Rory McIlroy shot a first-round 67 on Day One of the US PGA Championship, but what were the other highlights from the opening day's play?

BBC Sport's Conor McNamara selects his best moments from Day One at Kiawah Island.

Shot of the Day

Tiger Woods's chip onto the green on his last hole of the day. The former world number one missed the green with his approach shot and was left with a very difficult chip. He planted a magnificent flop shot to within six feet and saved par.

Performance of the Day

Carl Pettersson's 66 took full advantage of the good scoring conditions. The Swede knows his way around the Ocean Course, having won a tournament here in April. Evidence of his length off the tee is provided by the fact that he picked up birdies at three of the four par-five holes on the course.

Collapse of the Day

Joost Luiten was threatening the course record of 63 at eight-under-par through 14 holes, but then with echoes of Adam Scott's late collapse at the Open, the Dutchman dropped shots at each of the last four holes and had to settle for 68.

Word of the Day

Paspalum. Paspalum is the variety of grass used on the Kiawah Island course. It is very thick. This allows the players to be aggressive with their approach shots to the pins. Paspalum grass 'bites' the ball and stops it quickly, so players don't have to worry about it rolling past the target once it bounces.

While pictures of Kiawah Island make it look like a links course, the paspalum grass ensures that the Ocean Course does not play like links. Players cannot 'bump and run' shots like they would on a links because the grass is too thick.
