Jessica Korda has fired her caddie midway through the third round of the U.S. Women's Open.

The 20-year-old American replaced Jason Gilroyed with her boyfriend, Johnny DelPrete, after the ninth hole Saturday. Korda says she and Gilroyed had several disagreements and she wasn't in the right frame of mind.

She says she needed to just start having fun, and the switch seemed to work: After shooting 5 over on the front nine, Korda was 1 under the rest of the way. She finished with a 76 and was tied for sixth at 1 over, 11 strokes behind leader Inbee Park.

DelPrete is a professional golfer but had never caddied for Korda before. He'll be back on the bag for Sunday's final round.

Her father, 1998 Australian Open tennis champ Petr Korda, is the caddie for younger daughter Nelly this week.
