Drops a shot at the mammoth 481-yard par-four fifth. He had about 14ft uphill for par to preserve his one-under score but it crept past on the left. McIlroy makes a gritty par-saving up and down on the second.
Big Jon Rahm
Makes birdie at the first but then has a 25-footer for another at the third. He attacks it aggressively and it lips out on the left and rolls 9ft past. Had he lagged it he would have been guaranteed for -1 but he misses and has to take the hit.
Rough start for McIlroy
Who begins his round with a bogey - as does Dustin Johnson and as did John Daly for whom four wheels good-two legs bad.
Paul Casey off to a flyer
The Englishman, who missed the cut in the US PGA in 2018, has birdied the second and the fourth (he's playing the course the orthodox way). He is in a tie for third along with Mike Lorenzo-Vera, Tony Finau, Chez Reavie and Luke List who double-bogeyed 17 and birdied 18. It's a brute of a set-up on the Black Course.
Meanwhile McIlroy begins his round and is struggling, leaving himself a tricky 12-footer for par.
Up on the ninth
Where the featured group are finishing their first rounds Koepka sweeps in a 28ft monster for birdie to end the round with a 63, -7. Not a single bogey on his immaculate card. Woods has a tiddler for par and makes it to end nine-strokes back in +2, the same score as Molinari.
Woods drops another stroke at the 8th
He is two-over after 17 holes now. His second stroke left him a long putt for par which he hooked past the cup. Koepka shows him the way to stay at six-under with one to play, three ahead of the clubhouse leader Fleetwood and LL Cool Luke List.
Justin Rose wobbles
Four birdies and four bogeys on this hellishly difficult course. He is on even par with one to play.
Meanwhile at the par four 15th, Luke List has missed an uphill 5ft putt for par and slips back to -3, tied for second with Tommy Fleetwood who has just been interviewed and said if you miss the fairway you have to accept it's going to be very difficult to avoid a bogey.
Two bogeys in three for Woods and Molinari
At the par-four seventh both miss short putts for par. Koepka shoes them how to do it and marches on to the eighth tee looking unassailable at -6 with two to play.
Fleetwood bounces back
At the ninth (his 18th) after a terrific second stroke that gave him a birdie putt from 5ft. He drains it and signs for three-under.
Luke List into second
With his birdie at the par five 13th. List is ranked 76th in the world and missed the cut in this tournament in both 2017 and 2018. Fourteen months ago he lost in a playoff with Justin Thomas for the Honda Classic which was his best tournament to date.
Koepka scrambles for par at six
He recovers from his wayward drive and hack out of the rough into a bunker to chip it out of the sand to 12ft. From there he rattles his putt into the cup to stay on -6. Molinari and Woods also save par. On we go.
Fleetwood drops back
After bogeying the par three eighth (his 17th). Mike Lorenzo-Vera, from beautiful Bayonne in Gascony, is the clubhouse leader after birdies at 16 and 18. He's on -2, tied for third overall.
A twitch on the thread from Matt Wallace
Hillingdon's finest, who made four birdies in his first six holes and three bogeys in the next five, has birdied the 12th to move back up to -2 and sole ownership of fourth-place.
Back with the featured groups, Woods had a monster for birdie at the par-four 5th. The New York crowd tried to shout it into the hole but it slid past. Koepka has a 12-footer and sweeps it into the cup. The birdie extends his lead to three strokes at -6 while Molinari cannot scramble par and drops a shot. He's on +1.
And Woods, to the dismay of the gallery and the commentators, three-putts to bohey, his par effort horseshoeing out from 6ft.
Eagle for Woods
Koepka has a poor lie and cannot get his third stroke on to the green. He chips his fourth about 6ft to the right of the hole and he should save par. Molinari is on in four and has a very tricky 15ft for par but before he can take it, Woods rattles in his 35ft for eagle! Woods goes to -1 and a tie for fifth. Remarkable, give double-bogeys at 10 and 17.
Molinari who zigzagged up the hole, never finding the fairway, sinks his awkward par-saver and so does Koepka from closer in.
Molinari in trouble
Molinari is in the fairway bunker from the tee at the fourth (his 13th) and thins his wedge out of it. The ball hits the lip of the bunker and plonks on to the fairway about 20 yards away with a long, long way to go. Koepka is in deep rough about 190 yards from the hole. Woods is on the fairway and get on to the green in two, giving himself about 40ft for eagle.
