Only on the "CBS This Morning" podcast, CBS Sports golf on-course reporter Dottie Pepper joins "CBS This Morning" producer Joe Annunziato to preview the 2018 PGA Championship at the Bellerive Country Club in St. Louis. Pepper shares what we can expect this weekend as the tournament celebrates its 100th centennial, from whether Jordan Spieth will get his career grand slam to the expectations for Tiger Woods this weekend. They also discuss how the St. Louis community has come together to help get the course ready and which dark horses Pepper has her eye on.
