Elaine Thompson-Herah is the best sprinter in women's history according to former 400m hurdles champion Edwin Moses.

The Jamaican sprinter became the first woman in history to complete the double-double by defending her Olympic 100 and 200 metre titles in Tokyo before adding her third gold of the Games in the women's 4x100m relay on Friday.

Thompson-Herah, 29, set a new national record with her earlier 200m success and recorded the second-fastest time in the history of the event.

Those achievements led Moses, a former American track star and two-time Olympic gold medallist, to the conclusion that Thompson-Herah is in a class of her own.

"She’s the best women's sprinter in history," Moses exclusively told Stats Perform. "She's proved that over and over.

"She came through at the right time, I think people were concerned about her and even when she ran against Dina Asher-Smith and didn't win, people were concerned but she was obviously in that final phase of training and she didn't want to show her cards. She did an outstanding job."

Thompson-Herah, fresh from her earlier 100m exploits, fell just 0.19 seconds short of Florence Griffith-Joyner's long-standing 200m world record that was set in 1988.

However, Moses explained there is a possibility that the five-time Olympic champion could complete the seemingly impossible and break Griffith-Joyner's records.

"It's possible. Obviously it's going to depend on the track," Moses continued. "If it's not the Tokyo track we don't know what she's capable of doing.

"She ran very, very fast there and those kinds of times are going to be much harder to run on normal tracks and aren't that Mondotrack that they had in Tokyo."

Jamaica completed a one-two-three clean sweep in the women's 100m sprint race in Tokyo, with gold medallist Elaine Thompson-Herah setting an Olympic record.

Thompson-Herah defended the title she won in Rio and became the second-fastest woman in history in the process, recording a time of 10.61 seconds.

Reigning world champion and compatriot Shelly-Ann Fraser-Pryce claimed silver, just .02 seconds ahead of Shericka Jackson as Jamaica completed a clean sweep which was celebrated on Twitter by Usain Bolt.

Legendary sprinter Bolt  – an eight-time gold medallist – retired in 2017, and the men's preliminary rounds struggled for big names in his absence.

Jamaica will have another chance of a medal in athletics, with 2019 world champion long jumper Tajay Gayle overcoming injury to make Monday's final with a leap of 8.14m.

Sweden sealed a one-two in the men's discus – Daniel Stahl taking gold and Simon Pettersson silver – while Poland won their second Olympic gold medal in a relay event in athletics, their mixed team succeeding in the same city in which their women had tasted victory in 1964.

NO LUCK FOR NOVAK

Djokovic's Golden Slam hopes were ended on Friday, and on Saturday, his medal hopes crumbled.

The world number one lost to Spain's Pablo Carreno Busta, who won 6-4 6-7 (6-8) 6-3 in the bronze medal match in the men's singles.

For Djokovic, it was a defeat which represented the end of his campaign.

He would have had another shot at bronze in the mixed doubles alongside Nina Stojanovic, but withdrew from that match, handing the medal to Ash Barty and John Peers of Australia in the process. 

"The exhaustion, both physical and mental, got to me and it's unfortunate that in the most important matches I just didn't deliver, but I gave it all," said Djokovic, whose attention will now turn to winning the US Open to complete a calendar Grand Slam.

BLACK FERNS RIGHT RIO WRONGS

New Zealand's women clinched gold in the rugby sevens on Saturday, overcoming France 26-12.

The Black Ferns cruised to the final in 2016, but slumped to a defeat to rivals Australia. Co-captain Portia Woodman was pictured in tears on the field in Brazil, yet her team made no such mistake this time around.

"Crying underneath the posts was one that I looked back on, but now it's gone," Woodman said. "Not when I look at this," she added, gesturing to the gold medal around her neck.

"Yeah, we've got titles and we've won things, but I want our group to be good people and show the world that you can be a good, genuine person and still have success," Woodman's fellow co-captain Sarah Hirini said. 

"Our programme allowed that. Things like this happen because you're able to be who you are."

In the bronze medal match, Fiji defeated Great Britain 21-12.

"We are totally gutted. We really thought we could come here and get a medal, but we just weren't good enough," conceded Team GB's Hannah Smith. "Fiji really brought it to us today, so fair play to them."

DEBUT BRONZE FOR WILSON, CHINA TAKE WINDSURFING GOLD

There was joy for Britain out on the water, however, as Emma Wilson – an Olympic debutant – won bronze in the women's windsurfing.

Wilson was already guaranteed a medal due to winning four races in the lead up to the final. The 22-year-old missed out on silver as Lu Yunxiu of China kept within a boat's length to claim the gold.

