LPGA Tour rookie Mao Saigo birdied six of her first nine holes on Thursday for a 9-under 63 and a one-stroke lead after the first round of the Maybank Championship. Haeran Ryu of South Korea was a stroke behind while two others were tied for third, two strokes behind the Japanese player at the Kuala Lumpur Golf and Country Club. “I made a lot of middle-length putts so that’s why I played so well,” Saigo said.
