Henderson wins Portland Classic

Brooke Henderson’s stock shot up even further on Sunday as she cruised to victory at the Cambia Portland Classic by a tournament-record eight strokes after recording a tournament-record 21-under-par 267.

Thailand’s Pornanong Phatlum, South Korea’s Ha Na Jang and Candie Kung of Chinese Taipei finished in a tie for second after finishing on 13-under, while defending champion Austin Ernst, Mo Martin and Azahara Munoz ended nine strokes adrift of Henderson.

Meanwhile, world number two Lydia Ko fired a two-under-par 70 on Sunday to finish in a tie for 46th.

Henderson, who carded a three-under-par 69 on Sunday, began her round with a bogey-free front nine that included birdies at the fifth, seventh and ninth.

Her strong run continued into the back nine and she made another birdie at the 12th before faltering at the next hole, where she registered her first bogey of the round. The 17-year-old proceeded to make her fifth birdie at the 17th before stumbling at the 18th, which was the scene of her second bogey.

Despite her mistake at the last, Henderson went on to become only the third player in LPGA history to win a tour event before turning 18, with Ko and Lexi Thompson the other two players to accomplish the feat.

Neither Phatlum (68), Jang (70), nor Kung (70) could produce the kind of round needed to challenge Henderson, with the trio forced to settle for a share of second.

Ernst, Martin and Munoz registered 12-under-par to finish nine strokes off the lead in a tie for fifth.

Ko meanwhile ended her tournament 17 shots behind Henderson after finishing on four-under-par following a final-round 70.