If it feels this is all too Woods centric, I do sympathise. We only have featured groups coverage until 6pm and then the contract the US PGA has made with the broadcaster allows them to show everyone. And American networks ensure Woods is always in the principal featured group.
Koepka pitches out of the rough and about 25 yards short of the green.
Koepka races away
Luke List, a 33-year-old Vanderbilt graduate, has made his fourth birdied of the day at the ninth to move up to a tie for second place with Fleetwood on -3.
Molinari is above the pin and pushes it down the hill from about 14ft. It slides by on the right and trickles 4ft past. Koepka drills his birdie putt into the heart of the cup from 11ft to extend his lead on -5. Last up is Woods from 8ft who misreads the break and speed and it dies to the left. Par for Woods and Molinari.
Fleetwood drops back
Tommy Fleetwood, who bogeyed the 10th, his first hole, has just bogeyed the 14th, making a five at the par-four. Koepka's tee shot at the par-three third is pitched to within 15ft ... as does Woods ... as does Molinari. Each has a fine birdie chance.
Woods makes back-to-back birdies
Good afternoon. Sky is stuck with the leading groups for a while longer so chances of catching up with some of the Englishmen towards the top of the leaderboard are slim right now. Still, we have the pleasure of watching the Open champion, Francesco Molinari and the defending champion, Brooks Koepka, who is playing like a dream. Woods is in this group, too, and has made the best approach to the 2nd, leaving him maybe 5ft for birdie. Molinari is close to the pin but off the green and Koepka has about 10ft for birdie. The ball should break to the right.
If he sinks this he will go to -5, but he pushes it to the left of the cup and rolls a tiddler in for par. Woods nails back-to-back birdies to move up to +1 and Molinari sweeps in his par-putt to stay on level.
Fleetwood and Koepka are tied for the lead on 4-under.
Koepka looking ominously good
Woods might not be too bad for line, but he is in the rough so will have no control of distance. He gets a nice break however, and his second bounces off the bank on the right side of the green and feeds down to the hole. Less than 20 feet for birdie coming up.
That's outrageous from Koepka...a Houdini act from the right trees for a kick-in birdie. The defending champ now leads on his won.
Good news for Woods fans, could this be the moment that gives him some mojo? Takes advantage off the kind bounce by rolling his birdie putt right into the heart.
Back to two-over and the grind continues.
That's all from me, I shall leave you with Rob Bagchi for the evening session.
Possible trouble for Koepka at the first
The first is a very gentle par-four that meanders from left to right. That's a dreadful slice from Koepka that sails way too far right and could be blocked out. Woods also tries to cut the corner, and some shoddy camera work means it's not clear whether it made the full carry. If not he may have tree trouble.
Koepka now tied for the lead
A little too firm on the line he chose from Woods, and he will settle for par at the 18th. That's a three-over par 'front' nine of 38 and he needs something under par coming home.
Molinari makes his second birdie to three holes to get back to level par, and Koepka drains his putt too and the defending champion is tied for the lead at three-under with Fleetwood and Wallace.
Everyone in good shape at the 18th
Chance of a bounce back for Woods, who sends a nine iron over the flag and 18 and will have 15 feet for birdie coming back. Looked like he was between nine and wedge, and swung easy with the longer club so it had a little less spin on it. Molinari in there close too.
Koepka did swing hard with some kind of wedge, and he consequently gets more spin. Rips back past the hole and he will have less than feet up hill for birdie.
To the 18th
Right down the pipe at the 18th from Woods and Koepka, but you have to say it's the latter who looks the stronger contender for the Wanamaker Trophy. Matt Wallace now all alone at four-under and he leads by two. The Englishman is not afraid to win, and not afraid to let people know about it either.
Woods tumbles back down the board
Woods' tee shot ended up in a horrible spot, half-buried in the face of the bunker and the ball races through to the back of the green. Looking like his first dropped shot since the 10th.
And it could be worse than that as Woods races his return putt a good 10 feet past. And he pushed the bogey putt past and that's the second big mistake of the day...double bogey five drops back to two-over.
Wonderful amphitheatre at the 17th...
Woods and Molinari both fell victim of a freshening breeze and came up short in the bunker.
