August 1 Tokyo 2020 Olympics news and results

He's come close to grand slam victories before, and now, 24-year-old Alexander Zverev has a standout victory to his name.

The German comfortably defeated the Russian Olympic Committee's Karen Khachanov 6-3 6-1 to take home the gold medal in the men's singles tennis on Sunday.

The 79-minute victory at the Summer Games, coming after his battling victory over world No. 1 Novak Djokovic in the semifinals, means that he is now an Olympic champion -- a feeling Zverev says he can't "compare."

"This is so much bigger than anything else in sports, especially in tennis. This is an incredible feeling me for me right now," he told the media afterwards.

"There is nothing better than this. You are not only playing for yourself, you are playing for your country. The Olympics are the biggest sporting event in the world.

"The feeling I have now, and will have -- nothing will be better."

Nina Derwael of Belgium won gold in the uneven bars as the artistic gymnastics wrapped up for Sunday.

The 21-year-old produced an excellent display to earn herself a score of 15.200, ahead of Anastasiia Iliankova of the Russian Olympic Committee in second.

Derwael is a two-time world champion and a two-time European champion on the uneven bars. She competed at the 2016 Games, finishing 19th in the all-around final.

Team USA's Sunisa Lee -- who won the all-around gymnastics gold earlier this week after her teammate Simone Biles pulled out -- won the bronze medal.

The 18-year-old American picked up her third medal of the Olympics after the US won the silver in the team event.

The Summer 2020 Olympic Games are well underway in Tokyo. If you're watching in the US, here's a look at some of the key events to check out today. Remember: Tokyo is 13 hours ahead of US Eastern Time, but many of the events are replayed in US primetime hours.

Here’s your full guide on how to watch the Olympics and the entire schedule. In between watching events, check out our gallery of the most memorable photos of the Games so far.

After Jamaica completed a clean sweep in the women’s 100m final on Saturday, it’s now time for the men’s edition. If it can deliver even half the drama that the women’s race did -- when Elaine Thompson-Herah clocked a new Olympic record of 10.61 seconds -- then we’re in for a treat.

With less than two-tenths of a second separating all of the qualifying times from the men’s semifinals, this one is too close to call. China’s Su Bingtian was the fastest in 9.83 -- a new Asian record -- but only 0.01 seconds separated him and USA’s Ronnie Baker and Italy’s Lamont Marcell Jacobs.

Bingtian became the first Chinese man to reach the men’s 100m final. 

Trayvon Bromell, who won the US Olympic Trials in June, failed to qualify.

This will be the starting line-up at 8:50am ET:

Su Bingtian (China)

Ronnie Baker (USA)

Lamont Marcell Jacobs (Italy)

Akani Simbine (South Africa)

Fred Kerley (USA)

Zharnel Hughes (Great Britain)

Andre De Grasse (Canada)

Enoch Adegoke (Nigeria)

Usain Bolt has loomed large over this event for the past three Games. Who will be the next Olympic champion now that the Jamaican has hung up his spikes?

Team GB's Max Whitlock successfully defended his Olympic gold medal in the pommel horse discipline on Sunday.

Going first in the final, the 28-year-old produced a magnificent display to earn a score of 15.583, ahead of Chinese Taipei's Lee Chih-kai in second.

Japan's Kazuma Kaya took the bronze medal.

It is Whitlock's third Olympic gold medal. He won gold in the pommel horse at the 2016 Rio Games, as well as gold in the floor exercise.

He is the first man to successfully defend the pommel horse title since 1980.

At the Rio Games, Whitlock made history when he won Great Britain's first medal in the all-around event for 108 years.

Upon becoming a double Olympic champion in the pommel horse, Whitlock called the feeling "surreal."

"I can't quite comprehend what just happened. It's been a whirlwind journey, and I am massively grateful," he told the media. 

"I was on first, so it was the first time I have been able to watch a whole pommel horse final; it's just surreal. 

"I never expect medals. I like to go in with the potential to get a title if I go clean and the potential is there. And the build-up, the routine, I couldn't do anything more. 

"I am over the moon to come away with gold. 

"I try not to let my this third Olympics feel different to the others. I try to go into any Olympic Games with the same drive and hunger, but this morning I really felt the nerves. It was the most nervous I have ever felt in a competition, so it's even more remarkable that I managed to perform under this pressure."

At least 30 people have suffered heat related illness at the Olympic Games, Tokyo 2020 spokesman Masa Takaya told a press briefing on Sunday.

Toshiro Muto, Director General of Tokyo 2020, said most of those affected were contractors, volunteers and staff members, adding that organizers have taken countermeasures to minimize its impact on the Games. Muto did not say if any athletes were taken ill in the high temperatures.

The patients only developed mild symptoms and all of them have recovered after taking some rest, added Takaya.

This comes as a trackside thermometer at an athletics stadium in Tokyo showed temperatures reached 40 degrees Celsius -- or 104 degrees Fahrenheit -- on Sunday, according to the Reuters news agency and sports journalists at the Games who posted photos showing the high reading.

Locals seem to be warming to the Tokyo Olympics.

Prior to the beginning of the globe's biggest sporting event, protests in opposition to the hosting of the Games took place across the country due to the rising number of Covid-19 cases in Japan.

Tokyo reported 3,058 new Covid-19 cases Sunday, according to Tokyo Metropolitan Government data. 

The number of new cases last Sunday was just 1,763, and Tokyo has experienced consecutive days of record-breaking infection numbers since Tuesday. 

On Friday, Prime Minister Yoshihide Suga announced the extension of Japan’s Covid-19 state of emergency to the end of August, while expanding the restrictions to cover four new prefectures -- three of which surround Tokyo.

However, with the Games in full flow and the best athletes strutting their stuff, locals seem to be coming round to the idea of the sporting spectacle.

Even though they can't get inside venues to watch the action in person, they still want their Tokyo 2020 souvenirs. 

At the Aqua City shopping mall in Odaiba on Sunday, there was an hour-long line to enter the Olympic store pop-up shop.

Germany's Alexander Zverev comfortably defeated the Russian Olympic Committee's Karen Khachanov 6-3 6-1 to take home the gold medal in the men's singles tennis.

Zverev beat world No. 1 Novak Djokovic -- who was aiming for a historic 'Golden slam' -- in the semifinals.

And he continued his excellent form into the final -- his big serving proving vital in the straight sets victory which took just an hour and 19 minutes.

Zverev, who was the No. 4 seed entering the Summer Games, already has an extensive résumé despite being just 24 years old.

He was the 2020 US Open finalist and has reached the semifinals in two other grand slams. He won the 2018 ATP Tour finals.

The world No. 5 showed his class from the first point, with Khachanov struggling to gain a foothold against his big-hitting opponent.

Rebeca Andrade won the gold medal in the vault competition on Sunday.

The Brazilian gymnast finished with a score of 15.083 average doing a Cheng and an Amanar, ahead of Team USA's MyKayla Skinner who had a score of 14.916.

The gold medal is Andrade's second medal of the Summer Games, after finishing just behind the US' Sunisa Lee in the individual all-around final to claim silver.

Andrade's gold is Brazil's first ever gold in women's gymnastics.

Skinner was Team USA's replacement for Simone Biles after she withdrew citing her focus on her mental health.

South Korea’s Yeo Seo-jeong won the bronze medal, the country’s first Olympic medal in women’s gymnastics. Her dad had won a silver in men’s vault in 1996.
