Veteran Karrie Webb and Marina Alex, a second-year player on the LPGA Tour, opened with 4-under-par 66s Thursday after early starts to share the first-day lead at the U.S. Women's Open in Lancaster, Pa. Their scores held up through the afternoon before things turned wet and windblown. Play was suspended in the early evening after a storm packing high winds, lightning and heavy rain pounded Lancaster Country Club.

The sudden halt to the action with 55 players left to complete their rounds — at least two of them threatening for the lead — left Webb and Alex as co-leaders.

The USGA's plan is to restart the first round at 6:45 a.m. Friday, and begin the second round 30 minutes later.

Amy Yang, who played in the morning, was in the clubhouse a shot behind the leaders. Two players on the course were also at 3 under: Na Yeon Choi, the 2012 U.S. Open champion, had three holes to play, while Jane Park had five.

Amateur Sarah Burnham of Maple Grove was 8 over after 13 holes.

Two tied a John Deere

Justin Thomas and Nicholas Thompson were tied for the lead at 8 under par after the opening round of the John Deere Classic in Silvis, Ill., while Jordan Spieth languished far behind.

Thomas and Thompson each shot a 63 at the TPC Deere Run, finishing eight strokes ahead of Masters and U.S. Open champion Spieth. They were a shot ahead of Charles Howell III and Luke Guthrie.

Three-time tournament winner Steve Stricker led a group of golfers at 6 under.

Spieth shot even-par 71 in his first round since winning the U.S. Open. Spieth, who will go for his third straight major title next week at the British Open, had three bogeys in a four-hole stretch.
