BETHLEHEM, Pa. — There's no denying this is the biggest week in women's golf — full of good news and bad.

The game's top-ranked player, a former champion and a developmental tour qualifier are one stroke behind a talented second-year LPGA player at the U.S. Women's Open, on a course that doesn't yield birdies easily.

All the while, controversy is swirling around the women's tour amid reports Thursday that LPGA commissioner Carolyn Bivens could be out of her job as early as next week after a faction of key players signed a letter calling for her resignation.

Despite the theatrics, it has the makings of a developing drama on the golf course as well, with the game's top players off to hot starts and a 14-year-old amateur trying to make her first cut in her third Open.

Leader Na Yeon Choi birdied her first three holes, and four of her first five, making the tough Saucon Valley Country Club course look tame with an opening round 3-under 68.

"I know it's a difficult course, but I was really excited to start my round and I thought it was going to be a very, very interesting week for me," the South Korean said through an interpreter.

It could get quite interesting considering the players chasing the 21-year-old.

No. 1-ranked Lorena Ochoa, 2007 champion Cristie Kerr and qualifier Jean Reynolds opened with 2-under 69s, and Hee Young Park, also of South Korea, was another stroke back after a 70.

"Patience is the No. 1 thing you have to have this week," Ochoa said.

But major news about the LPGA and its players keeps intruding on the championship. Just as Choi was completing her round, Golf Digest and Golfweek Magazine, citing sources, reported on their Web sites that Bivens' four-year tenure with the tour is coming to an end.

The move comes after a call for her resignation by key players, who wrote to the LPGA board asking Bivens to step down.

Easily overlooked in the fallout of the LPGA brouhaha were solid rounds by Choi, the runner-up for rookie of the year in 2008, Ochoa, who is seeking her first Women's Open title, and Kerr, aiming for her second championship crown.

Birdies were tough to come by for nearly everyone but Choi, who has won four times in international events. Playing in her second Open, she made Saucon Valley's narrow fairways seem wide and handled its speedy, undulating greens. Choi relied on accurate approach shots throughout and reached 5-under by her 12th hole, before backing up just a bit. Starting on the back nine, she had consecutive bogeys on the 409-yard, par-4 fifth, and 559-yard, par-5 sixth before closing with three pars.

PGA TOUR: At Silvis, Ill., Lee Janzen stirred some memories and was tied with Darron Stiles for the lead after firing a 7-under 64 in the first round of the John Deere Classic.

Janzen has not won on the PGA Tour since he captured his second U.S. Open in 1998, yet he's in position after an impressive start at TPC Deere Run. The 44-year-old was 8 under after birdies on the 16th and 17th holes and played bogey-free golf until the 18th, when he hit a bunker and missed an 8-foot par putt. He was off the course by the time Stiles sunk a seven-foot putt for birdie on the same hole to forge the tie.

Kenny Perry opened with a 68. U.S. Open champion Lucas Glover shot 69.
