Justin Rose given two-shot penalty at PGA Tour event for breaking golf rule

Justin Rose was praised by golf fans after he self-reported a violation of the rules during the second round of the RBC Canadian Open.

Rose arrived at TPC Toronto's par-3 seventh on Friday having begun the day well. 

Birdies at the third and fifth had lifted the Englishman to a 3-under total for the tournament and comfortably inside the projected cut.

But he was later assessed a two-shot penalty for causing his golf ball to move before playing his second shot. 

What happened?

Rose hit an impressive 194-yard shank with his tee shot. 

His golf ball darted straight right, cleared the water in front of the green and settled some 50 yards from the pin in the thick rough. 

The European Ryder Cup veteran took a few moments to assess his options and tried to clear a loose impediment next to his ball.

Unfortunately his ball moved. Perhaps Rose a tad flustered in the moment as he failed to move Titleist ProV1x back to its original position.

It resulted in a two-shot penalty. Infuriatingly for Rose, had he put the ball back he would've only been docked one stroke. 

Rose reported the incident, according to the PGA Tour LIVE broadcast.

Orlando Pope, the senior director of TV rules, told the broadcast: "I'm not sure he knew he had to put the ball back. 

"So he didn't put the ball back and went ahead and played.

"So, since he caused the ball to move and didn't put it back, he gets the general penalty, which is a two-shot penalty."

Rose got up and down for a double bogey and made par on his final two holes. 

His score of 71 left him on 1-under after 36 holes and two outside the projected cut. 

It will be a particularly difficult pill for Rose to swallow. 

He has struggled for form since losing to Rory McIlroy in a playoff at The Masters in April. 

Rose followed his second playoff heartbreak at Augusta National with a missed cut at the PGA Championship after shooting rounds of 76-75 at Quail Hollow. 

He finished in a share for 44th at last week's Memorial Tournament. 

Cameron Champ opens up a three-shot lead

Earlier in the day American Cameron Champ hit the front in Canada with a superb 4-under 66 in difficult conditions. 

Champ is searching for his first win since the 2021 3M Open. 

Denmark's Thorbjorn Olesen, New Zealand's Ryan Fox and European Ryder Cup hopefuls Shane Lowry and Nicolai Hojgaard after in the top 10 after 36 holes in Canada. 

The aforementioned McIlroy made a terrible start to his second round, carding a quadruple bogey eight at the par-4 fourth.
