SOUTHAMPTON, N.Y. -- Inbee Park couldn't see her final tee shot past about 150 yards.
Nothing fazes the world's top-ranked player these days, though. Fog had rolled in off Great Peconic Bay, and the horn sounded with Park's group on the 18th fairway. The threesome finished out the second round of the U.S. Women's Open, with Park calmly sinking a birdie putt from 12 feet to move closer to history.
She shot a 4-under 68 on Friday for a 9-under total to lead fellow South Korean I.K. Kim by two strokes. Park is seeking to win the year's first three major championships; no one has accomplished that feat in a season with at least four majors.
Of the players yet to finish the round, the closest, England's Jodi Ewart Shadoff, was five strokes back with three holes to go.
Ha-Neul Kim, the first-round leader, had a 77 to fall to 1 under.
Maude-Aimee LeBlanc of Sherbrooke, Que., followed her opening round 69 with a 77, and is at 2-over 146. Brooke Mackenzie Henderson of Smiths Falls, Ont., shot a 76, and is at 147. Charlottetown's Lorie Kane, Stephanie Sherlock of Barrie, Ont., Jessica Sheply of Owen Sound, Ont., Kirby Dreher of Fort St. John, B.C., and Isabelle Beisiegel off St. Hilarie, Que., missed the cut. Nicole Zhang of Calgary did not complete her round.
Players were surprised Thursday to arrive at Sebonack to find the tees moved up and the weather calm -- an easy course by U.S. Women's Open standards. On Friday, the setup and the conditions were more what they expected: The wind picked up and some pins were tucked into uncomfortable spots.
Then the mist settled in late in the afternoon session.
Of the 114 players who finished, only nine were under par for the round.
