If you're wondering about the whereabouts of Southport's Tommy Fleetwood, who teed off with the overnight leader Li Haotong, he's two over for his round and four under overall after 12.

Bryson DeChambeau on his monster putt to claim a birdie on the last and card a four-under 66, leaving him six under for the week.

"I walked it off at 96 feet and said to myself, 'well, this line looks pretty good'," he said. "I was able to start it on line, it just kept going closer and closer, and eventually it dropped.

"At those moments you've just got to look back and laugh, and appreciate what the game is because that stuff happens at random points in time and this was a pretty good random moment to do it in."

By the way, he added it's the longest putt he's made - ever.

Li Haotong loses his ball after teeing off from the 13th and has to retake his drive. Dramarama!

Dustin Johnson birdies the 17th to go to nine under and the joint lead - he's set for a 65.

Defending champ Brooks Koepka, on the other hand makes, back to back bogeys. He plummets down to six under after 14 holes.

Li Haotong has just made his best putt of the championship so far - poor tee-shot and approach on the 12th, before a six-foot putt from off the green.

He lifts his arms in celebration, unlike Cameron Champ who also picks up a birdie, on the 14th, and just walks to the next tee.

They both lead the 2020 US PGA on nine under.

Scottie Scheffler finishes with a... bogey at the last. He should have finished with 64, but it's a 65 to leave him in the clubhouse on eight under - a share of the lead.

Bunker to rough for leader Scottie Scheffler on the final hole - this will be tricky.

Meanwhile, Dustin Johnson makes a birdie on the 15th to go to eight under. Johnson just has the one major to his name - the 2016 US Open - and four runners-up placings.

Mat Killeen: While playing at my local club the other week, I was told about a player in the group ahead who smashed their driver into the ground on the 5th tee and then launched a club from the 17th green to 18th tee. Also had my fair share of club drops over time.

Brooks Koepka finally moves on moving day - a birdie at the 12th sees him move to eight under.

He won't let go of the 'threepeat' without a fight.

Scottie Scheffler makes his third birdie on the bounce - on the 17th - to become the first player to go to nine under.

He is now the outright leader.

His best displays this season were third at the The American Express and Bermuda Championship.

He came into this event having finished tied 15th at a high quality St Jude competition.

Gregor Munro: Best loss of temper - junior convenor after telling me how to behave as a full member then proceeded to lose it after duffing into the burn. Full bag AND trolley thrown into burn. Picked them out and then threw back in again!

Today's round is sure to have ended Tiger Woods' hopes of a record-equalling fifth US PGA win and although he ended his 11-year wait for a 15th major last year, the 44-year-old admits his chances of closing in on Jack Nicklaus' record of 18 are fading.

"It is getting tighter and harder to win events," he said.

"When I look at the leaderboard I see the same handful of guys. They understand how to win the majors and how to plod along.

"The guys who understand how to play tough golf courses will be up there, crowds or no crowds."

Add Cameron Champ to that again thanks to his birdie at the 12th - a three-way tie at the top.

Speaking of class acts, Justin Rose, who did drop to four under, is now at seven under after another birdie - at the 11th.

The 40-year-old let out an "ooooh" as the ball tipped over into the hole

Daniel Berger birdies the 10th and Dustin Johnson does the same at the 14th.

However, Scottie Scheffler is now five under for his round and joint leader with Li Haotong at eight under after picking up a shot at the 16th.

Tiger Woods struggled on the greens for the second day running and again shot a two-over 72, leaving him two over for the week.

"I am frustrated I didn't get anything going early," he said. "I got a couple of bad angles and miss shots in spots I can't play from and I made bogeys.

"I am happy with the way I finished. It was just a fight all day and I didn't get anything going.

"I still have the last round of a major to play. Hopefully tomorrow I will shoot something in red and get it to under par for the tournament."

Tony Finau - third at last year's Open - birdies from about 60 feet on the 17th to go to six under. He's on course for a 67.

There are a lot of class acts within range.

Meanwhile, Justin Rose has pulled his mojo out of his golf bag. The former Hampshire man birdies the par five 10th, despite having found the bunker right of the green.

He's back to six under.

Martin Lloyd: Plenty of occasions where my club has gone further than the ball down the fairway.

Cameron Champ has a par putt at the 11th - very makeable - leaves his short.

His expression is similar to when he made a birdie a few moments ago - expressionless. Back to seven under.

Bryson DeChambeau produces a 100-foot birdie!! He cannot believe it!

Six under for the big man. Collin Morikawa is the clubhouse leader on seven under.
