Scottie Scheffler confirms report over Rory McIlroy driver controversy

Scottie Scheffler has confirmed he was asked to change driver before the PGA Championship. 

A visibly emotional Scheffler held off a rejuvenated Jon Rahm on Sunday to claim his third major title at Quail Hollow Club. 

Scheffler began the day with a three-stroke advantage and eventually won by five after an 'embarrassed' Rahm collapsed down the stretch. 

None of the other chasers were able to reel in the two-time Masters champ despite the 28-year-old enduring a patchy front nine in which he fought the lefts with his driver. 

Driver testing was a hot topic all week after reports emerged Rory McIlroy was forced into a late equipment switch. 

USGA officials deemed McIlroy's TaylorMade Qi10 driver 'non-conforming' after the club failed at CT test.

CT tests determine if a driver's face is too springy. 

McIlroy decided to not to speak with the media all week so we are yet to hear his side of the story. 

Scheffler's Ryder Cup teammate Xander Schauffele hinted Scheffler was also forced to change his gamer when he spoke to Golfweek after the fourth round. 

Scheffler confirmed this was the case when asked by a reporter in his news conference shortly after he dropped the lid of the Wanamaker Trophy.

The reporter asked: "How did that go? Did it have anything to do with hitting it left today?"

Scheffler replied: "No, I think that was my fault.

"So the driver testing is something that regularly happens on Tour. My driver did fail me this week. 

"We had a feeling that it was going to be coming because I've used that driver for over a year. I was kind of fortunate for it to last that long, I felt like."

Schauffele had strong opinions on the topic and he believes every player's driver should be tested in the future to protect the integrity of the sport.

Scheffler agreed. 

"I would argue that if we're going to test the drivers, we need to be even more robust in the way we test them," Scheffler said. 

"That was a conversation I had with one of the rules officials; if it's something we're going to take seriously, I feel like we're almost going halfway with it right now."

"If we're going to test only a third of the field. If we're going to do it right, leave it up to us as players, like the rest of the rules in the game of golf are."

Scheffler added: "It's a newer rule that we haven't quite gotten right yet. I think we have some stuff to figure out. 

"I think, if we're going to do it, we might as well do it right, get more robust and get even more strict. 

"You can test guys every week, if you want. I mean, there's no reason why we shouldn't."
