A bevy of golfers with major titles on their resumes crowd the 2020 PGA Championship first-round leaderboard.
Two-time major winners Martin Kaymer and Zach Johnson were the first players to reach the five-under mark at TPC Harding Park.
Jason Day, Dustin Johnson, Henrik Stenson and two-time defending champion Brooks Koepka are all putting together solid rounds in the first wave of threesomes at the season's first major.
Tiger Woods could be poised for a surge further up the leaderboard to join those players if he turns in another solid nine holes after making the turn at one-under.
