SOUTHAMPTON, N.Y. - Inbee Park led the U.S. Women's Open with the second round suspended by fog.

The top-ranked Park shot a 4-under 68 on Friday for a 9-under total to lead fellow South Korean I.K. Kim by two strokes. The horn sounded with Park on the 18th fairway, and the group finished the hole. She calmly sank a birdie putt from about 12 feet to move closer to history.

Park is seeking to win the year's first three majors; no one has accomplished that feat in a season with at least four. 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 back to 1 under.

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 tougher. Then the mist started rolling in off the Great Peconic Bay. Park couldn't see her tee shot past about 150 yards on No. 18, but she just wanted to finish up to get some rest.

"With the wind and fog, it really made me think that's what the U.S. Open is all about," Park said.

PGA Tour

BETHESDA, Md. - Jordan Spieth, a 19-year-old Texan playing with nothing to lose, gave himself another chance to win going into the weekend at the AT&T National.

Spieth hit every green in regulation Friday and extended his streak to 29 holes without a bogey on a tough Congressional course, giving him a 5-under 66 and a share of the lead with Roberto Castro (69) before storms halted the second round. They were at 7-under 135, with the round to be completed this morning.

Spieth started the year with no status, uncertain where he was going to play. He now has earned over $900,000 - the equivalent of being No. 39 on the PGA Tour money list - and is assured of a tour card when the new season starts in October. But he won't be eligible for the lucrative FedEx Cup playoffs unless he's a PGA Tour member, and he can't be a member this year unless he wins.

"Honestly, I think it's a great position to be in," Spieth said. "I'm just free swinging."

PITTSBURGH - A downpour halted second-round play of the Senior Players Championship until today, with Fred Couples leading the tournament at 11-under. He was 7-under through 11 holes, ripping off seven birdies, but only 15 of 81 players completed their rounds.
