The 11-year-old Li shot rounds of 74-68 on the par-72 Old Course on Monday. She will surpass Lexi Thompson as the youngest qualifier in the U.S. Women's Open, which is June 19-22 at Pinehurst No. 2. Thompson was 12 in the 2007 Open.
Beverly Klass played the 1967 Open when she was 10. There was no qualifying.
Li, of Redwood Shores, California, already has a big win on her resume. She captured the girls 10-11 division at the inaugural Drive, Chip and Putt contest at Augusta that preceded the Masters this year. She beat second-place qualifier Kathleen Scavo by seven strokes at Half Moon Bay.
