An error on the tv pictures... Matthieu Pavon is in for par on the 10th, not the birdie as advertised.

Still, it's a great start for the Frenchman.

I still wonder if Rory McIlroy has been watching - what he'd give for four birdies in his opening 10 holes... and no bogeys.

Viktor Hovland lands a 30-foot bomb on the 17th green to pick up another birdie, but Bryson DeChambeau has to wrk extremely hard to make his par after a poor tee shot.

He chips on to 10 feet and then manages to land the putt, giving it a mini fist pump as he knows he's got away with one there.

Just as I was lavishing praise on Max Homa, he duffs up the 13th hole.

Overcooking the green with his tee shot, fluffing his chip so that it doesn't escape the rough and then scrambling out to leave two feet for bogey.

That's a shot coughed up but still a marvellous round from the Californian.

Another shot gone for Tyrrell Hatton and he's going backwards at a rate of knots.

A wayward second into greenside rough on the second ultimately costs him a bogey as he misses the 10-foot par putt.

We have another American manoeuvring himself up the leaderboard as Michael Thorbjornsen joins Aaron Rai and Max Homa at five under par.

The 23-year-old only turned pro last year and has three missed cuts at US Opens as his majors back story.

He also gives himself a chance of a share of the lead with a birdie putt at the eighth but drags it wide.

Fine debut at the US PGA so far.

Oh dear, that is one ugly looking card for Ludvig Aberg now as he makes another double bogey at the 18th, with a sloppy bunker shot followed by a chip that didn;t make it up the green and fell back down Ludvig Aberg-style.

That six makes it back-to-back double bogeys for Aberg who has finished his front nine in bogey-double-double so that's five shots gone over the Green Mile.

Wow!

Chance for Aaron Rai to move level at the top of the leaderboard but his birdie putt skips by the 10th hole.

He'll stay one back alongside the charging Max Homa.

Close but no cigar against for Jhonattan Vegas, who leaves himself 14 feet on the sixth from his tee shot, but he just fails to make it drop. It's another par for the leader.

Few players can play a 526-yard par four quite like Bryson DeChambeau, who smacks a drive 359 yards to make it a comfortable second, which he plays to 17 feet - so good, but not great from 160 yards out.

Still, his long putter does the trick as he picks up his second birdie of the day to improve to two under. Pretty solid stuff so far from bogey-free Bryson.

Oh boy, Max Homa! Daylight robbery on the third hole (his 12th) but he is having a day.

It's a ballooned tee shot into the thick stuff but a fine recovery to pick out the green.

And then topped off by a wonderful downhill birdie putt from over 20 feet.

Magnificent round of seven under par so far - and he's only one off the lead!

Cam Davis slips back out of solo second after a back-to-back bogeys on the 11th and 12th threaten to derail his entire tournament.

He's unlucly on 12 really as he lands his approach on the green but it spins too much and then tumbles off that huge slope that guards the putting surface, and he takes three from there to drop to three under.

The triple bogey on 18 is firmly in the rearview mirror for Tyrrell Hatton has he finds the green with his second to the par-four first.

The 25-footer for birdie stays above ground but a solid par was required.

Disaster for Ludvig Aberg at the 17th - which is playing 40 yards shorter than yesterday at just 185 yards but is seemingly still just as tough.

Aberg hooks his tee shot into the water, and then almosty spins his third back into the soup too, as it's a nasty little 98-yard pitch over the lake from the drop zone.

That's a double bogey for Aberg and three shots gone in two holes.

Viktor Hovland gets the birdie he'd been threatening over the last few holes as he makes a four on the par-five 15th - thanks to his short game skills out of the sand.

The Norwegian hits the front bunker but plays a majestic escape down to just three feet, which he rolls in to move to two under.

Bryson DeChambeau unsurprisingly found the green in two, but then three-putted from 50 feet as he blazed his initial effort 14 foot past.

What do they say? Driving for dough...

Another American joins the crowd jostling for position two behind the leader as JJ Spaun moves to four under par.

Starting day two at level, the runner-up to Rory McIlroy at this year's Players Championship has five birdies on his card today.

The 18th is wreaking more havoc. Collin Morikawa is the latest to tug his drive into the water. And because rough flanks both sides of the stream, the drop isn't particularly comfortable, into thick vegetation that he can only hack his ball down the fairway out of it.

His fourth shot thuds into the front of the green and spins back off. A chip and a putt and that's a double bogey.

Justin Thomas found the green in two shots but smashes his putt through the break to leave a testy seven-footer for par. He's not up to it. A three-putt bogey and JT is trudging off the green, muttering to himself, presumably wondering how he's back where he started the day.

Jhonattan Vegas is just warming to the task a bit more now - as after leaving himself 14 feet for a birdie on four he's got the same on the fifth.

Again, he misses but at least he's getting some decent birdie looks now and seems to be calming himself down and finding his stride again.

Eight minutes after bogeying to slip out of second place, Aaron Rai is back in the slipstream of the leader.

Stunning approach shot into the ninth hole sets up an eight-foot birdie putt that he duly rolls home.

Cracking comeback from the Englishman who has four birdies and three bogeys from his opening nine holes.

A rare sight of England's Matt Walace. He's desperate to get into the Ryder Cup team and a birdie on the fifth to get him back to level par keeps him in the picture this week.

He's got form at Ryder Cup venue Bethpage Black too - he finished top three in the 2019 US PGA.

There are plenty of birdie opportunities out there today and France's Matthieu Pavon is taking advantage of the benign conditions. He's just knocked in a fourth birdie in his opening eight holes and he's just two off the lead.
