Could this be a slightly underwhelming finish? Justin Rose comes in hot after cutting one out of the right rough, past a tree blocking his path to the green and skips through the dance floor and now Scottie Scheffler comes up short.

Matt Fitzpatrick is the odd one out and will have a birdie putt from just over 20 feet.

Tommy Fleetwood wraps up his round with a par as he shoots a two-over round of 72. Robert MacIntyre is into the clubhouse for an even round of 70.

Neither player particularly happy, neither player too disappointed.

Talk about a stroke of luck. Scottie Scheffler finds the gnarly stuff just off the 17th green from the tee but there are two sprinkler heads impeding his stance.

That allows him a free drop and he ends up being able to play from the right fringe instead.

The world number one rolls up to four feet and it looks like we could have a hat-trick of pars, with Justin Rose and Matt Fitzpatrick both on the dance floor in one and in close after their first putts.

Alex Smalley is still hanging around.

He may have dropped a shot at the 14th but he's seized that back two holes left thanks to a delicious wedge that left three and a half feet for birdie.

Back alongside the leading crew.

Shane Lowry speaking after his two-under 68 on day one at the US PGA Championship: "I think I just managed my way around the course. It got tricky. Everyone was kind of intrigued to see what the course was going to be like and what it was going to play like. As you see, it's playing quite difficult. And there are no low scores. Three under is the best score.

"When you get out of position, you need to try and get back in position, and you need to take your chances when you got them. I felt like I did a good job of that today.

"I was a little bit nervy at the start, to be honest. I struggled, I felt uncomfortable out there for a while. If anything, that kind of focuses me more - you're really just kind of focusing on the next shot at hand.

"I felt like I did a really good job of just staying patient, trying to make birdies when I hit good shots. If I hit bad shots, just not getting too flustered and just kind of managing my way around the course nicely."

Scottie Scheffler and Matt Fitzpatrick both get the reward of a birdie from wonderful iron play into the 16th.

Four-time major winner Scheffler plays a wede into four feet from 138 yards, while Fitzy's effort spins back but allows him to bury a putt for a timely four from 10 feet.

Rory McIlroy has spent playing of time on the range after a difficult end to his first round at the US PGA Championship.

The Masters champion finished with four straight bogeys and said afterwards the root of his problems was not finding the fairway.

No surprise to see him with his big clubs in hand on the practice ground.

A glorious approach from Shane Lowry sets up a birdie putt, which the Irishman drains from around 14 feet.

A great ending to his round but not Viktor Hovland's, who finds the left bunker and ends up carding his seventh bogey of the round.

Rounding up a couple of players we've not really mentioned but have impressed today - in the glut circling beneath the leaders.

Canada's Corey Conners - a ball-striker of some renown - and 2018 Masters champ Patrick Reed are both back in the clubhouse with tidy rounds of two under par safely tucked away.

Not a shabby place to be after this tough first day.

Spoke too soon about Robert MacIntyre, it seems.

He follows up a biridie at the 16th with a bogey at the 17th all because he overcooked his tee shot on the pare three.

Justin Thomas is deep into the bunker at the 16th.

He chips out of the sand but his ball skids beyond the hole which leaves him with a 20 footer for par but he is unable to pull it off.

Two bogeys inside three holes for JT.

Justin Rose is chuntering to himself as he leaves his first putt on the 15th miles short.

The Englishman is putting from 10 feet to save par and in it drops. It would have been so deflating had that one not found its target after his recovery over the past few holes.

Scottie Scheffler and Matt Fitzpatrick also take pars and on we go.

Norway's Viktor Hovland throws away the shot he's just worked so hard to get back.

His tee shot comes up way short on the par-three and when he races his chip - from the thicker stuff just off the edge of the green - way past the flag, he's in trouble.

Unlike Collin Morikawa, who plays into 10 feet and rolls in for birdie.

Robert MacIntyre is poised to finish well here.

The Scot picks up a valuable birdie with a putt from 12 feet on the par-five 15th.

Tommy Fleetwood comes up a few inches short with a birdie of his own.

The 2010 champion Martin Kaymer has been speaking to Sky Sports after his excellent round of 67: "The last few years, I haven't played well. I have had a lot of injuries but when I've been able to practise, I have felt I was trending in the right direction.

"I've enjoyed the test here- it's a really fair test. I stayed in it and it was a stress-free round. It was very enjoyable.

On his biggest motivations: "On Tuesday night, at the Champions Dinner, I got asked by one of the guys from the PGA of America if I still played. I'm playing this week! That really motivated me.

"I want to compete in all the tournaments I play in. I have put myself in a good position - there are three very difficult days ahead so I'll see where it goes.

Norway's Viktor Hovland picks up a stroke on the par-five 16th after clipping into two feet with his third.

It's only his third birdie of the day and adds a slightly nicer slant to a scorecard littered with bogeys.

Justin Thomas and Cameron Young both go agonisingly close to birdies.

Thomas rolls his putt just past the lip of the hole while Young skims one just past.

Both men have to settle for birdies.

Oh hello. There have only been a handful of birdies on the par-three 14th today, which is currently playing at 3.385.

The pin is in a horrible location but listen to the roar that greets one from Justin Rose.

The Englishman looked to be scrmabling for his par there after finding the left bunker but he chips out beautifully and points to the sky as he gets back to level par.

Meanwhile, Scottie Scheffler's momentum is checked as he wafts at a par putt from five feet and misses it high, while Matt Fitzpatrick's run of pars ends with a bogey four.

As Martin Kaymer joins the leaders, another interested party also moves to three under.

American Alex Smalley had a hot start of three birdies in his opening five holes before two bogeys around the turn knocked him back.

However, back-to-back birdies has reignited his challenge - and he's back with the leaders.

Martin Kaymer just comes up short for a dream finish but he'll absolutely pocket that tap-in birdie on his final hole.

He signs for a three-under 67 and that's a share of the lead.

Rolling back the years.
