McIlroy came in as the co-favorite, but his long-time dominance didn't show up in the first round as he struggled to a 74

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 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.
