As the US PGA tour continues in earnest, there have been a number of remarkable things that have taken place. From Rory McIlroy's fantastic shot to save par on Friday to Rod Pampling's awful one, it certainly has been a tournament to remember so far.

The tour continues to produce moments of levity, one of which was the light hearted exchange between golfers Jason Day and Dustin Johnson. 

Day managed to card a more than respectable five under 66 to place himself firmly in the running despite the terrible weather at the notoriously tricky Quail Hollow course on Friday.

Johnson had offered to rush his tee shot at the 18th hole which would have allowed the group to then finish their second rounds after the horn blew.

Had the horn blown before Johnson had struck his drive, the players would have faced a very early start on day three to conclude the round.

Afterwards, Day explained that he hugged his rival Johnson during the second round of the tournament to thank him for his unselfish gesture.

"I was hugging him. On 17, I was off the green. And we were walking up, and we were talking about like if we can get a tee shot on 18, we could finish the round," he said, as per Yahoo Sport.

"And DJ [Johnson] is like, 'I'll do it.' And I'm like, 'That's great.'

"As soon as he teed off, we all kind of flushed it down 18. And I just walked up to him and said, 'That's the biggest, or most clutch thing I've ever seen anyone do for me.'

"I had to give him a hug for it. He was happy, as well. Obviously to be able to finish and not have to wake up at 05:30 tomorrow, get some rest.

"To be able to get that extra sleep and relax a little bit in the afternoon; it goes for Henrik, and Dustin, as well. They wouldn't have that quick turnaround if they needed it."

The sportsmanship shown on the tour so far has been exceptional. Australian, Rod Pampling also did something similar, assisting his fellow golfers by rushing one of his shots.

At the halfway stage, Day is in third and sits just two shots behind co-leaders Hideki Matsuyama and Kevin Kisner.
