Kaori Yamamoto of Japan leads the U.S. Senior Women’s Open by five strokes heading into the final round, with a total score of 7-under 206 after shooting a 1-over 72 on Saturday. The tournament, held at Fox Chapel Golf Club in Pittsburgh, experienced a three-hour rain delay. Yamamoto's consistent performance, including notable shots on the 12th hole, has kept her ahead of Hall of Famers Annika Sorenstam, Juli Inkster, and others tied for second at 2-under. Sorenstam, the 2021 champion, expressed satisfaction with her game despite the challenging conditions. JoAnne Carner, 85, missed the weekend cut but has impressively shot her age or lower multiple times in the tournament’s history. This marks Yamamoto's first tournament in the United States, and her journey from caddying for a friend last year to leading this year underscores her remarkable progress.
