Matt Kuchar of the United States hits his tee shot on the second hole during the first round of the 114th US Open on June 12, 2014 in Pinehurst, North Carolina - by Mike Ehrmann
World number five Kuchar, a winner at the US PGA Heritage tournament in April, opened and closed the front nine with birdies and added another at the par-5 fifth.
Jordan Spieth, the 20-year-old Masters runner-up, shared second on two-under with fellow American Clayton Rask and Sweden's Henrik Norlander.
Snedeker, who had reached four-under after starting with a 31 on the front nine, fell into a pack at one-under.
Also in that group was five-time major champion Phil Mickelson, a six-time US open runner-up trying to complete a career grand slam, and past major winners Graeme McDowell, Webb Simpson and David Toms.
The one-under group also included India's Shiv Kapur and a trio of amateurs -- US Amateur winner Matthew Fitzpatrick of England, American Maverick McNealy and Australian Oliver Goss.
