On Sunday at iconic Riviera Country Club, World No. 1 Nelly Korda is on a hunt for history. A late birdie run on Saturday has her tied for the lead and 18 holes away from capturing her first U.S. Women’s Open title. If she’s successful, she’ll also accomplish a feat no American woman has in over 60 years. One key to Korda’s recent success, as she explained in her press conference Saturday night, was a “mindset shift” that has her dialed into one of the great runs in golf history.
