PORTLAND, Ore. (AP) Defending champion Brooke Henderson continued her mastery of Columbia Edgewater Country Club, shooting a 70 Saturday to take a two-stroke lead after three rounds of the Cambia Portland Classic.

The 18-year-old Canadian, who claimed her first LPGA Tour win a year ago in Portland, was at 13-under 203 heading into Sunday's final round. Henderson leads Colombia's Mariajo Uribe, who is 11-under after a 71.

Henderson, who three weeks ago won the Women's PGA Championship, has shared or held the outright Portland lead the past six rounds. Henderson is aiming to become the first back-to-back Portland winner since Annika Sorenstam in 2002-03.

Uribe is looking for her first LPGA Tour win. In her sixth year on tour, Uribe's best finish is a third at the 2015 Manulife Classic.
