LOS ANGELES, May 20, 2014 (AFP) - Li, of Redwood City, California, earned her spot in the tournament by firing rounds of 74 and 68 at a sectional qualifying tournament.
The previous record for the youngest player in the event was Alexis Thompson who competed at 12 years, 4 months, 18 days in 2007.
In 2013, Li took part in the US Women's Amateur Public Links Championship where she missed the cut.
The 2014 US Women's Open will run from June 19-22 at Pinehurst Resort in Pinehurst, North Carolina.
