The PGA Championship celebrates its 100th anniversary this year at Bellerive Country Club, located outside of St. Louis, on Aug 9-12. After all the pageantry, and while Justin Thomas looks to defend the title he won at Quail Hollow Club in 2017, much of the focus will undoubtedly shift to Tiger Woods in the year's final major tournament.

Woods drew international headlines when he briefly led at the British Open before finishing tied for sixth. It was an impressive run for Woods at Carnoustie, where the margin for error was minimal.

Only four golfers have better odds than Woods to win at Bellerive. According to Bet365, Dustin Johnson, Rory McIlroy and Jordan Spieth all have 12/1 odds to win the major. Justin Rose is listed at 18/1.

Woods has 20/1 odds of winning the tournament, sharing the odds with four others: Thomas, Rickie Fowler, Brooks Koepka and British Open winner Francesco Molinari., meanwhile, gives Woods 16/1 odds.

Oddsmakers have mostly been generous with Woods. He had entered the Masters as the co-favorite at 10/1. At the U.S. Open he had 20/1 odds and his British Open odds were as high as 18/1. It was only in Scotland that Woods looked like he had a legitimate shot of ending a major-title drought that now dates back more than a decade.

But after injuries and personal troubles, Woods appears to have recaptured his former top form. The 42-year-old has surged in the world golf rankings — from No. 71 to No. 50 — which is a major development for the 14-time major winner who had earlier this year admitted that he wasn't sure if he could ever play again.

Woods will need to maintain his patience and focus in Missouri. Bellerive promises to be a particularly challenging course, with deep bunkers and wide greens.
