BETHESDA, Md. (AP) — In Gee Chun breezed to an 8-under 64 and jumped out to a record-tying five-stroke lead in the first round of the Women’s PGA Championship. Most of the field slogged through the day on the wet Blue Course at Congressional. But Chun birdied seven of eight holes during one stretch. Pornanong Phatlum and Hye-Jin Choi each shot 69, and no one else broke 70. Chun’s lead is tied for the biggest ever after the first round of a women’s major. Mickey Wright led this tournament by five after the first round in 1961. Chun is a two-time major champion, most recently at the Evian Championship in 2016.