Englishmen in New York are going well
Wonderfully executed pitch from Woods who has just a couple of feet left to save par. That scared the hole on the way past.
Three Englishman at the top of the leaderboard now...Hatton, Fleetwood and Wallace.
Confidently done by Woods and that is a good escape at the 16th. Birdie for Molinari and par for Koepka.
Tiger unable to reach the green from rough
That's more like it from Molinari who fires an iron shot to within a few feet at the 16th...looking like a bounce back birdie for the Italian.
What can Tiger do from the rough? Pounds down on it, and it comes out low and running...gets it in the mouth of the green and will have a 40 yard pitch coming up to save par. Test of short game coming up.
This will test Woods' strength
That's a little too far left for Woods at the 16th, another stern par four, but it is a slight dog-leg right so at least he has an angle to work with.
Some strong English challenges simmering out there: Matt Wallace leads at three-under while Tyrrell Hatton is at two.
Tiger on the move! First birdie of the day for Woods and it comes at the difficult 15th, as he judges a fast left-to-right putt from around 15 feet back to Molinari. Back to one-over.
Koepka pars, but Molinari three-putts and he falls back to two-over.
Vintage Tiger there
Best shot of the day from Woods, who drills an iron from more than 200 yards with a touch of draw, knowing the contours of Bethpage will sweep his ball from the left edge back towards the hole. Will have a slippery 15 foot putt down the hill for birdie.
Koepka gouges one out into the middle of the green, a superb recover from where he was.
Fairway found for Woods at 15
A rare mistake from Koepka who allows his drive at the tough 15th to get away to the right. This green sits a good 40 feet above the player so it's so important to find the fairway and create some spin with the second.
Short stuff for Molinari, and nicely done too by Woods who finds the right side of the fairway. He is definetly warming to his task.
Koepka moving again...
This is turning out to be more stressful than it needs to be. Woods runs his first putt up the hill and a good four feet or so past.
Another tram-liner from Koepka finds the bottom of the cup and he joins the leaders at two-under! His name casts a shadow over the leaderboard at major championships. Better news too for Molinari, who rolls in his first birdie of the day to get back to one-over.
Woods holds his nerve, and rolls in the return putt to stay at two-over. If he could reach the turn at that score it would be more than acceptable after a double-bogey start. Holes 1 thru 4 are arguably the easiest stretch on the course.
All aboard at 14
Right on line from Koepka at the short 14th, but it does not quite make it all the way back to the shelf where the hole is located.
Woods up next...likewise, that iron shot looked fantastic in the air but just lacked a couple of yards of carry. Middle of the dance floor and no harm done.
Molinari had the advantage of going third there, and he does get the ball all the way back there. About 10 feet coming up for birdie for the Champion Golfer of the Year.
An idea of how thick the rough is..you cannot see Woods' shoes
Fives all round
Another mid-judged wedge shot by Tiger Woods that flies through the back of the 13th green. That looks the department of his game short of sharpness in the early stages.
Plays a nice pitch from the rough though, and it trickles down to within a couple of feet. All pars at the 13th for Woods, Koepka and Molinari and they move on to their first par-three.
Charley Hoffman and Matt Wallace the only two players at two-under.
Fine drive by Woods
Koepka's drive at the par-five finds sand left. Not sure it matters too much because this 600-yard five is out of range in two anyway, even for him.
Nice swing from Woods, as another driver finds the short stuff. The last two drives will be confidence builders. Apart from that air-mailed wedge at the 10th, Woods hasn't actually done much wrong so far no matter what his score suggests.
Two pars and a bogey for Woods
Beautiful lag putt by Woods...that part of his game looks sharp and he seems to have the pace of these greens down. That's back-to-back pars with a par five to come next.
Molinari can only two-putt and he drops to +2 alongside Woods after three holes. Two putts as well for Keopka who backs up his birdie at 10 with consecutive pars.
Woods settling down
Very solid shot from Woods, a raking long iron that finds the heart of the green. Odds-on a two putt par from there. Koepka had 191 yards in, and he also finds the green. You take four fours at this hole and run this week.
Molinari had to chop out, a familiar theme thus far, but his wedged third is still more than 30 feet away. That for an unlikely par.
