Tiger Woods held a three-way share of the overnight lead at the end of Day Two of the US PGA Championship, but what were the other highlights from the second day's play?
BBC Sport's Conor McNamara selects his best moments from Day Two at Kiawah Island.
Worst Shot of the Day
Rory McIlroy's birdie attempt at the 15th was remarkable - as soft a putt as you will ever see from a professional. From around 25 feet McIlroy failed to hit the ball even half that distance. It appeared that he hit the ground before striking the ball. Clearly rattled, McIlroy then missed his second putt too and suffered a bogey. The Northern Irishman did well to recover from that setback to steady his round and remain in serious contention for the weekend, just two shots off the lead.
Stroke of the Day
Not once - but twice - Tiger Woods saw putts swivel a full 360 degrees around the cup and drop in. The first one at the 10th hole seemed to lip around the mouth of the hole and actually pop up in the air before dropping in. These 'round the world' shots, as they call them here in the US, returned a smile to the face of Tiger Woods that we have not seen for a long time.
He didn't have it all go his way, however - a bobble at the 18th green forced a three-putt to finish Woods's round with a bogey.
Phantom Comeback of the Day
Northern Ireland's Michael Hoey seemed destined to miss the cut after a six-over-par 78 during the calm weather on Thursday. Hoey, though, rose to the occasion in the wind on the second day to card the second best round of the day, a fantastic two-under-par 70. It lifted him a massive 90 places on the leaderboard.
However, Hoey was later disqualified for 'failing to recreate his lie' after brushing sand off his ball to identify it. He should have replaced the sand as he found it. Hoey's card would have been good enough to make the cut, but now he will not be here for the weekend.
Number of the Day (38)
A high gust of 38 mph was recorded on the ocean course during round one. Welshman Jamie Donaldson told me his ball had been oscillating when stationary on the greens. Had the winds been any stronger and actually forced the balls to move, the players would have been called in.
Stat of the Day
The scoring average at the end of play on Friday was 78.11. That is the highest for a single round in PGA Championship history since the first round of the first PGA Championship to be played using strokeplay in 1958.
Performance of the Day
Vijay Singh. The Fijian was the only player in the field to score in the 60s during the second round - a remarkable feat given the windy conditions. American golfer Ricky Fowler later wrote on Twitter: "Not sure where Vijay was playing today…" Fowler himself struggled badly in the wind, finishing 10 over par, and missed the cut.
