The PGA of America said Friday that Woods was among the first four players to enter. The others were Masters champion Phil Mickelson, U.S. Open champion Graeme McDowell and two-time PGA champion Vijay Singh.
The PGA Championship will be played Aug. 12-15 at Whistling Straits, where Singh won in a three-man playoff in 2004.
Woods was the runner-up at the PGA Championship last year, losing a two-shot lead in the final round to Y.E. Yang, who became the first Asian male to win a major. It was the first time Woods had blown a lead going into the final round of a major.
Woods was in the middle of a swing change at Whistling Straits in 2004 and tied for 24th.
