In a way, Moore's routine this week was both familiar and unfamiliar. Moore had played the course a handful of times before competing this week, and the rental digs help simulate a normal tournament situation. It's her first Airbnb experience, though, and she hopes to get home at some point during the week to see friends.

“I've traveled a lot for most of my tournaments, so I'm used to staying in a hotel more often than staying at home,” Moore said. “I felt just staying somewhere else than at home helps me a lot, too.”

Moore is about to enter her third season at the University of Arizona. The 18-year-old graduated a year early to kick-start that experience, and with a positive result. She was second in the stroke-play portion of the NCAA Women’s Championship in 2016.

Next week, Moore’s brother Tyler will play the U.S. Amateur at Riviera Country Club in Pacific Palisades, Calif., which is only a few hours from Escondido. This week, however, it’s all about Haley. Her Monday cheering contingent included members from her home country club, her high school golf coach, and perhaps most notably, Craig Davis, a University of Arizona alumnus who Moore says “is like an eight-time club champion” at San Diego Country Club.

“It's really cool to have family and friends out here supporting me because it's probably the first time in a while that they get to see me because I'm in college now,” Moore said. “To see them out here is very special, and they're cheering me on whether I play good or play bad.”

As for Gillman, who will enter her sophomore season at the University of Alabama this fall, this Women’s Amateur has a special feel because her face is posted around the venue on various pieces of championship signage. Gillman says playing this championship never gets old.
