Curtis Cup teenager Sally Watson produced a birdie at the first extra hole to win a play-off for the Under-18 girls' title in the Red Tail Open, at Red Tail Golf Club near Boston, Massachusetts on Sunday.

Sally, a 17-year-old resident student at the David Leadbetter/IMG Golf Academy at Bradenton, Florida, had rounds of 68 and 71 to tie at five-under-par 139 with Dottie Ardina (71-68) from Laguna in the Philippines.

Over the two rounds, Sally had one eagle and seven birdies. Her eighth birdie came at the 37th hole - just when she needed it most.

A second Scot in the field, Gemma Dryburgh from Aberdeen, finished a creditable joint seventh in the international field with scores of 77 and 73 for 150. After birdieing the second, fourth and fifth in her second round, Gemma had a run of bogeys at the eighth, 11th, 12th and 13th.
