were Nathan Green, Jeff Quinney, Peter Lonard and Tim Clark.
Lickliter, who had six birdies and a bogey in eight completed holes Thursday, made a 13-foot birdie putt to begin Friday and get to 6-under. He had the lead alone at 8-under before a double bogey at the par-4 15th, where he went into the trees and didn't get on the green until his fourth shot.
'I hit the wrong spot,' Lickliter said.
Na and Lickliter were among 57 players -- half of the 114-player field -- who had to finish their first rounds Friday morning. With light rain falling, the second round began before everybody had completed their first round.
With more rain in the forecast Friday afternoon and the last group not scheduled to tee off until 4:59 p.m. local time, the second round won't be completed before nightfall.
Kim finished his round Thursday with birdies on the last six holes -- the longest birdie streak on Tour this season -- for his best-scoring round since turning pro late last year.
The flurry of birdies came after a bogey at the 417-yard 12th, when he missed the fairway, came up short of the green on his approach and pushed his par save past the hole. That led to a self-scolding session walking to the 13th tee.
'I gave myself quite a talking to, probably stuff I shouldn't be saying,' Kim said.
Kim hit his tee shot at the 171-yard 13th inside 4 feet and his birdie putt at the next was even shorter before weather suspended play. After a delay of 1 hour, 22 minutes, Kim finished his round with four more birdies -- all ranging from 9 to 17 feet.
'There really wasn't one thing. Usually when something turns around during a round you can tell. I don't know what it was,' he said. 'Maybe it was taking the head cover off finally and putting it, or opening my eyes. Something changed, and I don't really know what it was.'
While the PGA Tour rookie looked within, Purdy was inspired by an 'American Idol.'
Two days after casting at least 100 votes for Jordin Sparks, the teenage daughter of one of his golfing buddies, Purdy overcome an opening three-putt bogey in a round of 64 before play was suspended for good Thursday.
'Her family is just a real positive family. I'm trying to bring that to my golf game,' Purdy said. 'She inspired me (Thursday). ... I know her dad real well.'
Sparks' father is retired NFL player Phillippi Sparks, a board member with Purdy at the same Phoenix country club.
After bogeying the 407-yard 10th, Purdy recovered with five birdies in a seven-hole stretch. He got to 7-under before a bogey on his 16th hole, the 432-yard seventh.
Brian Gay made a hole-in-one Friday at the 194-yard eighth hole with a 7-iron. ... There have been 13 players this season with five straight birdies. ... Patrick Sheehan's 62 in 2005 is the best opening round at Colonial.