The advantage of extra distance
Koepka cuts the corner with a smoking drive but Molinari takes a similarly aggressive line and does not have the distance to carry the dog-leg. Clears the bunker but settles down in the rough.
Conservative shot shape from Woods, assuming it was out of choice and not a mis-cue. Doesn't try and draw the ball with the shape of the hole - a high fade finds the fairway but it will be a long-ish iron in from there. Koepka might have a seven or eight iron in his hands.
Brutal do-leg left par four the 12th
The hole is 502 yards, and that bunker on the corner is 283 to carry. Koepka and Woods should be able to do it.
No change as we head to the 12th
Very good try from range by Tiger, as he scares the hole from 40 feet or so. The greens at Bethpage are very flat, so the mediocre putters out there can mount a challenge unlike, say, Augusta or Oakmont.
Surprise, surprise...Koepka pulls his birdie putt left so that's a chance gone. Still a very good start, mind. Par for Molinari and so too for Woods who need that to limit the damage.
Brooks looking imperious
Middle of the green from Woods at 11, neither disastrous nor great. Will have 35 to 40 feet for a birdie, or more likely two for a par.
Molinari in closer, around 12-15 feet for birdie, but what what an impressive start by Koepka who fires one in half as close again from 134 yards. A short putt coming up to go -2 thru two holes.
To the 11th
Another sensational drive down the 11th by Koepka, and Molinari follows him by finding the cut and prepared.
Interesting that Woods reaches straight for the three-wood, and that's a lovely shot. A tight draw that finds the fairway and gets him up and running. The 12th is a longer four though, so he will need to pull driver again soon.
Woods double-bogeys the 10th (his first)
While Molinari and Woods struggle, what a start for Koepka. Missed the green with his approach but holes a long-range putt from the fringe to birdie his first hole of the week. Formidable stuff.
Bogey five for Molinari. Woods chipped down to about five or six feet...and leaves the putt out to the right. That's a double-bogey six to start, and he needs a few pars to settle down.
Tricky start for Woods
This is a very rocky start for all concerned. This 10th green is one of many at Bethpage that is raised above the player with a bowl of thick rough in front - running the ball in is just not an option.
Woods tries to flight down his wedge but it flies too far. He now needs to get up and down to save bogey.
This rough look very penal
Molinari found his tee shot in the sand fortunately, but can only lay up into the fairway to leave a wedge in.
My word...if this is not a demonstration of the importance of finding the fairways. Woods was only three yards from the fairway and had 201 yards in, but he decided to just wedge down the fairway. Up and down for par from around 80 yards of so.
Woods off and running
Quite the wait on this 10th tee, but Koepka splits the fairway with a glorious drive. Very uncharacteristic start from Molinari, who perhaps digs deep for a little extra distance and hooks his drive into the junk left.
Woods up finally...a big high cut that starts down the left flank but may have just curved too much. Jumps into the first cut of rough, and much will depend on the lie. He didn't look too unhappy with it.
Molinari plays a provisional, and as is the way with provisionals it's dead straight.
WHY DIDN'T I DO THAT THE FIRST TIME?! Every golfer has said it.
Woods and Molinari meet again
An interesting sub-plot is Woods and Francesco Molinari are paired together again for the third major in a row. Molinari prevailed at the Open at Carnoustie, with Woods getting the better of him and the field at Augusta.
If Woods gets it going, it could be difficult to partner him due to the noise and movement of the crowd. Oh, and three-time major champion Brooks Koepka is also in the group.
Right, featured groups coverage is just beginning and Woods will be teeing off in less than 10 minutes time. Stay here to follow every shot of his USPGA Championship first round.
Jimmy Walker on the first escapes from the rough
You will be seeing plenty of this over the next four days: the world's best golfers struggling and scrambling.
Bogey for Tommy
Tommy Fleetwood has bogeyed the difficult 10th to start his week. There will be plenty of those between now and Sunday evening, the key to challenging will be keeping the real big numbers off your card.
Nice start from JJ Spaun (one hopes his nickname is Frog). He is two-under thru four and the tournament leader at this ridiculously early stage. It's a bit like looking at the Premier League table in August.
Can I start again please?
A disastrous beginning for Belgian Thomas Pieters with a triple-bogey seven at the 10th, his first, followed by a bogey at the 11th. That's four shots gone like confetti in the wind.
