Billy Davis hasn’t yet achieved the golf success of his twin sister, Anna, but that could change very soon. While Anna Davis has won the 2022 Augusta National Women’s Amateur and competed in multiple major championships, including the last two U.S. Women’s Opens, Billy still is searching for a breakthrough of his own. The 17-year-old from Spring Valley, Calif., just might get that this week at Daniel Island Club after advancing to the semifinals of the 75th U.S. Junior Amateur on Friday morning with a convincing 6-and-4 win over hometown favorite Rowan Sullivan, of Charleston, S.C. Billy, who has committed to attend Auburn University with his sister next year, has been taking a lot of advice from his well-known sibling, especially the way she carries herself on the golf course in big moments. “One thing that I like is … how she walks,” said Billy, who played alongside his sister for the West Team in the recent Wyndham Cup. “She walks like she’s leading a golf tournament every time, even when she’s not winning. It’s one thing that I can take away from her for sure.” Anna lost in the Round of 16 to Gianna Clemente in her U.S. Girls’ Junior debut last week in Colorado at the U.S. Air Force Academy Eisenhower Golf Club. Billy has already one-upped her in his U.S. Junior Amateur debut. Now he’d like to take home the large silver trophy to display in their Southern California home.
