PORTLAND, Ore. — The Cambia Portland Classic has had a little bit of just about everything as the LPGA’s longest-running non-major, but in its 45-year history hasn’t seen a teenage winner quite like Brooke Henderson.

The 18-year-old Canadian became Portland’s first back-to-back champion in 13 years when Henderson shot a final round 1-under 71 to win by four strokes over American Stacy Lewis at Columbia Edgewater Country Club.

The second-ranked Henderson posted a 14-under 274 for 72 holes, though it was a far different grind than her performance in 2015, when she won the Portland Classic by a record-setting eight strokes.
