Henderson won the Cambia Portland Classic by eight strokes Sunday to become the third-youngest champion in LPGA Tour history at 17 years 11 months 6 days.
Henderson closed with a three-under-par 69 at Columbia Edgewater in Portland, Ore., to finish at 21-under-par 267, the lowest total since the event went from 54 holes to 72 in 2013.
"I was just trying to keep going low and trying to push it to get even further under par, which I wouldn't have had that a couple months ago," Henderson said.
Henderson earned $195,000 and has made $661,818 in 10 events this year. Last year, LPGA Tour Commissioner Mike Whan denied Henderson's age petition, preventing her from playing Q-school. Because she's assured of finishing in the top 40 in earnings, Henderson will earn a tour card for 2016.

Henderson bogeyed the final hole, only her third dropped stroke of the week, and had 24 birdies. She got into the field Monday with a 68, then shot 66-67-65 to take a five-stroke lead into the final round. Pornanong Phatlum (68), Ha Na Jang (70) and Candie Kung (70) tied for second.
Defending champion Austin Ernst shot a 68 to tie for fifth at 12 under.
Morgan Pressel, second after three rounds, had a 75 to tie for 10th at 10 under.
