Dustin Johnson resides in a familiar position on top of the leaderboard after three rounds at a major.
The 2016 U.S. Open champion has been in this position three times before, but he has struggled to finish on top.
Johnson is expected to face challenges from a plethora of golfers during the final round of the 2020 PGA Championship at TPC Harding Park.
Brooks Koepka, Bryson DeChambeau and Jason Day are among the big names a few shots back and a few players that are familiar with golfing in the San Francisco area, Cameron Champ and Collin Morikawa, could make some noise as well.
