The PGA Championship is on its way toward being decided Sunday with the Wanamaker Trophy on the line for the 100th time in its history. And if early play is indication, there should be plenty of fireworks coming home during Round 4 at Bellerive Country Club.

Strap in for complete coverage of the PGA Championship on Sunday from both CBS Sports and TNT.
