KAWAGOE, Japan -- Lexi Thompson had to bring in a team manager the last three holes when her caddie succumbed to the heat. Players walked down sunbaked fairways using umbrellas, some of them occasionally holding a bag of ice on their heads.
Madelene Sagstrom had a hot start of her own Wednesday in women's golf.
With a tough pitch to 4 feet for par on the final hole, the Swede kept bogeys off her card on a day of searing heat for a 5-under 66, giving her a one-shot lead over top-ranked Nelly Korda of the United States and Aditi Ashok of India.
