PORTLAND - South Korea 's Kim In-Kyung fired a bogey-free seven under 65 to take a one-stroke lead after the first round of the LPGA Tour's Portland Classic . Kim used a string of four straight birdies on the back nine to record her lowest round of the season by two strokes. "I hit the ball well and made some putts coming down. This is a really good golf course," Kim said. "You have to hit the good shots and also make putts. There's a couple of tricky pins, but I was able to manage." Americans Jennifer Song and Amelia Lewis are tied for second place at six-under. Anna Nordqvist, who has two victories this season, shot a five-under 67. She was joined in fourth place by Laura Diaz, Paraguay's Julieta Granada, Mina Harigae, Alison Walshe, Emma Jandel and Paula Reto of South Africa.–AFP
