MENLO PARK, Calif. — Kim Hyo-joo played the first six holes in 6 under before stalling Saturday at tree-lined Sharon Heights, leaving her with a five-stroke lead over Nelly Korda with a round left in the Fortinet Founders Cup. Kim, the 30-year-old South Korean player ranked eighth in the world, shot a 6-under 66 to get to 17-under 199. She won the tournament in 2015 in Phoenix for the second of her seven LPGA Tour titles. “I’ve been in the lead, so I want to finish tomorrow well,” Kim said. Four shots ahead entering the day, she had four birdies and an eagle on the par-5 fifth in the opening burst that ended with a bogey on the par-5 seventh. “The start up to hole 6, I believe, was unbelievable golf and I can’t even believe it,” Kim said. “I had a lot of birdies and eagle, too. But I did also have some bogeys I shouldn’t have done. The start felt like almost a game.” Kim opened the back nine birdie-bogey-bogey-birdie, then birdied the par-4 16th to get back to 17 under. She left a 15-foot birdie try a foot short on the par-3 17th and parred the par-5 18th after driving
