Snedeker began the first round with a bogey 5 on the par-4 10th, his first hole of the round.
The putt sealed his 10th birdie of the day on a card also featuring one bogey and an eagle, secured when his 176-yard approach on the par-four sixth went in.
"I got so excited, goosebumps. jumping around like I won the golf tournament and it's Thursday morning", Snedeker said. "I knocked that putt in".
"I feel like I don't have any pressure on me right now", echoed Silverman.
Jim Furyk holds the record with a 58. Snedeker also is the fourth PGA Tour player to break 60 in the past three years; there were only four to do it in the previous 24 years. "Obviously I'd like to be in a slightly different position ideally, but still have a good chance", said Conners, who spent last week at home visiting friends and enjoying a rare week off. "I don't know how you wouldn't", Snedeker said of his mindset during the round. He remembered a non-tour event he played in China in which he was one putt from that score, but those thoughts "got in the way".
"Walking to the ninth tee I kept telling myself "I can not let this opportunity get out of my hands", he said, and he didn't".

Moore, who won here in 2009, made a move up the leaderboard in the afternoon with five birdies in a six-hole span on the front nine.
But at the par-4 eighth, Snedeker missed a six-foot birdie putt and tapped in for par.
"Could have been even more special", he said, "but happy with the way everything turned out".
It's the 10th sub-60 round in Tour history and first since Adam Hadwin shot 59 at last year's CareerBuilder Challenge in January.
"I was pretty upset [after the eighth] because I knew you're not going to have many good looks to shoot 59", Snedeker told PGA Tour Live.
