Ludvig Aberg has such a classy, silky smooth swing.

And in fairness there's a real retro look to his green trousers and white polo shirt.

But he finds the front bunker on the fourth and his promising start is halted with a bogey, when he clips five feet past and can't sink the return putt.

Rory McIlroy and Akshay Bhatia both save their pars. The Northern Irishman was downtown there and rolled his first putt about four feet past.

So I'm trying to figure out what's happened with Jordan Spieth's third shot at the 13th.

According to the Masters website shot tracker, he's gone slightly awry - to the tune of four entire holes.

I've not totally written it off as a technology error.

After all, Spieth's ball is probably the most well travelled in golf...

In seemingly every major, we have a moment when Corey Conners of Canada sneaks up the leaderboard and it's happened on Thursday this time.

Birdies at 15 and 17 see him strolling down the 18th at three under par, one shot back from Tyrrell Hatton.

This group have been scrapping their way down the second hole - and Jon Rahm is punished with an avoidable bogey.

Tommy Fleetwood and Wyndham Clark card pars, but this has been the easiest hole on the course today. None of the marquee trio have cashed in.

Collin Morikawa air mails his second shot on 15 as he goes for the green in two, and it lands miles over the green and bounds down towards the water on the 16th hole.

Joaquin Niemann plays a similar shot and those two will face horrifying chips back onto the putting surface.

Scottie Scheffler will be fuming at that as he's started with an eagle chance on the 13th green but ended up with a three-putt for par after missing a six footer.

OK, so it's he's not dropped a shot officiallly, but that will feel like one he's left out there by the end of the day.

Bryson DeChambeau gets off the mark with a birdie at the par-five second.

Always helpful when you can nail your drive over 360 yards.

Wow. Ludvig Aberg is right and short of the third green and zips right through it with a little chip that trundles on and on.

There's a huge roar as Rory McIlroy chips close with his second and an even louder one as Aberg, playing in only his second Masters, chips in for birdie.

That is brilliant from the Swede. In fact it's going to be birdies all around with McIlroy tapping in and Akshay Bhatia continuing his strong start.

The way Scottie Scheffler moves his dancing feet during his swing you wonder how he can do so well at Augusta considering almost every shot is on a slope, but he does it again as he smacks his approach from 205 yards to find the 13th green in two.

Outside chance for an eagle coming up.

Justin Thomas, meanwhile, also goes for the green but he's hammered his shot into the azaleas and we're not sure if he can find this one...

Australia's Jason Day, who has a runners-up finish here from 2011, is quietly making a move up the leaderboard.

He's gone back to back at 12 and 13 - and is two shots off the lead.

And of course he's got one of his typically statement shirts on too.

Well undercooked from Rory McIlroy, who putts from just off the green at the second and leaves himself a tricky little putt for par, which he sinks.

Meanwhile, Ludvig Aberg has a look at a birdie...that's also slightly short of gas but he tidies up from gimme range.

Akshay Bhatia does knock in his birdie putt from around six feet.

Joaquin Niemann missed his par putt on the 13th, but he's responded by drilling his tee shot 326 yards off the 14th tee and nailing an iron onto the green 20 feet from the flag.

Sunk. Tyrrell Hatton gives his tee shot what it deserves and buries his birdie putt at the 12th.

Outright leader.

He then watches on as Jordan Spieth immediately hands back the shot he had won at the previous hole and drops to level par.

Aaron Rai is battling hard to make sure he finishes this debut round in good shape, and this chip-in from just off the 17th really helps with that.

He'd just bogeyed the 16th after finding the bunker off the tee so that's another good response. One to go.

Well played Jon Rahm, nudging in for a par save after finding the sand and missing the green at the first.

No such luck for Tommy Fleetwood though who starts his challenge with a frustrating bogey.

You never lose it!

Fred Couples proves that with a magical moment on the 14th... he's just holed out from 191 yards for an eagle. Boom boom.

The 65-year-old American, playing courtesy of a lifetime exemption in honour of his 1992 victory, is up to tied seventh on the leaderboard.

While we focused on Joaquin Niemann messing about in the creek, Collin Morikawa had cracked one 207 yards onto the green in two, and then casually rolled in his put from 35 feet away for eagle!

Out of nowhere Morikawa suddenly now has a share of the Masters lead.

Rory McIlroy does not like that all judging by his groan on the second tee.

His ball is heading off to the right and finds the fairway bunker. He should still be able to get somewhere close to the green on this 585-yard par five mind.

He lays up to the middle of the fairway and then skips through the green with his third. Work to do for the four-time major winner, who is chasing a career Grand Slam (again) at the Augusta National.

Magnificent from Tyrrell Hatton at the 12th.

Totally unflappable in the notorious winds that flank this sneaky par three, he flights his tee shot to within six feet.

Birdie chance to take the outright lead.

Oh dear, Joaquin Niemann gets a lucky break on 13 when he finds the creek with his second shot but there's not a lot of water in it and he's able to take a swipe at his ball from the sand.

However, he doesn't give it enough beans and the ball stops at the top of the hill and rolls back further into the creek and gets wet.

He can still get a club on it though and manages to escape up onto the green a leave a par putt.
