Woody Austin, Nicholas Thompson, Briny Baird and Peter Lonard were tied on eight under par at the close of play on a weather-interrupted third day at the Zurich Classic.
More than half of the field were unable to finish their rounds at TPC Louisiana after heavy rain and lightning caused third round play to be suspended at 2:48pm.
Officials tried to bring the golfers back out later in the day and had vans loaded, but the storm intensified and the players had to return to the clubhouse.
“It’s never fun to be in a rain delay,” Austin said.
“This is two weeks in a row for me. It’s just getting kind of crazy to constantly be yanked on and off the golf course, back and forth.”
Play was officially suspended at 6:25pm with 46 golfers still on the course.
Austin was frustrated by the stoppage, which came just as he was building his momentum.
“I had momentum on my side,” Austin said.
“I just birdied 9, 10 and 11 and then got stuck for four hours. I had a nice little run going and unfortunately I wasn’t able to finish.”
At the time of the suspension, the leaderboard was still tight with only a stroke separating the leading quartet from Andres Romero, Tim Petrovic, Steve Elkington, John Merrick and clubhouse leader John Senden, one of 35 players to finish their round.
The Australian began the day in a tie for 49th but shot a six-under 66 today to reach seven under.
Thompson also made his move up the leaderboard after beginning the day in 17th position by shooting four under on the front nine.
There are 12 players who are only two strokes off the lead on six under and another nine within striking distance on five under.
