It all comes down to this. After three days of exciting action, the PGA Championship will be decided with Sunday's final round at TPC Harding Park in San Francisco. And there are some strong contenders at the top of the leaderboard who will be battling for the win at the first major tournament of 2020.
Dustin Johnson is currently in the lead at nine under par, as he shot a five-under 65 for his best round of the tournament so far on Saturday. But he has only a one-stroke lead over Scottie Scheffler and Cameron Champ and a two-stroke lead over the trio of Collin Morikawa, Paul Casey and Brooks Koepka, the two-time defending champion.
