Garrigus wasted no time joining the chase with a 316-yard tee shot that left him only a 5-iron that he stuffed inside 3 feet on the 530-yard fourth hole. He followed by driving through the green on the 329-yard fourth hole into a back bunker for an up-and-down, then made another strong move around the turn with three birdies in a four-hole stretch, courtesy of a couple of tricky putts.
The third round started late and in threesomes to cope with overnight rain, though Hamilton began to dry out in the afternoon. Proof of that was the 3-iron Garrigus hit off the 18th tee to stay well short of the creek. He was stunned to see it go through the fairway near the bridge.
The forecast Sunday is for sunshine, which could make Hamilton the test it typically is.
Kirk, who began the third round six shots behind. Starting with the third hole, Kirk made seven birdies in an eight-hole stretch. He was 7 under for his round with eight holes remaining, needing birdie on half of them for a 59. He was never thinking about golf's magic number, though, which was a good thing. He closed with eight pars, and he was OK with that.
"I was just trying to keep my head down and keep going," he said. "When you have those days where everything is going in the hole, you make as many as you can."
