Paul Casey and Brooks Koepka are having a right little chinwag on the 15th fairway. Brooks seems like he has a few stories that have tickled his playing partner.

That Golf Guy: I've decided for the next major I'm going to get a job for the PGA Tour making crowd sounds to add to the drama of the last day similar to football (soccer). How can anyone be interested in golf without a drunk shouting 'bababooey'.

Joel Dahmen completes his fourth successive round under par to finish on eight under. Exceptional display from the 32-year-old from Washington (not Tyne and Wear).

Justin Rose birdies the 16th to move to eight under - two to play.

The 40-year-old is set for another impressive finish in a major.

Andrew Priestley: Tony Finau has been excellent all year and always seems to be in contention, before his repeated Sunday struggles that is. Would love to see him finally getting across the finish line as a winner in a major championship.

Niall Davey: This has got playoff written all over this! Heard it here first...

Paul Casey, who dropped back to nine under with a bogey at the 13th, birdies the 14th after a peach of an iron. Great recovery from the 43-year-old.

Scottie Scheffler plays a very good seven iron to the six feet of the 12th green. Maybe he will be the one who pulls away from his more illustrious rivals?

American Xander Schauffele finishes with a 67 after a final round of 67.

Tony Finau becomes the fifth American on the course to move to 10 under with his birdie on the 14th. Whoops are heard from those who are peering into the Harding Park course from afar.

Who will break away?

Bryson DeChambeau from deep in the rough on the 14th kills the ball dead on the green four feet from the hole.

Superb shot - he's set to go back to nine under.

American Matthew Wolff, 21, is the clubhouse leader with 10 under after a cracking approach at the final hole. A five-under final round - superb work from the kid.

Compatriot Cameron Champ, at the 12th, makes successive bogeys to drop to eight under. Might be all over for the 25-year-old.

Paul Casey's holed two par putts from five, six, seven feet and not missed a fairway for about five holes so it does bode well for his confidence and his mindset going into the last few holes.

Jason Day's birdie putt on the 14th almost lips out but the ball circles around before dropping in - the look on the Australian's face!! Cheeky!!

He's also now at 10 under after 14.

It's all down to nerves now in the run-in.

Tony Finau judges the banana bend brilliantly on the 13th green - he moves up to nine under.

So so tough to predict how this will end...

...but not Dustin Johnson. Yikes!

He stays on 10 under while Scheffler, as expected, joins him Paul Casey and Collin Morikawa.

Scottie Scheffler is set to join the pack at 10 under after his eagle putt sidles up to the hole on the par-five 10th.

Harry H: Anyone else enjoying Watching Mr Chat BK having a shocker on Sunday?

Safe to say Harry ain't got much love for Brooks Koepka.

Los Angeles' finest Collin Morikawa makes his birdie - the 23-year-old is in a three-way tie for the lead at 10 under.

England's Ian Poulter finishes on an impressive four under after a one under round of 69. It follows his 66 on Saturday.

That Golf Guy: Birdie on 10th for Casey. English man taking the PGA Championship This is happening...isn't it? Is it? Just keep those bogeys off the card.

Aye! Aye! Korea's Si Woo Kim who's just stayed in among the peloton birdies the 15th to go to eight under.

Surely an eagle-birdie-eagle finish to upset the odds??!

Freddie Jones: Still backing Colin Morikawa myself. Surely the winner from come from the current top 11 - maybe half a chance for Dan Berger on -5?
