Justin Thomas explains frustrations after slow play warning at PGA Championship: "We just didn't agree"

Justin Thomas said he disagreed with the decision by tournament officials to put his group on the clock during the second round of the PGA Championship. 

Former champion Thomas comfortably made the 36-hole cut at the second men's major of the year. 

But the two-time major champion and his playing partners - Cameron Young and Keegan Bradley - were put on the clock on the fourth hole. 

All three players were spotted angrily remonstrating with a tournament official after they were informed of the decision. 

Thomas and former US Ryder Cup captain Bradley were shown on the broadcast animatedly pointing to the group in front, suggesting that they were still on the green and were keeping up. 

Pace of play was glacial on day two, with the first group out clocking a time of five hours and 30 minutes. 

"We just didn't really agree with it," Thomas told reporters after signing his card for his second consecutive 69 to sit on an overall score of two-under. 

"It's hard because it's kind of the whole time par thing. What is time par?

"How can time par on this course be the same when it's blowing 25 and the pins are tough than if it's not?

"And does time par change every day? There's just so many factors that go into it."

Thomas admitted that his group were behind. 

But he stressed: "I think that wasn't our issue or being annoyed by it, it's just the fact that we weren't holding up the group behind us. 

"It seemed like every time we were on the green, they were on the tee and so on and so forth.

"The hard part to me with the whole pace of play thing is that you, there's so much that goes into golf and there's so much that goes into hole to hole in terms of, are you hitting it close, are you able to tap it in, or you have to mark it, stuff like that, to where, are you holding the group up or are you not, to where it's very hard to make that call.

"And we just didn't agree with it, to be honest. But we got taken off, and a hole later we were caught up. 

"So it kind of goes to our point of why we didn't think we should of, but it is what it is. It's a part of it."

The aforementioned Young, who was considered by many a pre-tournament favourite for the Wanamaker Trophy, also made the cut by firing a superb 67 in blustery conditions. 

Bradley will not play the weekend after finishing on six-over after 36 holes. 

As for Thomas, his disagreement with rules officials comes 24 hours after he was criticised for his outburst of anger in round one. 

Thomas hit a wayward tee shot on the 14th hole on and decided to throw his club onto the tee box. 

There was also no evidence of a loud shout of 'fore' to warn spectators. 

The on-course behaviour of players has come under increased scrutiny after last month's Masters. 

LIV Golf recruit Sergio Garcia and Scotland's Robert MacIntyre drew the ire of Augusta National officials. 

MacIntyre directed a middle finger towards the 15th green after making a quadruple bogey whilst Garcia went to town on a tee box and snapped his driver on a water cooler. 

As part of a response, the game's governing bodies have instituted a new code of conduct where golfers are hit the penalties for actions seen as unbefitting.

Thomas wasn't the only player to attract attention in round one. 

Jon Rahm accidentally struck a volunteer in the face with a chunk of turf after angrily lashing out following a poor shot.

Rahm later apologised.
