Snedeker, ranked 38th and one of only three players in the top 100 at Royal Pines this week, was 7 over after five holes. Starting on the back nine, he had two bogeys, a double bogey and a triple bogey to start and made the turn in 9-over 45.
On his last nine, he had four bogeys and his only birdie of the day, on the par-4 sixth.
The course played tough early with rain showers and gusting winds.
Two years ago, Snedeker was a late withdrawal from the Australian PGA when he injured his knee after falling off a Segway at a tournament in China.
