Rory McIlroy's first round at the PGA Championship was a rollercoaster—and not the fun kind. The four-time major winner carded a frustrating 4-over 74, undone by wild drives and a disastrous finish that saw him bogey the final four holes.

Off the tee, McIlroy found just five of 14 fairways, a stat that had him visibly cursing his waywardness. "It's just not good enough," he said after the round. "You can't win a major hitting it like that." For a player known for his explosive power and precision, this was a rare off day—and at a major, those mistakes cost dearly.

The back nine collapse was particularly painful. After a solid start, McIlroy's game unravelled as the pressure mounted, leaving him well off the pace early in the tournament. With three more rounds to go, he'll need to find his rhythm fast—and that starts with finding the fairway.
