The 14-year-old Thompson also won the title in 2007. She led after every round this week, and opened a 12-stroke lead on Friday, one shy of the tournament record. Her 5-under-par final round left her only one stroke behind Debbie Hall for biggest winning margin ' a 13-stroke victory in 1977.
I never gave up, and I didnt take anything for granted, said Thompson. I just wanted to make more and more birdies.
Sarah Brown played with Thompson in the final group and finished second for the second straight year.
Vogel shot a 66 in the final round to beat Jordan Spieth by two strokes. He had four consecutive birdies from the eighth to the 11th holes, putting him in control. Vogel will head to Southern California in the fall.
I wanted to win my last tournament before going to college, and I accomplished that goal, Vogel said. I could not picture this any other way, leaving junior golf.
