The Open Championship First Round: LIVE leaderboard and updates from Royal Troon

S. Lowry -5 (66)

A lovely birdie on the 18th gives Lowry the solo lead at five under, and the crowd goes wild.

He's been sublime today. The Irishman was faultless with not a single blemish on the scorecard.

Could he double his major tally this week? We wouldn't be betting against him based on today's evidence. 

T. Woods +8 (79)

Woods was far from his best today, and he looks like he's struggling with a lack of tournament sharpness. 

While he still has one round to go, it looks like he will need to pull a rabbit out of a hat if he wants to see the weekend.

J. Spieth -1(16)

Jordan Spieth makes an incredible eagle on the 16th hole to get back into the red. 

He couldn't have played the par five much better, with his approach shot being one of the best we've seen today. 

The American has had to work hard to stay at level par for the last few holes, but he's shown flashes of the player we fell in love with almost a decade ago. 

D. Brown -4 (11)

What a day Dan Brown is having. 

This is his first major appearance, but you would never have guessed it by looking at his scorecard. 

He must have had roughly 40 feet for birdie on the 11th, and he dropped it right in the front door to join Lowry at the top of the leaderboard. 

P. Mickelson +2 (73)

Mickelson nearly holed his second shot on the 18th hole but will undoubtedly be happy with the tap-in birdie to finish. 

The 2013 Open champion is in a solid position heading into Friday and will still fancy his chances of adding to his major tally at a venue where he once came so close. 

D. Brown -3 (10)

Daniel Brown has made an excellent start to his Open Championship with a bogey-free first ten holes. 

The Englishman has also made three birdies and now sits just one shot back from Lowry. 

J. Spieth E (13)

Spieth has had to battle today, and a well-earned birdie on the 13th hole moves him back to level par. 

He's shown some excellent touch with a wedge in hand through round one, and his putter has joined in on the fun now. 

Another birdie through the final stretch will leave him in an excellent position heading into Friday. 

B. Koepka -1 (15)

Koepka's scorecard is covered in colour, and he adds another drop of ink with a bogey on the 14th hole. 

Having missed the fairway right, he always had his work cut out, and unfortunately for the LIV Golf star, he couldn't convert a mid-range par putt to stay in a tie for third place. 

X. Schauffele -2 (15)

A wayward second shot left Schauffele with a tough up and down to save par on the 14th hole. His chip was excellent from the thick rough, but unfortunately, there was a bit too much speed on the putt, and it lipped out, leaving a tap-in bogey for the US PGA champion.  

S. Lowry -4 (12)

Lowry's putter comes to the rescue again, maintaining his one-shot lead at the top. 

The Irishman has eight pars and four birdies today. Justin Rose is the only player to have gone bogey-free on day one so far, but his Ryder Cup teammate might soon join him. 

X. Schauffele -3 (11)

An excellent 45-foot putt finds the bottom of the cup on the tough 11th hole to see Schauffele grab a share of the lead. 

With the weather improving, the American could certainly stretch his legs at the top if he keeps up his current form. 

Lowry -3 (10)

Lowry was destined to drop a shot on the 10th hole following a pretty sloppy chip shot. However, his putter rose to the occasion once more, and the Irishman retained his position at the top of the leaderboard with an excellent par save from distance. 

T. Woods +4 (10)

Woods looks to have knocked his tee shot out of bounds right on the tough par four 11th. 

He's teed up a second ball and piped it straight down the middle. We will have to see whether the first is dead, but whatever happens, he's in a spot of bother. 

S. Lowry -3 (9)

Lowry makes the turn with a share for the lead at three under. 

The Irishman had a tester for par on the 9th, but his putter has been red hot today, and it came to the rescue once again from about eight feet. 

With wet and windy conditions predicted for the remainder of the week, Lowry will fancy his chances of getting his hands on the Claret Jug for a second time. 

C. Morikawa +3 (8)

The Postage Stamp damages Morikawa's scorecard as he walks off with a disappointing double bogey following some sloppy short-game work. 

The shortest par-3 on the Open rota only requires a flick with a wedge from the tee box, but it's already inflicted its fair share of pain today. 

P. Cantlay E (8)

When Cantlay's tee shot sailed into the bunker right of the 8th green, he would have been thinking bogey wouldn't be a bad score. 

However, a stunning shot from the sand sees him walking off with a birdie. 

The Postage Stamp has taken some prisoners today, but Cantlay is certainly not one of them. 

T. Woods +3 (7)

Woods' tough start continues as he three putts the 7th hole to move to plus-three for the round. 

There was a time when Woods never missed the tricky short ones, but unfortunately, that now seems like a long time ago. 

B. Koepka -2 (7)

Brooksy is on a roll, and he's now made four birdies in a row to move into a tie for second place. 

J. Montojo -2 (1)

It's a start to remember for the Spanish amateur Montojo as he holes out on the 1st hole for an incredible eagle. 

B. Koepka -1 (6)

The big-hitting American has made three birdies on the bounce, and following an excellent approach on the 7th, he looks poised to make it four.

M. Jordan -1 (7)

Birdies on the 6th and 7th holes move Jordan into the red for the first time today.

He's now fully repaired the damage done on the 2nd, where he made a double bogey.