Charline Picon took silver to follow up her win in Rio five years ago.

"It's amazing. I tried so hard in that race - I just kept going and going," said Wilson. "I just want to win, but any medal is amazing. I'm super happy and I just gave it everything I had."

CHINESE TAIPEI WIN MAIDEN BADMINTON GOLD

Lee Yang and Wang Chi-Lin took home Chinese Taipei's first badminton gold on Saturday with a victory over Liu Yu Chen and Li Jun Hui of two-time reigning champions China in the men's doubles final.

Their victory brought up the seventh Olympic gold for Chinese Taipei – the previous six having been split across weightlifting (four) and taekwondo (two).

Malaysia claimed their first medal in Tokyo thanks to Wooi Yik Soh and Aaron Chia triumphing in the bronze medal match.

In total, Malaysia have claimed 12 medals in their Olympic history, but are yet to clinch gold in any event.

Elaine Thompson-Herah insists she did not have any record in mind after her stunning victory in the women's 100 metres final at Tokyo 2020.

The Jamaican defended the title she won at Rio 2016 in sensational fashion, sprinting home in an Olympic-record time of 10.61 seconds to deny Shelly-Ann Fraser-Pryce becoming the first woman to win the same athletics event at three different Games.

It was the first time Thompson-Herah, who has endured a frustrating time with Achilles injuries since her crowning moment in Rio five years ago, had run below 10.7s.

But the 29-year-old was focused only on winning and believes her benchmark will too eventually be broken.

"Going into the final I didn't have a time in my head, I was just trying to execute the best race and I had the best race tonight because I got the PB," she told a post-race news conference.

"I wasn't looking at any record or any time as I said. But eventually those times will erase, even if it takes four or five years they will [be] erased [by] somebody. 

"Other women are coming up, rising, so to run this Olympic record tonight sends out a message anything is possible."

Fraser-Pryce had been the favourite to win the 100m for a third time in her decorated career but had to settle for silver, while Shericka Jackson completed a Jamaica one, two, three.

Thompson-Herah hailed Fraser-Pryce, who said this will be her final Olympics, as a benchmark in the sport.

"I wasn't checking the stats [of my races against Fraser-Pryce] I wasn't even counting," she added.

"She's a talented and a great athlete of course. She set the barrier for us younger generation coming through. As for a mum, she's soon to walk away from the sport, she's left her mark."

On the race itself, which saw Fraser-Pryce tense up over the last 30m with her rival right on her shoulder, Thompson-Herah confessed she had some nerves at the starting block.

"I've not seen the race as yet, I was super nervous but I had to control it. I knew all eight ladies were nervous," she said.

"We had done everything we could have done there is nothing else I could change. I think I had the best race tonight, I don't know if there is more to come but [I have] a PB and Olympic record so therefore tonight is the best race."

Usain Bolt's one-time great rival Yohan Blake has declared he will refuse all COVID-19 vaccines, and would rather miss the Tokyo 2020 Olympics than be immunised.

The Jamaican sprinter won silver in the 100 metres and 200m at London 2012, as Bolt landed gold in both races. Only Bolt has ever run faster than Blake over those distances.

Speaking on Saturday, Blake expressed his opposition to being given a vaccine.

The International Olympic Committee has indicated athletes will not need to be vaccinated before taking part in the Tokyo Games, but vice-president John Coates recently said it was "certainly being encouraged".

The Olympics, postponed from last year due to the coronavirus crisis, is due to run from July 23 to August 8.

Quoted by the Jamaica Gleaner newspaper, Blake said: "My mind still stays strong, I don't want any vaccine, I'd rather miss the Olympics than take the vaccine, I am not taking it.

"I don't really want to get into it now, but I have my reasons."

Blake, who won 100m gold at the 2011 World Championships, is now 31 and Tokyo may be his last chance to shine on the Olympic stage.

He said in a video posted late on Saturday night: "Love me or dislike me, but I am here for a reason, to serve God, and at the same time be a servant for God to help each and every one.

"I am a righteous man, I am a man of God, and I believe that everybody do have a choice in life, no matter what. And I want to tell someone, don't let anyone take away that choice from you.

"At the end of the day if anything should happen, nobody's going to be by your side apart from God. No one is going to be there to hold your hand, it's going to be you.

"Follow your mind, don't follow the crowd. At the same time, be respectful to each and every one. Don't let no one take away your choice."

Jamaica has had 422 confirmed deaths from COVID-19, and 23,263 cases, the country's government announced on Saturday.

The country has yet to receive first shipments of a vaccine, but health minister Dr Christopher Tufton said on Friday they would "soon" arrive.
