CARNOUSTIE, Scotland -- Caroline Masson bogeyed her final hole on Saturday, but still has a two-stroke lead after the third round of the Women's British Open.
Masson, the relatively unheralded German, posted a four-under 68 and finished 54 holes at 15-under 201.
That's an incredible score for three rounds at Carnoustie, which, once again, played easy on Saturday thanks to little wind, bright skies and a shortened track.
It's a wonderful story having a player like Masson, who is playing only her second LPGA Tour event and hasn't won on her home circuit, the Ladies European Tour, so far under par at such a spectacular venue and in such a storied event.
But standing in Masson's way to this fairy-tale finish is the defending champion, who also happens to be the No. 1 player in the world.
Yani Tseng shot a six-under 66 on Saturday and moved into second place at 13- under 203. At the ripe age of 22, Tseng won her fourth major title this year at the LPGA Championship.
Former Women's British Open champion Catriona Matthew posted a four-under 68 on Saturday and is tied for third place with 2008 U.S. Women's Open champion Inbee Park, who shot a one-over 73 in the third round, at nine-under 207.
They're all going to be chasing Masson, the second-round leader who looked a little nervous to start Saturday's third round.
She hit a terrible tee shot at the first and made bogey. Masson quickly got herself together and rolled in a six-foot birdie putt at the second to get back to 11-under par.
At the fifth, Masson drained a 20-footer for birdie, then tapped in a short birdie putt at the par-five sixth. The German was 13-under for the championship and five strokes clear of the field.
Masson sank a six-foot birdie putt at the 11th. Now at 14-under par, Masson was in command, but Tseng made a huge charge after the turn.
The defending champion holed a six-foot birdie putt at 10 and followed with another birdie at 11. Tseng knocked her tee ball to three feet at the par- three 13th and was 10-under par for the tournament.
Tseng kept the momentum going with a 50-foot eagle putt at the par-five 14th. That long eagle effort got Tseng within two of Masson's lead, but Masson birdied the same hole a few groups later to extend her advantage to three shots.
Tseng reached the next par five, the 17th, in two shots and two-putted for birdie from 35 feet. She was back down two, but once again, Masson responded. She narrowly missed her eagle putt at 17, but kicked in a short one for another birdie.
Masson was 16-under par and three ahead of Tseng, who parred the last.
Masson found sand at the last and made a bogey. That trimmed her third-round lead to two strokes and she'll be in the final group on Sunday against the best player in the world.
Brittany Lang (69), Sophie Gustafson (70) and Se Ri Pak (73) are tied for sixth place at seven-under 209.
Paula Creamer (71), Sun Young Yoo (69), Anna Nordqvist (69), Mika Miyazato (72) and Dewi Claire Schreefel (74) are knotted in ninth place at six-under 210.
NOTES: In two seasons on the Ladies European Tour, Masson's best finish is a share of second place earlier this year...Tseng can become the first player to successfully defend her title at this event since Sherri Steinhauer in 1998-99.