Pieters hits the ball a country mile and is well-fancied before many of these big events, but he has not got close to harnessing his talent yet. Not sure he has the full package between his ears, to be quite honest.
More shots of Tiger this morning
Just loosening up
You might be able to guess who is at the course...
Tiger is here, wearing a blue jumper on a cool morning in Long Island. I did see him hitting a few putts on the practice green a while ago, but I imagine he is now making his way to the driving range to warm up. Woods always finishes his warm up with the club he plans to use of the first tee, and looking at that 10th it will need to be driver.
After an extended break, the first round could prove the most difficult of the week for him, and he can be a jumpy starter at the best of times. Anything under-par today and Woods is in business, I reckon. He should get better as the week goes on.
The sun rises over this gorgeous AW Tillinghast design...
Why the two-tee start?
Starting off the first and the 10th can be a little confusing, but it's just for pace of play and to get everyone around before darkness falls. If you see a player with an asterisk next to their name, that means they are starting their round on the 10th.
At Bethpage, that is a far sterner starting a hole than the first. The 10th is a par-four that stretches out to just over 500 yards, so there's no easing into that round.
The best of the early tee times
Here are some of the groups we will be keeping an eye on this afternoon.
Off the 1st:
Off the 10th:
Stick marginal gains in your pipe and smoke it
John Daly favours Rothman's over resistance bands. Daly is using a buggy this week - or golf cart as they say in the States - because of osteoarthritis.
The Wild Thing's 1991 victory at Crooked Stick was arguably the best storyline in the tournament's history. Daly was a reserve and would not have played without a couple of withdrawals, and his bleach blonde hair and prodigious distance wowed fans.
A great talent, although sadly a wasted one. Divorce, alcoholism, obesity, gastric surgery, losing millions of dollars on Las Vegas slot machines...you name it, JD has been through it. And yes, Jack Daniel's was aptly his drink of choice.
Not for the faint hearted...
Here is the famous sign that greets players on the first tee at Bethpage Black. It's not uncommon for some of the tougher championship courses to impose a maximum handicap, even in the UK, but few have a 'hackers go home' notice board. At more than 7,400 yards off the back tees, you can see its purpose though.
Tiger Woods the pick of the early starters
We're in a New York state of mind for the next four days as the second major of the golf season - the USPGA Championship - tees off at Bethpage State Park, Long Island.
Scene of F. Scott Fitzgerald's classic novel The Great Gatsby, this affluent stretch of land to the east of Manhattan is also home to some of the most revered golf courses in north America, none finer than A.W Tillinghast's Black Course that hosts this week's championship.
A certain Tiger Woods has his yacht Privacy docked in the Hamptons, and resumed forward momentum in his lifelong quest to better Jack Nicklaus' record of 18 major championships with an unforgettable win at the Masters in April.
The boisterous New York crowds will whip themselves into a frenzy should Woods play his way into contention again, but he may have his work cut out. The great man has not played competitively since Augusta, and Bethpage Black will play a long slog with cool temperatures and fairways softened by rain. The US Open and Open Championships this summer look more presentable chances for Woods to add to his tally.
Dustin Johnson has just one major on his resume, which feels short change for such a preternaturally talented athlete. This stiff test of driving should be right up his alley, and Johnson is also prolific on the divisive Poa annua putting surfaces that are in play this week. Poa annua greens, which tend to get bumpy with lots of traffic on them, will also be a feature at the US Open at Pebble Beach where Johnson is a course specialist.
There is more of a hint of Congressional, where Rory McIlroy won his first major at the 2011 US Open, about Bethpage in these conditions. McIlroy should relish a soft course where he can throw his towering iron shots at the flags like darts. Consummate closer of majors Brooks Koepka also leads the betting and could well be the man to beat.
Jon Rahm, Rickie Fowler and Xander Schauffele have been knocking at the door of a first major championship, while Justin Rose and Tommy Fleetwood are back in form and leading the English challenge.
As Rich Beem, Shaun Micheel, Keegan Bradley and Y.E Yang will attest though, the PGA has a history of throwing up unlikely winners so we could well see an unfamiliar face lift the Wanamaker Trophy come Sunday.
Host of the 2002 and 2009 US Open, the real star this week should be the course. Bethpage Black is a handsome brute and feast for the eyes, demanding straight driving and immaculate distance control with the irons.
