PORTLAND, Ore. — I.K. Kim birdied the first four holes on the back nine Thursday and finished with a 7-under 65 to take the first-round lead in the Portland Classic.

The South Korean player birdied seven of the first 13 holes and closed her afternoon round with five straight pars. She won the last of her three LPGA Tour titles in 2010.

Kim, the winner of a Ladies European Tour event in England in July, tied for 42nd last week in the Canadian Women’s Open.
