She was thinking about something bigger.
The rising junior at Lakeside High School edged Megan Sabol by one shot with 8-over-par 80 to win the girls 14-18 division in the Solvay Specialty Polymers AJGT Tournament at Bartram Trail.
When Drew Belt and Carlos Santos started the Papa John's Augusta Junior Golf Tour this year, they envisioned it as a springboard for local players to reach out to bigger tours and events.
It was apt for Yi on Monday, who after the tournament traveled to Atlanta for today's U.S. Girls' Junior Championship qualifier. If she qualifies, she'll be part of the field for the July 18-23 event at Olympia Fields Country Club near Chicago.
Before leaving, she took a detour to the practice green.
"I hit it really good today. My ball-striking was great," Yi said. "But my putting was terrible."
Yi made it 4-for-4 in winning each AJGT event she has played this summer. The 10-event series culminates in the Aug. 3-4 Tour Championship at Jones Creek Golf Club.
Yi has also earned two victories on the regional Hurricane Junior Golf Tour.
Yi was joined in the winner's circle Monday by David Hemann, whose even-par round of 72 earned him a three-shot victory over Rodney Wendt, of Evans, in the boys 15-18 division.
It is Hemann's third victory in a row. He also won last week's Georgia State Golf Association event at Bartram Trail and the AJGT event at Jones Creek.
"It feels good," said the rising junior at Greenbrier High School, who pointed to accurate iron play and a switch to a Scotty Cameron putter for his success. "It's finally coming around. I've been working at it hard for a while, and it finally came together."
Other division winners included Zach McLain, of Gilbert, S.C. (2-under 70 to win in 13-14 boys); Patrick Jean-Pierre, of Augusta (5-over 41 to win in 11-12 boys); Owen Sanders, of Evans (1-over 37 from the William Bartram Junior Tees to win in boys 9-under); and Madison Harwell, of Evans (7-over 43 to win in girls 10-13).
