CARNOUSTIE, Scotland (AP) - Caroline Masson of Germany shot a 4-under 68 to double her lead to two strokes after the third round at the Women's British Open on Saturday.

The 22-year-old Masson made three birdies in the front nine and three on the back to hold off a late charge from Yani Tseng. The top-ranked Taiwenese player closed within a shot at one point after picking up five strokes in as many holes, including an eagle.

Masson has totaled 15-under 201.

Catriona Matthew of Scotland leads the home challenge, but she is six shots off the pace after hitting a 68. Inbee Park of South Korea is also at 207 for a share of third place.
