The PGA Championship returns this week to Southern Hills Golf Club in Tulsa, Okla., 15 years after Tiger Woods won the 13th of his 15 major championships there in 2007. Woods is back in the field, but, just like the Masters, defending champ Phil Mickelson is not. Post-Gazette golf writer Gerry Dulac handicaps the top 20 contenders for the second major of the season and predicts the winner.
— Scottie Scheffler: That green jacket he won last month was no fluke.
— Jordan Spieth: A victory and a solo second in his past two tour starts.
