Defending a U.S. Open title is a rare feat. Only seven women have ever successfully defended in the history of the event.

BEDMINSTER, N.J. — Brittany Lang, the defending champ at the U.S. Women’s Open, said she walked down the fairways at Trump National Bedminster during her practice rounds, hearing fans call out to her, “Let’s do it again, Brittany!” Of course, the supportive sentiment was much appreciated. But what fans probably don’t realize is how difficult a feat a U.S. Women’s Open defense actually is. A statistical breakdown shows that more defending champs have missed the cut (eight) than successfully defended their title (seven).
Don’t tell Brittany Lang, but it’s really, really hard to defend a U.S. Women’s Open title
