(Reuters) - Canadian teenager Brooke Henderson birdied four of her final seven holes to grab the lead after the second round of the LPGA Tour's Cambia Portland Classic in Oregon on Friday.
After starting on the back nine, the 17-year-old overcame a slow start where she bogeyed her second hole to come home with a five-under par 67 for an 11-under, 36-hole total.
She has a one stroke lead over German Caroline Masson, who enjoyed the best round of the day, a bogey-free eight-under 64, at the Columbia Edgewater Country Club.
