By the time Brooke Henderson made only her second bogey of the tournament on the 13th hole on Sunday, it was really too late to do any damage in her quest for her first LPGA Tour win and the first for Canada in over 14 years at the Cambia Portland Classic.
At that point, she was still eight up on the rest of the field and she would add her fifth birdie of the day on 17 and add another bogey on 18 to finish with a three-under 69.
After tying the 54-hole record on Saturday, Henderson set a tournament 72-hole record at 21 under.
The victory, which should cement full-time status on the LPGA Tour for the 17-year-old from Smiths Falls, Ont., makes her only the third player in LPGA history to win before her 18th birthday, which is next month, joining Lydia Ko and Lexi Thompson.
She is also only the second player in LPGA history to win after Monday qualifying.
Hamilton’s Alena Sharp tied for 10th at 10 under after firing a final round, one-under 71 on Sunday on four birdies and three bogeys.
SooBin Kim, who lives in Coquitlam, B.C., also shot a 71 on Sunday to finish one shot behind Sharp and tie for 13th.
The final leaderboard is here.
