EAST CORNING -- Electronic scoreboards may shortchange the LPGA Corning Classic's leader a syllable-and-change, but the rookie's game has lacked nothing through 36 holes -- the last 34 bogey-free.

Virada Nirapathpongporn's 5-birdie round of 67 left her an 11-under-par 133 total and one-stroke lead over Brandie Burton and 18-hole co-leader Nancy Scranton heading into what promises to be a suspenseful weekend of golf.

On Friday, that player was 18-year-old Morgan Pressel, who sprang into contention with a professional-best 64 to snatch a share of 14th position.

Scoreboard space permits no more than "NIRAPATHPO" by way of identifying the leader, a 24-year-old native of Thailand and Duke University graduate who turned professional in June 2004 after building an overstuffed amateur resume.

"It's a place on the LPGA I haven't been," Nirapathpongporn (pronounced neer-uh-PATH-pong-porn) said of her perch, "but every other level of my golf career, I have."

She capped Friday's three-birdie front side with an 8-iron to 8 feet at the ninth, nearly holed her 8-iron for eagle at the 10th and tapped in for birdie, and made it 11-under for the tourney by wedging to seven feet and converting at the 17th. She signed her scorecard following a 14-for-14 showing in fairways hit.

Before this week, she'd cracked 70 in a single round this season, during which her best finish has been a tie for 12th at the Ginn Clubs & Resorts Open, which closed April 30 in Reunion, Fla. That marked her return to the tour after a break prompted by an eye injury sustained March 31 when a rubber band broke free from an exercise device and struck her below the eye.

"I just have to go out, believe in myself and believe in all the work that I've done," Nirapathpongporn said of her weekend voyage into uncharted territory.

Burton, whose five wins include two major championships, has been a stranger of late to weekend contention. Not since 2004 has she posted a top-10, but rounds of 66 and 68 have done wonders for her outlook.

"It's fun again," she said after a five-birdie, one-bogey day. "I feel good. I didn't feel nervous out there at all. I know the weekend might be a little different because I haven't been in this situation for awhile."

Scranton, 45 and a three-time winner, finished stylishly by rolling in a 30-foot putt to close out a 69. Playing the back nine first, she was even for the day through 11 holes but made three birdies on the way in.

"I finished swinging at it much better than I did early in the round, that's always a good thing," said Scranton, whose most recent victory came in 2000.

Round of the Day -- by a full three shots -- belonged to quick-study Pressel, who throttled back the swing a hair and came through with a 64 in her second competitive round at Corning Country Club. The score made for a 10-stroke overnight improvement for a young woman who teed it up for Round 2 six days after her high school graduation.

"(Thursday) night, I worked on the driving range and just realized I was swinging too hard at it," Pressel said. "I went back to what I've always tried to work on, which is tempo and balance. I tried to swing a little easier today and I was firing at the pins, so that makes a difference."

First to the clubhouse with a 9-under 135 total was Vicki Goetze-Ackerman, who arrived at Corning 0-for-2006 in cuts survived. She backed up Thursday's 67 with a bogey-free 68, giving her a grand total of three sub-70 rounds this season.

Starting on the back, her first of four birdies came with a 9-iron to 6 feet at the par-3 15th, and the last came via 8-iron approach to a foot at the par-4 eighth.

"I shot 68 in Phoenix and proceeded to miss the cut," Goetze-Ackerman said, "I kind of expected I wouldn't do that, at least. ... There haven't been a lot of great things that have happened this year. I've been picking through to get them all to feel all right about myself."

Goetze-Ackerman, who shared second place in the 2004 Corning Classic, put the clubs away for a bit last summer in the months leading to the Sept. 15 arrival of son Jacob Aiden Ackerman and returned to the tour in February.

"I thought my patience with my golf would be a lot higher after having the baby," she said. "But my theory is that I have so much patience with Jake that I lose it on the golf course."

Liselotte Neumann was a toe-stub of a bogey at the finishing hole from posting 9-under. She'd made four birdies and nary a bogey to that juncture, but a wayward drive was the root of the lost shot. She picked up a shot on the par-5 second and fifth holes, each with 5-iron in hand for her second shot, on her way to 69.

An 8-under total at the midway point was where 2001 Corning Classic runner-up Mhairi McKay was headed until she, too, slipped up at the 18th. There, she needed a third putt when interminable inspection of the first and short-range second proved unsuccessful.

Natalie Gulbis' bid for a first tour title lost steam after she made birdies on three of her first eight holes to pull to 7-under. Bogeys at the 14th and 15th and pars the rest of the way gave her a 71 and a share of 19th, six off the lead.
