Nelly Korda won a back-nine showdown with Hannah Green of Australia with a par on the 18th hole to capture the Mizuho Americas Open by a stroke for her sixth win in seven starts on the LPGA Tour this year. The victory Sunday made the 25-year-old Korda the first player since Inbee Park (2013) to record six wins in a single season. Korda also bounced back from seeing her record-tying five-tournament winning streak snapped last week by Rose Zhang at the Cognizant Founders Cup. Zhang withdrew Thursday after three holes with an intestinal issue.
