"It's fun to go out and shoot 62s and 63s," said Hampshire, who fired a 63 in the third round of last week's Price Cutter Charity Championship en route to a T3 finish. "You know it's going to be a birdie barrage and you try to make as many as you can. You stay aggressive. The greens are soft enough that you can throw it right at the holes."
Just about the entire field took dead aim at the flags. The scoring average for the par-71 layout was 68.862 as 118 players in the 156-man field posted scores below par.
"It's a good feeling to shoot something low," said Hampshire, who had 10 birdies in the round. "You get more and more comfortable doing it."
Nobody is more comfortable than Killeen these days. The 29-year old Texan is looking for his third win in four weeks. Another victory here would earn the former TCU standout an immediate promotion to the PGA TOUR.
"It'd be great to win again. I've got the same mentality I had for the other events," said Killeen, who missed the cut last week after posting back-to-back winning scores of 22-under par. "Everybody's goal out here is to move on to the PGA TOUR and knowing that you're already doing that does feel like you're playing with 'house money' and so you're a little calmer."
His relaxed attitude has propelled him to No. 2 on the money which has essentially locked him up a spot on TOUR in 2012.
"I really have played well the whole year. It's just that right now all parts of my game are really sharp," said Killeen, whose 2-over 74 to begin last week was the only time he's been above-par after the first day in 15 starts this year. "I took advantage of a couple opportunities and got a couple of good breaks and that's how you shoot a really low score."
Killeen needed only 22 putts to post his 63, the 18th sub-par score in his last 19 rounds. Hampshire had 25 putts and Thompson just 26.
"Numbers-wise, this course just falls into what we've been seeing the last four weeks," said Thompson, who is 41-under in his last three starts. "You've got to pick a good game plan for the golf course and there you have to select the pins you want to go at. I have a pretty aggressive plan for this week. I like the way the course sets up for a driver."
• The four-way tie for first place is the most players tied after 18 holes this year. Today's four-way tie represents the most players sharing the first-round lead since six players were after the first round at 2010 Panama Claro Championship (5-under 65).
