Xander Schauffele takes a dropped ball, his backswing clips a few branches and the ball squirts across the fairway.

How much will this hole cost the current leader?

While Xander Schauffele works out how to play this, the recent Open winner Collin Morikawa sinks a putt on the 18th to finish on 15 under. That puts the American in a tie for fourth.

Did I say the rough? Xander Schauffele's managed to locate his ball and it's beyond the rough, beneath a bush.

So Rory Sabbatini is the clubhouse leader. How will Xander Schauffele react?

Well, he's just sent his tee shot off to the right and into the rough on the 14th, that's how!

An official is still trying to locate it.

No worries for playing partners Paul Casey and Hideki Matsuyama.

Couple of markers there for Paul Casey to aim at. The Briton has just dropped a shot on the 13th though and slips to 13 under.

Rory Sabbatini's playing partner CT Pan finishes on 15 under after an eight-under 63.

That would have been the Olympic record had the man from Chinese Taipei putted before the Slovakian.

Oh hello, Rory Sabbatini has just sunk a cracking birdie putt on the 18th to move clear in second on 17 under, just one off the lead.

The Slovakian was celebrating before it was even near the cup. And no wonder, he's finished with a 10-under 61 for the day - that's an Olympic record.

And it sets a challenging clubhouse lead for the others to try and beat.

Paul Casey remains at 14 under, it is just getting to the point now where unless he makes a charge, it is just not going to happen for him.

Abigail Irozuru was not selected for London 2012 and missed the 2016 Games in Rio due to a ruptured Achilles.

She then retired but is now well and truly on the comeback track and making the most of her chance on the big stage after reaching the final in Tokyo.

"It is extra special to be here at this very weird Olympic Games," she said.

"This has literally been the highlight of my whole Olympic experience so far so I'm loving it.

"It was a nice confidence boost to get a season's best, to finally jump over 6.70 this season, and to hit the automatic qualifying because that's what I came here to do.

"There is more to come, there's things that I've been working on and I'm starting to execute as I'm building through the rounds, so hopefully with six rounds in the final it will come."

Abigail Irozuru and Jazmin Sawyers reached the women's long jump final in Tokyo.

Irozuru produced a season's best of 6.75m to achieve the automatic qualifying distance at the Olympic Stadium on Sunday morning.

Sawyers also progressed after finishing in the top 12 with a distance of 6.62m but Lorraine Ugen could only managed 6.05m and missed out.

Frazer Clarke talks to Nick Hope after he progresses through and is guaranteed a medal courtesy of Mourad Aliev's disqualification: "I'm an Olympic medallist. That's not the way I wanted it to go. To be fair that's the fifth time I've fought him and those cuts are not from punches.

"Our coaches are a massive credit. Having no crowds have been a blessing in disguise - I can hear instruction and I can go and carry it out. It's going to take more than a cut to stop me.

"I'm going to go back, rest up and we go again."

Clarke has two gashes, both would rule him out of any professional fight, no matter where you are. They have got to do some serious work behind the scenes.

Look at Frazer Clarke doing his bit, he is going over, he is consoling him [Mourad Aliev]. Saying 'it is sport, we will fight again' he is the diplomat, that is why he is the captain.
