The world's top three players were grouped together, and only one — No. 1 ranked Scottie Scheffler — finished under par. Scheffler survived a pair of bogies and a double to card a 2-under 69. Rory McIlroy, meanwhile, had a rough go of it, carding a 3-over 74. Defending champ Xander Schauffele was one better at 2-over.

Rory McIlroy entered the 107th PGA Championship looking for his second straight major win, but now even making the cut is going to be difficult.

The super-grouping of the Nos. 1, 2 and 3 players in the world may have a difficult time finishing that way on the final leaderboard at the PGA Championship.
