YANGMEI, October 21, 2011 (AFP) - The duo, who are on seven-under, hold a two-stroke advantage over world number one Tseng and fellow Taiwanese Candie Kung.
Spaniard Munoz played flawless golf to shoot the lowest round of the tournament with a six-under-par 66. She recorded one eagle and four bogeys on her round, but knows there is room for improvement heading into the weekend.
"I shot much better than yesterday, but I actually didn't play that much better," said Munoz. "I just had a really slow start yesterday, I was three-over through five and then I played pretty good after that."
Swede Nordqvist, who is looking to notch a first LPGA Tour victory since 1999, carded five birdies and one bogey en route to a 68.
"The most important thing is to keep the ball in play and try to hit fairways and try to hit greens," said Nordqvist, who has won twice on the LPGA Tour.
"I hit a lot of greens today, so I think that's one of the keys on this course, especially with the wind out here."
While all eyes in Yangmei might have been on Tseng, Kung has caused the focus to slightly shift after a stellar four-under-par 68.
Kung, who is a nine-year veteran on the LPGA Tour, notched five birdies and one bogey to stand two strokes behind the leaders.
She said she had no problem with Tseng grabbing all the headlines.
"She got herself all the attention from her good play," said Kung. "I'm more like a big sister to her. She's a good friend of mine and I'm very happy for her that she actually got to that No. 1 spot and is able to keep it there."
Fans have flocked to see crowd-pleaser Tseng in action, but she was off-colour, carding a 71.
"This is the first time in my life I see so many people on the golf course and like all over the fairways and tee and green," said Tseng. "It was really exciting and so much fun to play under the crowd."
