Yani Tseng shot her third straight 4-under-par 68 on Saturday, and will take a four-stroke lead into the final round of the Women's British Open.
The 21-year-old star from Taiwan took advantage of the short, 472-yard, par-5 final hole by hitting an 8-iron within 20 feet with her second shot. She rolled in the eagle putt to finish off her round, doubling her cushion over Australian Katherine Hull.
"I played really well again," said Tseng, who is at 12 under and has just one bogey through 54 holes. "I really enjoyed the big crowd out there. They clap on every shot and I showed them my big smile all the way around."
Hull played a flawless third round, including five straight birdies to finish with a 66.
"A great way to finish," Hull said. "I'll always remember this round."
The Australian made only one birdie on the way out, at the long sixth, when she hit a pitching wedge within 3 feet. Four straight pars on the back nine followed, before a 5-iron within 6 feet on the short 14th started her run of birdies.
She followed with a gap wedge within 12 feet for birdie at No. 15, and a 5-iron to 20 feet on the following hole. She got up and down out of a bunker at 17, then two-putted from the back of the green for another birdie on 18.
"I really love links golf. I just wish we played more," Hull said. "I played pretty well all day and got a hot putter at the end.
"It will be exciting going out in the final pairing in a major for the first time (today). It's what we all work hard for. It's my first time being in this position but I'm going to treat it like any other day and just go out there and do my best."
South Korean In-Kyung Kim moved into third place at 6 under with a 68. She picked up three birdies on the front side, dropped a shot at the 10th and got it back at the 16th. Her roller-coaster round included another bogey at No. 17, but an eagle at 18 left her smiling.
Birdies at the last two holes moved Brittany Lincicome of Seminole into fourth place at 5 under. Five players were another stroke back.
Earlier, Morgan Pressel equaled the course record with a 7-under 65 to move to 3 under for the tournament.
