Woods was the winner in 2000 while compatriot Mark Brooks - playing with fellow past champions John Daly (1991) and Rich Beem (2002) at 13:30 - was victorious in 1996, the first major tournament at the Jack Nicklaus-designed course.
Defending champion Jason Dufner tees off at 18:55 with 2011 winner Keegan Bradley and 2009 victor YE Yang of South Korea.
