The four-time champion returns after taking part in just seven tournaments this year due to ankle and knee injuries.
Woods, who played at a tournament in Akron last week, revealed that he is confident heading into today’s event.
"I can feel the rush of a major championship again,” he said. "I can just feel the atmosphere - it's just different.
"I was frustrated earlier in the year, especially at The Masters, because I just wasn't feeling well, but now that I'm healthy I have way more energy because I'm not trying to block out pain.
"I can just go out there and play golf."
The 35-year-old has won 14 majors and 71 PGA tour events in total during his career.
