Luke Donald was 7 under for the day through 14 holes before shanking a shot on the par-3 15th, the course’s signature hole.
The ball went far right off the tee, into the rocky hill on the downhill hole which features water in front of the green. The ball bounced off the rocks and rolled down the hill into the pool of water.
Donald took a double bogey on the hole to drop back to 1 over for the tournament.
First- and second-round leader Jim Furyk missed an opportunity lead the tournament from start to finish when he took a double-bogey 6 on the 18th hole after hitting his approach shot into the water in front of the green.
That dropped Furyk to 7 under, one stroke behind Anthony Kim.
Camilo Villegas, Steve Stricker and Vijay Singh are tied for third at 6 under heading into Sunday’s final round.
