So much has changed for Brooke Henderson since she last played in a U.S. Women’s Open at Lancaster Country Club.

Henderson was playing in Monday qualifiers and earning sponsor exemptions for LPGA Tour events back in 2015 after her request for an age waiver to compete at Q School in late 2014 was denied. Then just 17 years old, she qualified for the 2015 U.S. Women’s Open based on her score at the previous year’s event, which she had earned her way into through a qualifying event as an amateur.
