Back-to-back birdies at the second and third moved him to minus-5, and he converted another pair of birdies at the sixth and seventh to move to 7-under.
He parred his final two holes to end there.
Sarnoff also posted a bogey-free round that included six birdies to finish a shot off the pace.
NOTES: Daniels recorded an albatross at the par-5 12th hole ... Defending champion Stephen Gangluff carded a 3-under 67 during his first round and is tied for 11th place.
